Verfahren und Vorrichtung zum Löschen eines externen Schnittstelleneffekts bei dem aktiven Spurnachlauf für eine optische Freiraumkommunikation |
摘要 |
System and a method for eliminating external light interference effects in an active tracking equipment for free space optics communication, wherein a sample of an incoming light is received by a quad cells device (3) which outputs quadrant components of voltage values indicative of deviations of the incoming (IL; IL1) beam in different directions. The output of said quad cells device is filtered by a high pass filter (5) for blocking DC components as well as frequency components lower than a predetermined value from the out of the quad cells device (3), the output of the filter (5) being indicative of the position of incoming light (IL; IL1) with respect to the receiver (1). <IMAGE> |
