心理和生理视觉研究用图象合成器的研制

An Apparatus of Image Synthesizer for Physiological and Psychophysical Vision Research

图象合成器由二路独立的图形发生器、图象旋转电路、二维矩形或圆形窗口、电路、ｘ轴Ｙ轴光栅扫描电路及Ｚ轴合成调辉电路组成。可以产生各种静止的、运动的光栅图形，满足视觉心理、生理研究工作所需的复杂刺激图形的要求。

The principle and a practical apparatus of digital image synthesizer are described in this paper.The system is composed of two independent digital image generators,image rotator circuits,two-dimentional rectangular and circular window circuits,raster generators and brightness modulating circuits.the image generator can produce varierty of images such as stationary or movig circular,annular,rectangular apertures,gratings and on a cathode ray tube screen.It meets the needs of pattern stimuli required for physiological and psychophysical vision research.
