Opto-electronic sensor for indicating direction.

摘要

The invention refers to an opto-electronic sensor that automatically and continuously tracks a punctiform light source that moves inside a given volume, and permanently indicates the direction in space of the light source. The sensor is made up of an opto-electronic sighting device (A), which generates an error signal when its axis does not coincide with the direction of a punctiform light source (S), the signal controls two positioning systems, one in the vertical plane (B) and one in the horizontal plane (C) respectively, which align the axis of the sighting device (A) with the direction of the light source (S) and when the error signal comes down to a minimum, two incremental rotary transducers (6 and 10) are used to determine the angles in the vertical and the horizontal plane that define the direction of the light source.
