Abstract :
The paper reveals a unique design for a narrowband tunable optical filter employing acousto-optic technology. The filter provides tuning capability over the entire blue-green spectral region within one second. The design configuration offers maximum economy, remarkable versatility, uniform spectral response and constant narrow bandwidth less than 0.3 nm. The proposed filter architecture uses state-of-the art technology and components to meet the tuning speed and resolution requirements
