Abstract

In this paper is presented an operation concept of sine wave and square wave correlation mode for the scannerless laser 3D imaging system based on opto-electric correlation range array implemented with a gain-controllable image intensifier. The intensity of light source is sinusoidally modulated while the gain of image intensifier is squarely modulated by means of gating photocathode. The equality of sine-square wave correlation mode with the dual sinusoidal wave correlation mode is shown. The simplicity and feasibility of photocathode gating method is demonstrated.
