Position Sensing with Photodiodes
ثبت نشده
چکیده
Position sensing photodiodes are detectors that provide quantitative information about the position of an incident light beam or spot image. There are currently two technologies that offer this functionality: multi-element photodiodes and position sensing (or lateral displacement) photodiodes. This article reviews the construction and operation of both types, discusses key considerations for optimizing their performance, and briefly examines some representative applications.

High-power RF photodiodes and their applications
There has been an increasing interest in photonic generation of RF signals in the millimeter-wave (30GHz ∼ 300GHz) and/or terahertz-wave (0.1 THz ∼ 10THz) regions, and photodiodes play a key role in it. This paper reviews recent progress in the high-power RF photodiodes such as UniTraveling-Carrier-Photodiodes (UTC-PDs), which operate at these frequencies. Several approaches to increasing both ...
متن کاملFully-Integrated CMOS biochip array for multicolor biomolecular diagnostics
Overview. The research objectives of this grant are focused on the development of biomolecular (DNA and protein) fluorescent-based sensing in complementary-metal-oxidesemiconductor (CMOS) devices. As part of this effort, we have developed two distinct fluorescence-based sensor chips, one based on conventional photodiodes and charge integration and the second based on Geiger-mode avalanche photo...
متن کاملSSC13-VIII-1 On-Orbit Calibration of Photodiodes for Attitude Determination
This paper presents a method for on-orbit calibration of photodiodes for sun sensing in an attitude determination system. The calibration estimates the scale factors and alignment angles of the photodiodes, resulting in higher attitude determination accuracy than achieved with the pre-flight calibration parameters. The calibration is implemented with an extended Kalman filter to simultaneously ...
متن کاملCharacterization of CMOS Photodiodes for Image Sensor Applications
N-well photodiodes and N+-diffusion photodiodes are available from standard CMOS processes. The comparison of quantum efficiency and dark current density for both structures have been described. The N-well photodiodes showed higher Quantum Efficiency (Q.E.) and lower dark current density than the N+-diffusion photodiodes. The photodiode capacitance is another important parameter. It determines ...
متن کاملComparison of the current of UV ray radiation on PIN Silicon photodiode and Gallium Arsenide
The high-energy UV ray radiation on PIN Silicon photodiodes reduces the optimal parameters of these photodiodes. In this paper, by representing a model, we compare the effect of UV dose on the bright current in these two types of photodiodes and confirm the analytic relationships in order to simulate a model with the help of the Silvaco- Atlas software. In this model, Silicon photodiodes and Ga...
