太空中單個衛星之間是通過光信號進行通訊的。因此需要一個可以自動調節角度的鏡面傾斜系統,以確保一個衛星發出的光信號能夠正對且持續穩定地達到另外一個衛星的接收系統。為了實現對鏡面傾斜角度的閉環控制,核心的問題是通過非接觸位移傳感器準確測量鏡面角度。為此目的,米銥公司提供高精度電渦流傳感器系統,小巧的外形尺寸使該傳感器可以方便地集成到整個系統當中。
In the communication between individual satellites fast mirror tilting systems are employed which use laser light as the carrier medium. The application of these mirrors enables the laser beam of the optical transmitter to be exactly aligned on the receiver and the direction to be kept stable during the transmission. The core of the closed-loop control system for the mirror tilting systems are displacement sensors which determine the exact positional values via the mirror movement. For this application MICRO-EPSILON supplies extremely high resolution eddy current systems in miniature versions which are integrated into the overall system.
