STEREOSCOPIC DISPLAY ILLUMINATOR AND STEREOSCOPIC DISPLAY DEVICE

摘要

A stereoscopic display illuminator includes a first light source, a curved mirror, a rotational wheel, an actuator, a multi-band filter, and an optical module. The first light source is used for providing a first light beam. The rotational wheel is disposed between the first light source and the curved mirror. The first light beam is reflected and passes through the rotational wheel in sequence. The multi-band filter allows portion of the first light beam to pass through, and allows another portion to be reflected, where the wavelengths of these two portions do not overlap. The optical module disposed between the first light source and the rotational wheel is used 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.

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.
