Abstract: A photogrammetry system includes a photogrammetry rig and a plurality of cameras. The photogrammetry rig includes a support frame and a plurality of support arms. The support frame includes a plurality of joint members and a plurality of struts each extending between two of the plurality of joint members to collectively form a spherical polyhedron shape having a center focal point. Each of the plurality of support arms extends through a different one of the plurality of joint members in a direction following a different radial ray from the center focal point. Each of the plurality of support arms is selectively, linearly slidable and securable relative to the different one of the joint members along the different radial ray between a position closest to the center focal point and a different position farthest away from the center focal point. Each camera of the plurality of cameras is secured to an end of a different one of the plurality of support arms nearest the center focal point within the spherical polyhedron shape.

Abstract: A three-dimensional imaging system relies on effective native image resolution reduction in order to provide an array of pixel clusters, or voxels, with each pixel of the voxel representing a pixel of the image from a unique viewing angle. A 16-megapixel screen having 16-pixel voxels results in a screen having an image capacity downgraded to a 1-megapixel screen capable of showing sixteen different viewing angles. The system can be set up as a rear-projection screen or as a reflective screen illuminated by a front projector. The invention is best implemented with projectors and screens that represent all colors at a single physical location, such as a 3-panel LCD color-combinant projector or a DLP projector, either single or triple chip type. When the RGB sub-pixels are non-coincident, the viewers will see color artifacts that detract from the viewing experience.

Abstract: A light source system using an excitation light source and a multi-segmented color wheel device with wavelength conversion materials is disclosed. The color wheel device includes a first area having two or more first segments and a second area having two or more second segments for receiving the excitation light. The color wheel device is driven by the driving device periodically, so that a first light sequence is generated by the two or more first segments in the first working mode and a second light sequence is generated by the two or more second segments in the second working mode. The first light sequence is different from the second light sequence. The first and second working modes are switched by a switching device. The light source system may be used in image projection system generating two or more different lights sequences in different working modes.

Abstract: A projector includes: an optical element including first and second regions and which diffuses light that has entered the regions; an irradiation device for irradiating the first and second regions with light in a time-divisional manner; a polarization control unit disposed on a plane which is conjugate to a plane on which the optical element is disposed; and a spatial light modulator disposed in a light path from the optical element to the polarization control unit and which is illuminated with light that has been diffused by the first and second regions. The polarization control unit is configured to control the polarization state of light so that light that has been diffused by the first region becomes light of a first polarization component, and light that has been diffused by the second region becomes light of a second polarization component which differs from the first polarization component.

Abstract: An autostereoscopic display device includes a projector, an angle-enlarging module, a screen, and a polarization selector. The projector provides a lamp image unit with a first polarization state. The angle-enlarging module includes a deflecting plate, a wavelength retarder, and a polarizer. The deflecting plate has a first deflecting segment and a second deflecting segment alternately with each other. The first and the second deflecting segments respectively deflect the lamp image unit to a first direction and a second direction different from each other. The wavelength retarder has a transmitting segment aligned to the first deflecting segment and a wavelength retarding segment aligned to the second deflecting segment. The transmitting segment maintains the first polarization state when the lamp image unit passes therethrough. The wavelength retarding segment converts the first polarization state into a second polarization state. The polarization selector is disposed between the projector and the angle-enlarging module.
