Class Information
Number: 382/211
Name: Image analysis > Pattern recognition > Template matching (e.g., specific devices that determine the best match) > Spatial filtering (e.g., holography) > With electrically controlled light modulator or filter
Description: Subject matter wherein the spatial filtering unit comprises an electrically, or electronically controllable light modulator to impart an amplitude or phase modulation onto light passing through or reflected by the modulator.
