Arrangement for detecting light sources |
摘要 |
An arrangement which enables the presence in an observed field of a light source whose radiation spectrum is known to be detected with a high signal to noise ratio. It includes an acousto-optical tunable filter controlled to scan through the expected spectrum of the source periodically and preferably linearly. The photo-detected signals are processed by a high-pass filter which removes the D.C. component due to ambient interference radiation and provides a periodic signal which correspond to the observed light source. The arrangement applies, in particular, to the angular location of luminous targets.
