| 摘 要： | 本文通过对红外相机的光机结构、成像介质TDICCD的工作原理、成像原理的简单描述.从光学成像,机械装调的角度出发介绍了一种红外相机的像面标定方法,即相机通过离轴反射式平行光管对黑体上的目标直接成像,通过观察与CCD相连的示波器显示的电信号的幅值强弱来判定是否调准像面.经实际应用证明,该标定方法是一种切实可行的方法,适用于实际工程.

| Abstract: | The optical-mechnical structure of an infrared camera and the operation principle of an Time Delay Integration(TDI) CCD are described in brief.A calibration method for the image plane of an infrared camera is presented in the aspects of optical imaging and mechanical adjustment.In the method,the object on a blackbody is imaged directly by using the infrared camera via an off-axis reflecting collimator.Then,whether the image plane is aligned is determined by the amplitude of the electric signal displayed on ... |
