Abstract

See full text

An optical system comprises at least a source module comprising a non-uniform extended source (e.g., RGB-LED), an optical engine, and at least one of a lightpipe and a lenslet array arrangement. The optical engine is by example detailed at co-owned WO 2008/017718, and has a first toroidal ray guide and a second ray guide defining a common axis of revolution and having complementary imaging surfaces and pupils. For the case in which the system includes the lightpipe, such a lightpipe is disposed between the source module and the optical engine. For the case in which the system includes the lenslet array arrangement, the optical engine is disposed between the source module and the lenslet array arrangement. At least one ray guiding component, also detailed at WO 2008/017718, can be an alternative to the above optical engine. The lenslet array arrangement may include first and second lenslet arrays having corresponding lenslets.
