| titleOfInvention | High resolution image projection system and method using a laser |
| abstract | (57) [Summary] An image projection system employing a microlaser and / or a diode laser array (11). Each laser in each array is individually addressable. The system includes three linear laser arrays, red (12), green (13) and blue (14) respectively, each individually addressable laser being powered and modulated according to an input image signal (21). To be done. When a laser diode pump energized microlaser array is used, the laser diode pumps are formed into an equivalent array (15, 16, 17). The laser output beams are combined in a dichroic prism (31) and reflected from a rotating multi-faceted scanning mirror surface (22) that performs two-dimensional scanning as it rotates. The image beam reflected from the scanner passes through the image lens (24) and the speckle eliminator (25) and reaches the projection screen (27). The invention further includes a method of generating and scanning an image beam, a novel speckle eliminator, and a microlaser array configured to ideally close spaces to achieve the desired result. In one embodiment, the laser diode pump is directly modulated with the video signal, and in another embodiment the microlaser output is modulated using a spatial light modulation array. |
