Abstract
Devices, systems, and methods for measuring and determining positions of light energy having wavelengths of less than (as well as equal to or greater than) 200 nm, and are particularly well suited for measuring pulsed light at ultraviolet and other wavelengths using position sensing diode (PSD) technology. An integrator may sum a total charge of a signal from the PSD. Correlations between a distribution of integrated charges among electrodes of the PSD may be non-linear, and may benefit from adjustment for different overall pulse light quantities and/or spot sizes.
