Abstract

Devices (10), systems, and methods for measuring and determining positions of light energy (12a, 12b) having wavelengths of 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 (26). An integrator (34) may sum a total charge of a signal from the PS (26). Correlations between a distribution of integrated charges among electrodes of the PSD may be non-linear, and may benefit fro adjustment for different overall pulse light quantities and/or spot sizes.
