Abstract

A technology of spectrally adaptive light filtering has been demonstrated, which allows changing the transmission curve of an optical filter in an octave-wide spectral interval with the kilohertz rate under full computer control. This technology utilizes the unique capability of acousto-optic tunable filters to transmit light in several spectral intervals simultaneously, driven by radio signals with complex spectra. A computer algorithm to synthesize the driving signal for an arbitrary given spectral transmission curve was developed. This algorithm has been used for various applications of this developed technology in the visible, SWIR, and MWIR spectral intervals.
