FIELD: physics.
SUBSTANCE: optical-electronic converter has a hollow light guide consisting of a movable plate connected to a sensitive element and three fixed plates, a radiation source directed towards one of the plates, and a photodetector, wherein an optical beam from the radiation source propagates in the light guide on a broken spiral, which corresponds to the path of skew rays in light guides.
EFFECT: high sensitivity of equipment for receiving and amplifying signals without increasing overall dimensions.
