Device and method for adjusting an optical rotary joint

摘要

The method involves using a coaxial collimator in one of units. The light is injected into the collimator. The distance of a light bundle axis (5) is measured from the rotary axis at two positions, which correspond to two different light path lengths. The tipping of the optical axis of the collimator is determined against the rotary axis and the distance of the light bundle axis is determined from the rotary axis by the data measured. The distance and the tipping between the light bundle axis and the rotary axis is minimized by moving or tipping the collimator. An independent claim is also included for a device for the adjustment of turnover carrier.
