光学自动准直依托于光学的基础理论两点一线的原理,通过两块反射镜进行平移和角移的调节,可以完成一段光路的准直调节,光学自动准直就是使该调节过程自动化。激光光路的自动准直是一闭环控制系统,如图1所示。放电泵浦MOPA系统光路较为复杂,为了确定自动准直的实际方案,选取单路予放大输入、输出作为研究对象。对角多路编码光束在放大器中的放大,光束传输方向决定了几何填充和能量提取水平,保证光束按预定方向通过放大器至关重要;而在像传递方面,希望像面位置不发生变化。
Optical auto-collimator relies on the principle of two-point and one-line of the basic theory of optics. The collimation and translation of a light path can be completed by two mirrors for translation and angular displacement. Optical auto-collimation automatically automates the adjustment process. Automatic alignment of laser light path is a closed-loop control system, as shown in Figure 1. The optical path of the discharge pump MOPA system is more complicated. In order to determine the actual scheme of auto-collimation, we choose single channel to amplify the input and output as the research object. Amplification of the diagonally multiplexed code beam in the amplifier, the direction of the beam transmission determines the level of geometric packing and energy extraction, and it is crucial to ensure that the beam passes through the amplifier in a predetermined direction. In the case of image transfer, it is desirable that the image plane position does not change.
