摘要： Speckle noise is reduced to increase image quality in an image display apparatus such as a projection display or the like.
An illuminating optical device in an image display apparatus (1) applies a laser beam L to a GLV (spatial modulator) (6) and modulates the laser beam based on an image signal input to the GLV to display an image. A plurality of laser beams (1, 1, ···) each having an optical path difference greater than the coherence length of the laser beam are applied to the GLV.

摘要： An optical scanning device (32) includes: a light projector (65) configured to radiate light while causing the light to make angular movement at a constant speed; and a light reflector (66) configured to reflect the light radiated from the light projector (65) to guide the light to an intended irradiated point on a predetermined scanning line (52). The light reflector (66) includes a plurality of reflecting portions (71, 72) and reflects, at least twice, the light radiated from the light projector (56) to guide the light to the intended irradiated point. The reflecting portions (71, 72) each include a plurality of reflecting surfaces (77, 78). A length of an optical path from the light projector (65) to the irradiated point is substantially constant for all of irradiated points on the scanning line (52), and a scanning speed, on the scanning line (52), of the light radiated from the light projector (65) is substantially constant.

摘要： Generally, the present disclosure describes a compact optical integrator that provides an increased path length for a beam of light in a compact projection system. The increased path length can improve the uniformity of the light passing through the compact projection system, with a minimal increase in the size of the system. The light can be homogenized by mixing light entering the integrator from different regions of the input area. The compact optical integrator can be positioned in the optical path between a light source and a spatial light modulator, such as a liquid crystal display (LCD) or a digital micro-mirror (DMM) array.

摘要： The invention relates to a small-size and light-weight optical system with an adjustable focal length. The invention relates to a method and system comprising an image plane (203, 303) on which there is formed an image of the target observed by the optical system, a first optical component (204, 304) with an adjustable focal length, and a prism (201, 301) with an optical path that is adjustable to correspond to the focal length adjusted for the first optical component (204, 304). By means of the optical system according to the invention, there is formed an image of the target under observation, located at the distance of the focal length of the first optical component (204, 304), on the image plane (203, 303) so that the first optical component (204, 304), the prism (201, 301) and the image plane (203, 303) remain permanently in place in relation to each other.

摘要： Described are a method and apparatus for high-speed phase shifting of an optical beam. A transparent plate having regions of different optical thickness is illuminated by an optical beam along a path of incidence that extends through the regions. The transparent plate can be moved or the optical beam can be steered to generate the path of incidence. The optical beam exiting the transparent plate has an instantaneous phase value according to the region in which the optical beam is incident. Advantageously, the phase values are repeatable and stable regardless of the location of incidence of the optical beam within the respective regions, and phase changes at high modulation rates are possible. The method and apparatus can be used to modulate a phase difference of a pair of coherent optical beams such as in an interferometric fringe projection system.
