Abstract:
1. A stereoscopic display illuminator, comprising: a first light source for providing a first light beam; a curved mirror; a rotational wheel disposed between the first light source and the curved mirror, and comprising a first transmission segment and a first reflective segment; an actuator for rotating the rotational wheel, such that the first transmission segment and the first reflective segment of the rotational wheel are disposed on a path of the first light beam in sequence; a multi-band filter for allowing portion of the first light beam to pass through, and allowing another portion of the first light beam to be reflected, wherein the wavelengths of these two portions do not overlap; and an optical module disposed between the first light source and the rotational wheel for guiding the first light beam to the rotational wheel, and guiding the first light beam to propagate either from the first reflective segment or from the curved mirror to two opposite sides of the multi-band filter, such that the portion of the first light beam passes through the multi-band filter and reach a light emission position, and the another portion of the first light beam is reflected by the multi-band filter and reaches the light emission position.
