Laser Essay Examples
Optical Fibre is used to transmit light between 2 ends of the fibre, a ‘waveguide’ or ‘light pipe’. It is very thin, around the thickness of a human hair, and made of transparent fibre made of glass or plastic. Optical fibre is sometimes known as Fibre Optics when used in science and engineering. Instead of…
Laser hair removal was performed experimentally for about 20 years before it became commercially available in the mid-1990s.One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998. The efficacy of laser hair removal is now generally accepted in the dermatology community,[citation needed] and laser…
Laser communication, often referred to as free-space optics (FSO) or free-space laser (FSL) communication, is similar to fiber optic cable in terms of carrier wavelength and bandwidth capability, but data are transmitted directly through the atmosphere via laser beams over paths from a few meters to 4 km or longer. FSL uses lasers in the…
Modern optical metrology uses precise lines and planes in space from which measurements are made. Because this method creates these features using light it has become known as optical tooling. The 35 year old historical development and current technology of laser instrumentation as used in optical tooling is discussed in detail. This includes the how…
