    摘要： An image output device of the disclosure facilitates enlargement of a stereoscopic image and includes a spatial light modulator, an image irradiation unit, and an address light irradiation unit. The spatial light modulator includes a main surface, a back surface, and pixels, reflects light emitted to the main surface, and modulates a phase of the light for each pixel. The image irradiation unit irradiates the main surface with light including an optical image. The address light irradiation unit irradiates the back surface with address light including a diffraction grating pattern. Each pixel of the spatial light modulator changes a phase modulation amount according to the intensity of the address light from a back surface. The address light irradiation unit dynamically change a diffraction grating pattern's direction on the back surface. The image irradiation unit irradiates the main surface with the optical image corresponding to the diffraction grating pattern's direction.

    摘要： A projector includes a lens, a beam processing module, a plurality of digital micromirror devices, a reflecting module and an illumination module. The beam processing module is disposed with respect to the lens. The digital micromirror devices are disposed around the beam processing module, wherein a beam projecting path is defined between the lens and the digital micromirror device. The reflecting module is disposed with respect to the digital micromirror devices and located beyond the beam projecting path. The illumination module is disposed with respect to the reflecting module. An initial beam projected by the illumination module is reflected to the digital micromirror devices by the reflecting module, such that the digital micromirror devices generate a plurality of image beams. The beam processing module combines the image beams to form a projecting beam and projects the projecting beam onto the lens along the beam projecting path.

    摘要： An optical aperture multiplier includes a first optical waveguide (10) having a rectangular cross-section and including partially reflecting surfaces (40) at an oblique angle to a direction of elongation of the waveguide. A second optical waveguide (20), also including partially reflecting surfaces (45) at an oblique angle, is optically coupled with the first optical waveguide (10). An image coupled into the first optical waveguide with an initial direction of propagation at an oblique coupling angle advances by four-fold internal reflection along the first optical waveguide, with a proportion of intensity of the image reflected at the partially reflecting surfaces so as to be coupled into the second optical waveguide, and then propagates through two-fold reflection within the second optical waveguide, with a proportion of intensity of the image reflected at the partially reflecting surfaces so as to be directed outwards from one of the parallel faces as a visible image.

    摘要： The present disclosure provides methods and systems for image processing. The methods may include obtaining original projection data of a target subject. For each of at least one slice location of the target subject, the methods may include generating a plurality of candidate slice images of the slice location based on a plurality of distance-weight relationships and the original projection data. Each of the plurality of distance-weight relationships may indicate a weight of a portion of the original projection data acquired by the radiation source and a distance from the radiation source to the slice location when acquiring the portion of the original projection data. The methods may further include generating at least one target medical image of the target subject based on the plurality of candidate slice images of each of the at least one slice location.
