工作原理：working principle:

发射端：激光器常亮，电机带动圆反射镜旋转，经特制光路反射后实现来回扫描。Transmitter: The laser is always on, and the motor drives the circular mirror to rotate, and scans back and forth after being reflected by a special optical path.

反射点为圆反射镜几何中心，圆反射镜逆时针旋转，至a位置(图4所示)时反射光通过缝隙，对目标区域进行从右至左的扫描。此后反射光被遮挡，旋转至b位置时旋转圆反射镜反射光受长方体反射镜二次反射，实现对目标区域从左至右的扫描。The reflection point is the geometric center of the circular mirror. The circular mirror rotates counterclockwise. When the circular mirror reaches position a (as shown in Figure 4), the reflected light passes through the slit and scans the target area from right to left. Afterwards, the reflected light is blocked, and when it is rotated to position b, the reflected light of the rotating circular mirror is reflected twice by the cuboid mirror to realize scanning of the target area from left to right.

接收端：接收端硅光二极管受激光照射时输出微弱电压，经二级放大后输入单片机。单片机记录每两次接收到信号的时间间隔，根据其数值所处范围判断自身所处位置区域，发出控制指令，使电机带动接收装置向中间区域移动，直至回正。Receiving end: When the silicon photodiode at the receiving end is irradiated by laser light, it outputs a weak voltage, which is input to the single-chip microcomputer after secondary amplification. The single-chip microcomputer records the time interval of receiving the signal every two times, judges the area where it is located according to the range of its value, and issues a control command to make the motor drive the receiving device to move to the middle area until it returns to normal.

电机带动圆反射镜旋转，两次扫描之间时间间隔远大于有效信号间隔。接收端位置偏左与偏右时所测得时间间隔不同，从右至左逐渐增大，故可设定中间1/3范围为中心位置，测得结果大于此范围则使电机向右移动，小于则向左。The motor drives the circular mirror to rotate, and the time interval between two scans is much longer than the effective signal interval. The measured time interval is different when the position of the receiving end is to the left and to the right, and gradually increases from right to left, so the middle 1/3 range can be set as the center position. If the measured result is greater than this range, the motor will move to the right. Less than to the left.

以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
