Abstract:
1. A high-resolution imaging system for scanned column projectors, comprising: a column modulator configured to produce a time-varying line image; a collimator configured to receive and collimate the time-varying line image in at least one plane, wherein the column modulator is further configured to produce an intermediate image located in a back focal plane of the collimator to enable the collimator to reimage the intermediate image near infinity and wherein the intermediate image is comprised of a plurality of differently colored line images and each of the plurality of differently colored line images are sized differently to assist in correction of residual chromatic aberration in the final image; a scan mirror operable to receive and scan the collimated line image; and at least one imaging element configured to shape the scanned collimated line image onto a surface having a predetermined shape associated with the at least one imaging element.
