photodetector

(foh-toh-di-tek -ter) Any electronic device designed to respond to, i.e. detect, photons of light or other radiation. Examples include the photomultiplier and CCD.

photodetector

[¦fōd·ō·di′tek·tər]
(electronics)
A detector that responds to radiant energy; examples include photoconductive cells, photodiodes, photoresistors, photoswitches, phototransistors, phototubes, and photovoltaic cells. Also known as light-sensitive cell; light-sensitive detector; light sensor photodevice; photodevice; photoelectric detector; photosensor.

photodetector

A device that senses light. It uses the principle of photoconductivity, which is exhibited in certain materials that change their electrical conductivity when exposed to light. See photoelectric, photocell and photodiode.

To solve this issue, angle diversity based optical photo detector is proposed to mitigate the LOS interference.
This photo detector allows PASCAL to constantly test and monitor the laser power coming from the output beam.
The SP8053 features 20 photo detector elements, 130MHz RF and fast channel bandwidth and 10ns settling times.
Because they are open-ended, no distortion is introduced into the path of an infrared light beam and there is no interference with the reception of a photo detector. Plus, intrusive refracted light is reduced from entering the photo detector diode when the black-colored mount is used.
Its major components are a laser diode, a photo detector diode array, beam shaping and splitting optics, and a voice coil controlled lens that can be moved up and down for focus and sideways for fine tracking control.
Since the sensitivity of beam detectors is proportional to the distance between the source and the photo detector, it is difficult to fit a useable beam inside a single smoke alarm for residential use.
There, a photo detector converts the light into an electrical signal, and a microprocessor performs a spectral analysis, which indicates the level of octane and MBTE present in the sample.
The most common channelizer of this type is a laser, which uses a Bragg cell and photo detector outputs as shown in Figure 3.
This system will implement the application of photo cells as a photo detector to absorb the illumination of LED and turn it into electricity.
"A large part of why we are doing this is not to invent a photo detector, but to understand the processes involved in controlling carbon nanotube devices," said Leonard.
Nanotech firm Planet82 Inc., Seoul, Korea, announced its Single Carrier Modulation Photo Detector (SMPD), which uses nanotechnology to enable cameras to take high-resolution photos or video in the dark--without a flash.
Sipex Corporation (NASDAQ:SIPX), has debuted the SP8053, a photo detector IC specially designed for DVD and CD writers that utilize twin laser modules.
