Photodiodes: Stability and Reliability
Photodiodes: Position Sensing Detectors
- Position Sensing Detectors and Photodiodes, General Discussion (324k)
Silicon photodetectors are commonly used for light power measurements in a wide range of applications such as bar-code readers, laser printers, medical imaging, spectroscopy and more. There is another function, however, which utilizes the photodetectors as optical position sensors. They, are widely referred to as Position Sensing Detectors or simply PSD’s. in one and two-dimensional configurations. - Using Photodetectors for Position Sensing (380k)
Electro-optical systems are increasingly used in position sensing and in dynamic measurements that require noncontact sensors with wide frequency bandwidth. - AN08 Lateral-Effect Photodiodes (252k)
Mechanical- Alignment applications of electro-optical instruments have expanded dramatically during the past three years in the construction, machine tool, aircraft and aerospace industries, increasing demands for new types of postition-sensing detectors. - AN10 Practical Electro-optics Deflection Measurements System (252k)
This paper describes an electro-optic displacement system which measures both angualr and lateral displacements simultaneously. - AN12 Continuous position sensing series (LSC, SC) (232k)
These series are sensitive, linear, and fast siliconphotodetectors that provide two electrical output signals, specifying the X only position(LSC Series) or X and Y position (Dual Axis SC Series) of an input right spot signal that is relativeto fixed internal coordinates. - AN13 Non-contact Optical Position Sensing using Silicon Photodetectors (508k)
The purpose of this paper is to examine the various types of silicon photodetectors, which may be used for position sensing. - AN15 Real time Bio Mechanical Position Sensing Based on a Lateral Effect Photodiode (108k)
The photodiode is a 1cm x 1cm device that is capable of sensing light imaged on its surface. - Quadrant and Bi-cell Silicon Photodiode Amplifier Module (128k)
