Remote photoelectric sensors used for remote sensing contain only the optical components of a sensor. The circuitry for power input, amplification, and output switching is located elsewhere, typically in a control panel. This allows the sensor, itself, to be very small. Also, the controls for the sensor are more accessible, since they may be ...
A rear reflector on a bicycle Reflecting device on horse. A safety reflector is a retroreflector intended for pedestrians, runners, motorized and non-motorized vehicles. A safety reflector is similar to reflective stripes that can be found on safety vests and clothing worn by road workers and rescue workers. They are sometimes erroneously ...
A bicycle reflector appears brighter to the passenger car driver than to the truck driver at the same distance from the vehicle to the reflector. [1] The light beam and the normal axis of the reflector as shown in Figure 2 form the entrance angle. The entrance angle is a function of the orientation of the reflector to the light source.
The Dam Safety Interest Group of CEA Technologies, Inc. (CEATI), a consortium of electrical power organizations, has applied Spread-spectrum time-domain reflectometry to identify potential faults in concrete dam anchor cables. The key benefit of Time Domain reflectometry over other testing methods is the non-destructive method of these tests.
Large integrating sphere for measurement on light bulbs and small lamps. An integrating sphere (also known as an Ulbricht sphere) is an optical component consisting of a hollow spherical cavity with its interior covered with a diffuse white reflective coating, with small holes for entrance and exit ports.

An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs: [1] [2] [3] One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, [4] [5] used an infrared LED and a four-quadrant infrared sensor to ...
