摘要： Implementations of a compressive light field projection system are disclosed herein. In one embodiment, the compressive light field projection system utilizes a pair of light modulators, such as digital micromirror devices (DMDs), that interact to produce a light field. The light field is then projected via a projection lens onto a screen, which may be an angle expanding projection screen that includes a Fresnel lens for straightening the views of the light field and either a double lenticular array of Keplerian lens pairs or a single lenticular, for increasing the field of view. In addition, compression techniques are disclosed for generating patterns to place on the pair of light modulators so as to reduce the number of frames needed to recreate a light field.

摘要： A laser system for generation of three-dimensional (3D) colored images based on laser sources generating light at a plurality of wavelengths including basic color range (red, green and blue) that illuminate a two-dimensional display, at a given color range wherein a plurality of 2D images formed at different depths by image light impinges on a first optical element, with wavelength-sensitive focal length. All images of the given colored range are perceived by the human's eyes as a single 3D image of this color range. 3D images in red, green and blue that are formed at different positions, are fused by a second optical element, with adjustable focal length. As the light is switched between red, green and blue color ranges, the adjustable focal length is adjusted to compensate a change of the focal length of the first element, so the human's eyes see a fully colored 3D image.

摘要： A light-source module includes a light-source unit, a first projection lens, a first lens, a mirror wheel, a first light-guiding unit, a second light-guiding unit, and a second projection lens. The first projection lens has an entrance pupil. The light beam provided by the light-source unit can pass through the first projection lens via the entrance pupil and then is guided to the mirror wheel. With the rotation of the mirror wheel, when the light beam passes through the mirror wheel, it becomes a transmission light beam. At different time, when the light beam is reflected by the mirror wheel, it becomes a reflection light beam. The second projection lens has a first exit pupil and a second exit pupil, in which the transmission light beam and the reflection light beam pass through the second projection lens via the first exit pupil and the second exit pupil, respectively.

摘要： Disclosed herein are apparatuses and methods for reclaiming the full field of view (FOV) of the original camera lens in a stereoscopic image capture system using an anamorphic attachment. Also disclosed are apparatuses and methods of projecting stereoscopic images on a fixed size screen from a single projector that was initially designed primarily for 2D operation. An exemplary apparatus may comprise an anamorphic afocal converter configured to halve a FOV of a camera or projector into two optical paths, and convert the halved FOVs into two full FOVs of the camera or projector. Such an apparatus may further comprise reflecting elements cooperatively arranged to direct two rectified images at a camera sensor or projection screen, where one or more reflecting elements receive the first of the two full FOVs and one or more reflecting elements receive the second of the two full FOVs.

摘要： For an illuminated object projected onto a screen through an optical system having a single object lens, light reflected from the object reaches the object lens through right and left polarizers and wherein the polarizing crystals in each are oriented at right angles to those in the other. The projected image is viewed through a second pair of right and left polarizers, shown as eyepieces in frames to be worn as glasses. Due to the combined effects of the polarizers, the image seen through the eyepieces appears three dimensional.

摘要： According to one embodiment, an X-ray imaging apparatus includes an X-ray image acquisition unit, a control system and a display processing part. The X-ray image acquisition unit acquires X-ray image data of an object by using at least one imaging system. The control system controls the imaging system to acquire X-ray image data corresponding to different directions by reciprocating the imaging system repeatedly. The display processing part acquires X-ray image data for stereoscopic viewing out of the X-ray image data corresponding to the different directions to generate and display stereoscopically visible image data on a display unit based on the X-ray image data for the stereoscopic viewing. The X-ray image data for the stereoscopic viewing are acquired in a period without a motion or a possibility of the motion in an imaging part of the object.
