摘要： A video imaging system is disclosed. The system is responsive to electrical signals introduced into it, which electrical signals represent an image. The system includes an acoustic-optical cell (31), the cell including an anisotropic medium for sound transmittal. The electrical signals are received, and optionally compressed (53), before being introduced into transducers (42) mounted on the cell. The transducers convert the electrical signals into sound waves which traverse the width of the cell. After substantially a full line of display of the image is travelling through the cell, a monochromatic light source (11), such as a metal vapor pulsed laser, is pulsed for a time duration less than the propagation time of a single pixel across or transverse to the sound signal in the cell. This modulates the monochromatic light which is then focused (63, 71) and displayed on a screen (81) at the appropriate position for the line of image.

摘要： A calibration apparatus calibrating a projection unit projecting light-rays includes: an imaging unit taking an image of a surface of an object having a location and an attitude, the light-rays projected onto the surface by the projection unit; a location-and-attitude estimation unit estimating the location and the attitude of the surface based on the image; a reflection-point estimation unit estimating, based on the estimated location and the attitude, a reflection point at which one of the light-rays is reflected by the surface; and an identification unit identifying both a passing point that the one of the light-rays passes and a direction in which the one of the light-rays passes the passing point, or identifying only the direction, based on multiple reflection points obtained by the reflection-point estimation unit with respect to multiple different locations and/or multiple different attitudes of the surface.
