在激光准直中的平直度、同心直线度的工程测量中,有一些测量工作要求速度快、操作简便,精度高。但目前一般非光电接收检测的激光准直仪器,都存在三个缺陷:一是都有一个约两米距离的盲区,在盲区内光束无法聚焦;二是测量时需要专人调整焦距;三是在十五米内准直精度只能达到0.25毫米,很难达到0.1～0.15毫米准直精度的要求。为了解决上述难题,烟台光学仪器厂青年工人王江民最近研制成功一种能在直线上连续
In the laser collimation of the straightness, concentric straightness of the engineering survey, some of the measurement requirements of fast, easy to operate, high precision. However, there are three defects in the conventional laser collimation instruments for non-optical receiving detection: one is that there is a blind spot with a distance of about two meters, the beam can not be focused in a blind spot; the other is that a person needs to adjust the focal length when measuring; Accuracy within fifteen meters can only reach 0.25 mm, it is difficult to achieve 0.1 ~ 0.15 mm collimation accuracy requirements. In order to solve the above problems, Yantai Optical Instrument Factory Wang Jiangmin young workers recently developed a success in a straight line
