Strela-10 optical proximity fuze

The 4 top "eyes" are optically connected to one single device in the middle, which seems to be some flavor of an arc light source. The 4 bottom eyes have a light sensor behind them. There must be electronics, buried deep in the middle.

Thanks for this photo, it will avoid me butchering my part to see inside. However mine seems a little bit different version, I have clamps instead of the large thread that can be seen on the roght side on your photo.
