JG-Ⅱ型自动补偿激光干涉仪是为了在工作现场对各种移动式工作台进行精确定位及精密测量长度而设计的。它体积小,便于现场移动。尤其是采用了气温、气压传感器能自动补偿工作现场环境而引起的测量误差。与用折射率干涉仪补偿法相比较:具有不需真空装置,省去了抽空时间,便于现场使用等特点。该仪器的主要技术指标如下:1.仪器在0～20米内可以稳定可靠工作;2.分辨率:0.1μ;3.测量精度:在计量室恒温车间使用时
JG-Ⅱ automatic compensation laser interferometer is designed to accurately locate and precisely measure the length of various mobile workbenches on the working site. It is small, easy to move on site. Especially the use of temperature, pressure sensors can automatically compensate for the work site environment caused by the measurement error. Compared with the refractive index interferometer compensation method: with no vacuum device, eliminating the time to take the time for easy on-site use and so on. The main technical indicators of the instrument are as follows: 1. The instrument can work stably and reliably within 0 ~ 20m; 2. Resolution: 0.1μ; 3. Measurement accuracy: When using in the measuring room constant temperature workshop
