摘　　要：光电摄像器用作微型计算机的传感器,对光学图像的光强进行数字化测量,其光电转换特性γ是一个重要参量.γ值不等于1,将会给测量结果造成很大的误差.本文描述了对γ≠1的摄像器进行非线性校正的新方法,并以应用实例作了验证.When a TV camera is used as a detector, the light intensity of the image can be mesured. But the nonlinear characteristic of a TV camera will give rise to serious deviations in experimental results. This paper describes a mathod and results for calibrating the nonlinear characteristic in the TV camera. Several examples show that the calibration is quite effective.
