Abstract

The signal-to-noise power spectrum, evaluated through point-spread-function profiling, is of general utility for assessing the quality of an optical system, with implications for most machine vision processors. Recently, this classic test has been applied to laser diode-based processors. In this paper we present empirical findings of the instrument noise spectra of such systems, and illustrate improvements in the instrument function given by various optimization techniques. The resulting low-noise system is used to evaluate the quality of components used in optical processors.
