摘要： A projection apparatus (18) forms an image frame (22) on a display surface (12), where the image frame (22) is a two-dimensional array of pixels. The projection apparatus (18) has a laser (40) light source, an image modulator (42) for forming an image-bearing beam according to scanned line data, and projection optics (44) for projecting the image-bearing beam toward the display surface (12). A camera (20) obtains a sensed pixel array by sensing the two-dimensional array of pixels from the display surface (12). A control logic processor (28) compares the sensed pixel array with corresponding image data to identify any portion of the image-bearing beam that is obstructed from the display surface (12) and to disable obstructed portions of the image-bearing beam for at least one subsequent image frame (22).

摘要： A monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated, line by line, from an electromechanical grating light modulator (85) and projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens assembly (100). To form each left and right intermediate image component, a separate image generation system (70) comprises a scanning ball lens assembly (100) comprising a spherical lens (46) for wide field of view and a reflective surface (102). A monocentric arrangement of optical components images the left and right scanning ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement with electromechanical grating light modulator (85) as a linear image source and scanning ball lens assemblies (100) provides an exceptionally wide field of view with large viewing pupil (14).

摘要： An autostereoscopic image display apparatus (10) that adapts to sensed feedback data about an observer (12) in order to conform its operation to adapt to the position and intraocular dimensions of the observer. The apparatus (10) uses ball lens projection optics to provide wide field-of-view pupil imaging, providing separate left- and right-eye images to the left and right eye pupils (14l,14r) of the observer (12), respectively. The apparatus (10) compensates for positional variables such as variable interocular distance and variable observer distance from projection optics. At least one observer feedback sensor (52) is disposed to provide feedback data about the observer (12). The feedback data can be used by a control logic processor (50) that, based on the data, adjusts left- and right viewing pupil forming apparatus (36l,36r). The control logic processor (50), based on sensed feedback data, may also vary image content or provide other stimuli such as smell, movement, and sound.

摘要： A head-mounted optical apparatus (10) providing pupil imaging with a very wide field of view. The head-mounted optical apparatus (10) employs a monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated and projected as left and right images from curved surfaces (68). For each right and left image, a ball lens assembly (30) is used to project a displayed intermediate image from the curved display surface (68) toward a beamsplitter (16), which directs an intermediate image toward the front focal surface of a curved mirror (24) that collimates the image to form a virtual image. The beamsplitter (16) transmits the virtual image for each eye to the observer.
