上海市激光技术研究所、上海第二光学仪器厂、上海电建施工技术研究所等单位共同研制的高精度激光准直仪于1988年10月29日通过了上海市的市级鉴定。鉴定全由市科委副主任陈祥禄主持,王之江研究员任鉴定组长,上科院四十多名专家出席会议。该准直仪采用了单机光束伺服技术,使仪器具有精确度高、稳定性好、使用方便等性能。在激光准直方面用伺服技术补偿大气漂移,具有创造性。该仪器光束方向漂移在40米处每小时不
Shanghai Laser Technology Institute, the second optical instrument factory in Shanghai, Shanghai Electric Construction Technology Institute and other units jointly developed by the high-precision laser collimator on October 29, 1988 passed the municipal appraisal in Shanghai. Appraisal by Chen Xianglu, deputy director of the Municipal Science and Technology Commission presided over, Wang Zhijiang Ren appraisal team leader, the Shanghai Academy of Sciences more than 40 experts attended the meeting. The collimator uses a single beam servo technology, so that the instrument has high accuracy, good stability, easy to use and other properties. In the laser collimation servo technology to compensate for the drift of the atmosphere, creative. The instrument beam direction drift at 40 meters per hour not
