Abstract
A rotating optical joint has two organs which are able to rotate independently of one other on a common axis (14). Collimators (18, 20) are mounted directly opposite one another on the organs, in an arrangement such that they permanently provide a variation of the power of the transmitted signal of less than 25%, during relative rotation of the said organs. The total number of collimators (18, 20) is preferably less than or equal to eight. Advantageously, three collimators (20) are mounted on one of the organs and four collimators (18) are mounted on the other organ.
