Abstract: The authors describe the dynamic behavior of position sensitive detectors. Earlier work has described the PSD response to changes in light intensity. Here, we investigate the PSD response to a change of light spot position. We call the linear filter describing this response the PSD transfer function (PTF).

The PSD General Response Function
TL;DR: In this article, the general response of a 1D position-sensitive detector (PSD) is derived by solving the Lucovsky equation in a fully general way, and the response indicates that a PSD is a decaying photocurrent accumulator, both in space and time domains.

A New Semiconductor Photocell Using Lateral Photoeffect
J. Torkel Wallmark
- 01 Apr 1957
TL;DR: In this paper, a photocell is described that uses the lateral effect and can detect the position of a light spot to less than 100 A. The sensitivity of the cell is approximately 200 microamperes per lumen and its frequency response is about the same as that of junction transistors.

Photoeffects in Nonuniformly Irradiated p‐n Junctions
TL;DR: In this paper, a theoretical basis is provided for the interpretation of photo effects observed in non-uniformly irradiated p−n junctions, and differential equations describing the junction photovoltage are developed through an application of the continuity and diffusion equations.

Lateral photodetector operating in the fully reverse-biased mode
TL;DR: In this article, the effect of background illumination on a reverse-biased lateral photodetector is considered and an ac equivalent circuit for the device is derived, from which the transient response is calculated and device parameters that determine its characteristics are presented.
