Paper Abstract

We present details of an electronically tunable, narrow bandpass optical filter for applications in optical spectroscopy and spectral imaging. It is based on the combination of an acousto-optic tunable filter and a Fabry- Perot, which we call an acousto-optic Fabry-Perot filter (AOFPF). It offers advantages of a broadband tuning range (several hundred nanometers) and a narrow optical bandpass (subangstrom resolution in visible/NIR). A prototype AOFPF which operates in the visible/NIR wavelength region has been designed, fabricated and tested. Detailed experimental results are presented.
