Advancements and Applications of Position-Sensitive Detector (PSD): A Review

Abstract:

This paper presents a review of the Position-Sensitive Detector (PSD) sensor, covering the different types of PSD and recent works related to this field. Furthermore, it explained the theoretical concepts and provided information about its structure and principle of operation. Moreover, it includes the main information about the available commercial PSDs by Hamamatsu, along with a comparison between the common modules. The PSD features include high position resolution, fast response, and a wide dynamic range. These features make it suitable for various fields and applications such as imaging, spectrometry, spectroscopy and others.
