摘要：An optical system for a head-worn computer may include a light sourcepositioned within the head-worn computer and adapted to project non-polarizedilluminating light towards a partially reflective partially transmissive surface such that the

illuminating light reflects through a field lens and towards a reflective display and apolarizing film adjacent to a surface of the reflective display that polarizes the

illuminating light after it passes through the field lens. The illuminating light reflects off asurface of the reflective display, forming image light which is then analyzed by thepolarizing film prior to being transmitted through the field lens and then through thepartially reflective partially transmissive surface to a non-polarizing lower display opticalsystem adapted to present the image light to an eye of a user wearing the head-worncomputer.
