摘　　要：陀螺经纬仪光电积分测量系统,在我国属首次研制,已获成功。本文论述了研制中光电检测器的线性度及电压稳定度、光强、陀螺马达的指向精度、悬带零位稳定性、系统温度漂移误差等几个关键问题的技术途径。实践证明,光电积分法测量,可以自动精密寻北;缩短了观测时间;增强了抗干扰能力,便于在野外和机动条件下使用。这种测量方法在陀螺经纬仪中具有普遍推广应用价值。This paper proposes a few important technical problems in precise gyrotheodolite with photo-electronic integral measuring system which has been developed for the first in China:1.The linearity of the sensor can be fractionated up to 0.3% by means of suitable test, so that the photo-electronic detecting was able to perform in the gyro- theodolite of high degree of accuracy.2.The precision circuit that whose stability is as high as 0.01% and the optical system with slanting reflector were designed,therefore,the stability of output give freedom from the operating voltage change of the sensor and the inadequacy of light intensity.3.Microconsumption direct current magneto was sc- leered to use and it can fulfil the requirement of the direction accuracy. 4. The design for stationary locking structure and the determination for the best locking position may stabilize efficiently zero position of the suspending tape 5.To make measuring system with double reflect- or to a considerable extent can decrease shift error.The practice de- monstrated that photo-electronic integral measuring method may find automatically accurate north and as compared with ordinary method its advandages are as follows,measuring time decreased,freedom from jamming rised,operation eased and so on.This method will be generally opplicable to the gyrotheodolite.
