Introduction
The AOTF instrument acquired by Penn State University during fall 1995 was used for several experiments geared towards applications development. Various tests were conducted to evaluate the performance and characterize the filter response of the instrument. This report outlines some of the work done at Penn State along with the working principle of the AOTF.
This AOTF instrument was developed by Prof Vladislav I. Pustovoit of the Institute of Radio Engineering & Electronics of the Russian Academy of Sciences in Moscow. lt is an electronically tunable filter in the region 400-800 mn. The accuracy of the filter is very high ( < 5 Å) and dependent only on the quality of the acoustic control signal applied to it. This provides a very repeatable narrowband filter capability with a spectral resolution of 1.5-2.0 Å.
