Sensor for measuring the angle of rotation having at least dual rotatable code disc with at least dual optics

摘要

The invention relates to an angle of rotation sensor comprising a rotatable first code disc, at least one first image sensor and at least one optics which images an optical code of the code disc onto the first image sensor.

主权项

1. An angle of rotation sensor comprising a rotatable first code disc (2), at least one first image sensor (8) and at least one optics (18), the at least one optics imaging an optical code (14) of the code disc (2) onto the first image sensor (8),
further comprising at least one second rotating code disc (4), the at least one second rotating code disc (4) being either directly or indirectly rotatably connected to the first code disc (2) with a transmission ratio, with an optical code (14) of the second code disc (4) being imaged onto the first image sensor (8) by means of a second optics (20).
