A high-precision variable-beam divergence angle laser transmitter based on a digital control zooming collimator relates to a laser transmitter which realizes high-precision variable-beam divergence angle through a digital control zooming collimator. The invention solves the problems that the prior terminal test system can only provide a single light beam divergence angle and has poor testing capability. The laser of the invention is arranged on the travelling carriage of a one-dimensional precision displacement device; a digital control zooming collimator and a telescope are arranged at the laser transmitting port of the laser in turn; the central axial lines of the incident light of the digital control zooming collimator and the telescope coincide with the central axial line of the laser transmitting port of the laser; the input / output ends of both the one-dimensional precision displacement device and the digital control zooming collimator are connected with the input / output end of a control computer. The invention can realize variable light beam divergence angle and is suitable for the test of various link terminals and the performance parameters of various laser transmitting / receiving systems; moreover, the invention can improve tensing capability.
Description
technical field [0001] The invention relates to a laser emitting device, in particular to a laser emitting device which realizes a high-precision variable beam divergence angle through a numerically controlled zoom collimator. Background technique [0002] In the development process of satellite optical communication terminals, in order to test the performance of the optical communication terminal tracking system, a high-precision variable beam divergence laser emission system is required to simulate target terminals in different links. The existing terminal test system can only provide a single beam divergence angle, and the test capability is limited. Therefore, a laser emitting device with variable beam divergence is urgently needed in the development of satellite optical communication terminals. The parameter optimization design of the communication system is of great significance. Contents of the invention [0003] In order to solve the problem that the existing term...
