Abstract

The invention belongs to the technical field of optical detection, and particularly relates to an optical axis consistency adjustment and detection device and method for a space laser communication terminal. According to the device, the offset of an optical axis is detected through a CCD detection camera, the CCD detection camera collects an image and can display the offset of a laser spot, the direction and the size of the optical axis are adjusted according to the displayed offset, the actual spot position is enabled to be coincide with the center of the theoretical spot position by adjusting the attitude of a to-be-detected optical system lens of the to-be-adjusted laser communication terminal, and the adjustment and detection process of the optical axis consistency is completed. The device is convenient and efficient to install and operate, high in adjustment precision and small in size, and the cost is greatly reduced.
