摘要

The analysis of a patented optical beam deflector based on a rotating prism is presented. It is shown that because of the transmissive, as opposed to reflective, nature of the proposed deflector, the resulting scan spot is for all practical purposes completely free of the tracking error that is so problematic to all reflective-type deflectors. In addition, if a conical scan is either acceptable or desirable, the scan lens design will be much simpler because the f - theta condition is not required and the scan field is inherently flat.
