JZB-800型激光准直仪有效地克服了微弱背景光的干扰,有利于全天进行准直并实现了自动跟踪数字显示。该仪器仅对光源进行调制,对接收器采取选频接收和自动搜索,接收靶用光栅技术作位移变送器,当靶头未接受到光信号时,自动扫描搜索激光中心;当对准激光中心后,由光栅数字显示仪显示测点波带板的位置。经724米、901米模拟位移试验,其观测精度分别为±0.20毫米和±0.29毫米;在薄雾或大气急剧
JZB-800 laser collimator effectively overcome the weak background light interference, is conducive to all-day collimation and automatic tracking digital display. The instrument only modulates the light source, the receiver adopts the frequency selective receiving and the automatic search, the receiving target uses the grating technology as the displacement transmitter, automatically scans the searching laser center when the target does not receive the optical signal; when the laser Center, the grating digital display instrument shows the location of the strip plate. The 724 meters, 901 meters simulation displacement test, the observation accuracy of ± 0.20 mm and ± 0.29 mm; in the haze or the atmosphere is abrupt
