An optical computer‚ besides being much faster than an electronic one‚ might also be smaller. Bright flashes of laser light can be sent hundreds of miles along fine strands of specially made glass or plastic called OPTICAL FIBERS. Instead of transistors‚ such a computer will have TRANSPHASORS And unlike transistors can be built to handle several incoming signals at once. Beams of light can crisscross and overlap without becoming mixed up‚ whereas crossed electric currents would get hopelessly

multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel. Regardless of the method‚ information is stored in binary code‚ strings of ones and zeroes. Optimally‚ the channel capacity for a signal A is x bits/s where x does not account for signal deterioration (Figure 1). Figure : Data Transmission of a Signal‚ A.

later set out in search of tattoo removal techniques. But thanks to the new laser technology that makes tattoo removal much safer and easier than the traditional salabrasion or excision procedures. Before opting to remove the ink using laser treatments‚ here are the important things you must know. Laser tattoo removal sends the ink out through the blood stream Tattoo removal involves a series of pulses (laser beams) that hit the tattoo to disperse the ink into smaller particles. These particles
