精密数字式光学星点传感器的发明和试验,已经证明有可能得到高度精确的星点座标位置,而不管星点是处在传感器视场内的那一个位置上。 一般所说的“跟踪”,就只要求用一个数字指令近似地代表星点视线来随动一个望远镜就行了。这跟踪器从误差链排除了随动系统不完善调零的影响。对数字光学的技术来讲,这里座标的数据形式本来就是数字式的。
The invention and experimentation of precision digital optical star sensors have demonstrated that it is possible to obtain highly accurate positions of the star coordinates regardless of the position of the star in the field of view of the sensor. The so-called “tracking” simply requires that a telescope be followed by a numerical command that approximately represents the line of sight of the star. This tracker eliminates the effects of imperfect zeroing of the servo system from the error chain. For digital optics, the coordinate data format here is inherently digital.
