Acousto-optic tunable filter wavelength selectivity measurement method

Abstract

Acousto-optic tunable filter (AOTF) wavelength defines the device ability to process and transmit information. Although this parameter is the most important for AOTF spectrometric applications, it also plays an important part for AOTF providing multispectral processing of images. Hence, it is necessary to provide AOTF selectivity measurements by such way the information possibilities of the device would be strictly characterized by the measured value. This method has been developed and listed in the presented work. The theoretical basis of this method as well as its experimental implementation of the presented method is discussed. It has been found that the only AOTF selectivity beforehand admissible probability of information unit loss.
