Acoustic Surface Wave Devices for Visible and Infrared Imaging

Abstract

The objective of this research is the conception, development, and critical evaluation of a new class of devices employing the nonlinear interaction of acoustic surface waves (ASW) and photo-excited charge carriers to achieve rapid-scan optical imaging. The device operating principles are to be demonstrated initially through the use of silicon; however, a major objective is to obtain imaging with infrared radiation using narrow bandgap semiconductors. The experimental effort involves both separate medium and monolithic device configurations.
