Electronic Instrumentation
The photoelectric transducers include photo-emissive, photo-conductive and
phot-voltaic transducers. In photoemissive transducers, when radiation falls on
cathode, electrons are emitted from cathode. While in photoconductive
transducers, ...

5.3 TYPES OF PHOTOSENSISTORS/PHOTODETECTORS Of the various types
of photodetectors, the commonly used ones are: (i) photoemissive cells and
photomultipliers, (ii) photovoltaic cells, and (iii) photoconductive cells including ...

Textbook on Optical Fiber Communication and Its Applications
5.2.1 Photoemissive Diode A semiconductor material of GaAs when exposed to
photon energy of hv, the photon is absorbed in the semiconductor and it gives its
energy to an electron. Similarly other photons are absorbed and give up their ...

Principles of Medical Electronics and Biomedical Instrumentation
The photoemissive tube consists of an evacuated or gas filled bulb with two
electrodes — one, the cathode on which is a coating of specially prepared
material that releases electrons when illuminated, and the other, the anode. The
coating ...

Handbook of Biological Confocal Microscopy
Photoemissive effects are used in simple vacuum phototubes composed of a
simple cathode and anode. They are very fast. They are also found in devices
that interpose gain, such as gas-filled phototubes that rely on the avalanche
effect of ...

Springer Handbook of Lasers and Optics
The operational principle underlying photoemissive detectors is the external
photoelectric effect, which is the emission of electrons from a surface upon
exposure to electromagnetic radiation. To amplify the signal detectors with
multiple ...

Sensors and Transducers
The photoemissive cell, in fact, was the dominant type of photosensor for many
years, and played a vital part in the development of cinema sound since it was
the transducer ¢rst used for converting the ¢lm soundtrack into audio-electrical ...
PHOTOEMISSIVE (VACUUM) TUBES This phototube consists of a
semicylindrical cathode and a wire anode sealed inside an evacuated
transparent envelope. The concave surface of the cathode supports a layer of
photoemissive material ...
