A position sensitive device and/or position sensitive detector (PSD) is an optical position sensor (OPS) that can measure a position of a light spot in one or two-dimensions on a sensor surface. Principles
In IKI and IPM, Gruntman worked on position-sensitive detectors on the basis of the microchannel plates [6] and techniques for the detection of energetic neutral atoms (ENA imaging) in space. [7] [8] [9] Later he participated in ENA experiments on the NASA IMAGE, [10] [11] TWINS [12] and IBEX [13] missions.
Modern day atom probe tomography uses a position sensitive detector aka a FIM in a box to deduce the lateral location of atoms. The idea of the APT, inspired by J. A. Panitz's Field Desorption Spectrometer patent, was developed by Mike Miller starting in 1983 and culminated with the first prototype in 1986. [4]

A time projection chamber consists of a gas-filled detection volume in an electric field with a position-sensitive electron collection system. The original design (and the one most commonly used) is a cylindrical chamber with multi-wire proportional chambers (MWPC) as endplates.
A hemispherical positively-biased fluorescent screen on which the diffraction pattern can be directly observed, or a position-sensitive electron detector. Most new LEED systems use a reverse view scheme, which has a minimized electron gun, and the pattern is viewed from behind through a transmission screen and a viewport.

Detector tubes The 128 linear position-sensitive 3 He gas detector tubes cover the full opening height of 300 millimetres (12 in) behind the collimators. They determine the position of the neutron event by charge division over the resistive anode towards each end of the detector. Overall and local count rates lie in the several 10000 Hz range.
