Laser technology is used in almost every scope of life, from the
miniscule lasers in CD players to the lasers used to scan
groceries in the checkout line to the massive lasers in
aeronautics design. The discovery of laser technology and the
subsequent building of ever-improving lasers have benefited the
human race tremendously, particularly through medical advances.
Medical lasers cause medical procedures to be quicker, better,
and easier than their traditional counterparts. The only
drawback is increased cost.

In 1917, Albert Einstein was the first person to suggest the
basics of what would become lasers, by discussing the theory of
Stimulated Emission, which is a type of electron transition in
which a photon is emitted from an atom causing a chain reaction
with other atoms to repeat the action. In fact, the word laser
is an acronym for Light Amplification by the Stimulation
Emission of Radiation. Charles Townes, an American physicist,
further developed the idea with microwave (invisible) light in
the mid- to late-50’s and Theodore Maiman built the first
working optical (visible) light laser in 1960. Improvements and
variations on hundreds of kinds of lasers continue to be made
since the 1960s. Those involved in quantum mechanics have been
studying some form of lasers, either in theory or in reality,
since the 1920s. Uses for laser technology are widespread and
are included in such important fields as medical/surgery,
communications, design, manufacturing/industry, and research.

Medical/Surgery

The advancement of medical lasers has vastly improved the ease
and success of surgery. The cost, however, is greater than that
of other treatments, though scarring is much less with lasers
and lasers work much more quickly than older surgical options.
Incisions are more precise and easier to control. Some medical
areas in which lasers have deeply refined treatment options are
in laser eye surgery, oncology, neurosurgery, cardiology,
dermatology, veterinary surgery, and dental surgery.

Communications Televisions, telephones/ cellular phones, and
computer systems all benefit from the use of lasers. Lasers are
able to carry the huge amounts of channels and frequencies
required by these high-tech devices. Lasers have proven the best
communication device to have in the space age.

Design

Lasers have transformed the world of design by making it
possible for designers to perform with precision that was
previously unavailable. Lasers are used to design digital and
three-dimensional objects with much more ease and accuracy
through scanning, cutting, copying, and digital archiving. From
designing a building to designing landscape, lasers prove to be
the best option for fast and easy design.

Manufacturing/Industry

Lasers have improved the manufacturer’s ability to produce
tenfold. For example, with a laser cutter, a clothing
manufacturer can have fabric patterns cut much more quickly and
more accurately in no time. A jeweler has much more precision on
his side when employing lasers to work on fine gems. Airplane
designers can construct an aircraft much more efficiently and
with greater results using laser technology.

Research

The use of lasers in research enables scientists to uncover much
more detail and detect very slight movement when studying
matter. The lasers can be tailored to only respond to certain
colors or movements and, in that way, they provide much more
specialized work in research environments.

The world of laser technology is always expanding by producing
new applications and ways to benefit people. The dependence that
the modern culture has on lasers is amazing considering that it
was not prevalent until the past forty years.

Everyone seems to have gotten busier and everyone also seems to
have learned to multitask better. If you do one thing at a time
these days there’s something drastically wrong with you.
Everyone drives and talks on the phone. People at work talk on
the phone and walk around their office. Everyone has to be doing
something and something else at the same time. Thank God for the
invention of the headset.

Computer headsets are great for not having everyone around you
hear everything that is going on. Through our computers we can
listen to music, talk on the phone and videoconference. Using a
headset while on the computer allows you to work and not disturb
the people around you and keep your information private so it is
not blaring over the speakers.

Telephone headsets have become more popular since the cellular
phone was invented. Certain states have laws that you cannot
talk on the phone while driving. Headsets attached to phones
allow the busy individual who must talk on the phone while
driving, to continue to do so and not endanger the people around
them. The headset for the phone also allows individuals to
travel while talking. No longer are we restricted by how far the
phone cord will reach or how loud we can yell to be heard over
speakerphone from another room in the house. Have headset – will
travel… MP3 headsets or musical headsets are designed for the
avid music listener or the hardcore athlete. Headsets for the
music listening crowd have gotten smaller and smaller as the
devices to play the music has gotten smaller and smaller too.
There are the headsets that go over the head like a hair band,
ones that go behind the head and still sit over the ears, and
ones that sit right inside the ear. Depending on your activity
level depends on the appropriate headset for you. As mentioned
there are various styles of headsets. Cordless headsets do exist
but they cannot all be used with a cordless phone. Purchasing a
headset is a very personal decision and if you can, see if you
can try them on before actually purchasing it.

The ear on a human being is a unique design to everyone. An
earpiece that just sits in the ear, will not sit the same in
yours, as it will your friends or spouses ear. If you wear
glasses, you’ll need to get a very thin earpiece and headset.
You can even get one that clips onto the frame of your glasses
and then sits comfortably inside the ear. There are headsets
that have just earpieces that sit in the ear, but they also have
a sort of clip that sits around the ear for added stability. And
then there is the classic style that sits over the head and has
a padded earpiece attached to either side and rests over each
ear.

Whenever wearing a headset it is important to remember that you
should keep the volume at a comfortable level. When listening to
music it is not necessary to listen to it full blast over your
ears – this could impair your hearing after prolonged use at a
higher volume level.

When you think of video conferencing you probably picture a
webcam perched on a computer or monitor recording your image and
sending it out to the world. While webcams are most frequently
used by online conference participants, it is also possible to
get the work done with a digital video camera. Which webcam or
digital video camera you opt for depends on your needs. Here are
some points to consider when making your selection.

Webcams

Nowadays, web cams can be found for under $20 and go all the way
up to $150. The difference between the high end cameras and the
starter web cams are usually due to the quality of image that is
put out.

First, take a look at the resolution of the camera. Ideally you
should get a webcam that can produce at least a 640×480
resolution.

Then check how many frames per second the camera can handle. For
video conferencing the ideal level is 30 frames per second (fps).

Finally, find out what kind of sensor the camera uses. The
better web cams use CCD technology instead of CMOS. Also,
remember that most webcams connect to computers with a USB cable.

Digital Video Cameras

For an even better result (sharper and faster images), you can
use digital video cameras. These are the same devices that are
used to record home movies, etc. Digital video cameras start as
low as $250 and go up to thousands of dollars. In order to use a
digital video camera, you need to make sure that the device
supports a USB or a Firewire output and that it can be used as a
webcam and connect you with online applications.

Whether you use a webcam or a digital video camera depends on
the type of conferencing that you will be doing.

If you’re meeting in a manner in which the quality of the video
is not too important, then a lower end webcam will probably
suffice. However, if you need quality video, then a higher end
webcam, or even a digital video camera will be required.

If you’ll be in a conference room setting, in which you need to
get more than one person on camera, a digital video camera with
tilt/pan/zoom capabilities will work best.

Firewire digital video cameras provide images that are so nice
that you can see the second hand of a watch sweep by. You can
also see details of products and items that normal webcams
simply cannot provide. This is because firewire handles the
processing of video much better than USB does, allowing for
smoother images and better quality.

When you are out shopping for webcams, take a look at Logitech
products. They are one of the leaders in this field and have a
wide variety of models. They offer great products at reasonable
prices. For digital video cameras, Canon offers a good selection
and devices of excellent quality.

So, consider your needs and your budget and then find a webcam
or a digital video camera that is best for you.
