cladding, which have different refractive indexes. The light beam travels through the core by repeatedly bouncing off the wall of the cladding. The light beam, having passed through the fiber without any loss in light quantity, is dispersed at an angle of approximately 60° and emitted to the...

Laser Radar:Figure 1 shows a MV351, a “Laser-Radar” system manufactured by Nikon Metrology, in which the laser beam is steered by rotating around horizontal and vertical axes. This unit sends a distinct, focused laser pulse to an object and reads the return signal as described above. Unli...
* They are useful in LED lighting fixtures for placement in living rooms and huge halls because of their wide-angle beam. * High lumens at night time are required in spaces such as a playground, gardens, or a large stadium. * Additional applications incorporate basic lighting for passageways...
In a home security system, you aim the beam at the light sensor, across a passageway in your house. When somebody walks between the light source and the sensor, the path of the beam is blocked briefly. The sensor registers a drop in light levels and sends a signal to the control box....
Light-emitting diode (LED).An LED display is a type of LCD that uses a set of LEDs as its light source, rather than the types of backlights (often cold cathode fluorescent lamps) used for LCD displays. LED technology is generally smaller and lighter than the original LCD. A newer type...
