Abstract

In order to test the effectiveness of spatial diversity averaging as a method of reducing laser image speckle, an experimental 10.6-micron active imaging breadboard was constructed and used for obtaining day and night distant images at ranges exceeding one kilometer. The system was unusual in its use of employing dual acoustic-optic units for both generation of optical local oscillator signal and for beam combining of object reflected power and local oscillator power in an optical heterodyne detection system.
