Acoustically read pulsed image converter

Abstract

An optical image scanner which employs a piezoelectric delay line and transversal interrogation scheme is proposed. Linear scanning with a resolution of 16 lines/in. and a sensitivity of 35 μW/cm2 have been achieved in a preliminary model. Estimates of limiting performance indicate the possibility of monolithic fabrication and resolutions in the region of 300 lines/in. using existing technology.
