Default Re: Television over a light beam

Way back in the 1990's I was involved with a project that evolved sending video via a infra-red link. When nobody was looking I opened the receiver box and found a IR photo diode typical of the type used in television remote control a few years earlier, and focused with a big Fresnel lens. The system worked Ok except at sunrise, when, because the receiver was looking to the east, sunlight saturated the diode.
Living in Nottingham, I'm going to pop along on Saturday.
