| 20100008625 | METHOD FOR DESIGNING OPTIMISED MULTI-CHANNEL GRATING STRUCTURES - A method is described for designing a multi-channel grating structure having at least one specified spectral characteristic in a photosensitive material, the multi-channel grating structure having at least one free spectral characteristic which is not a specified spectral characteristic. An initial value is provided for each free spectral characteristic, and an initial multi-channel grating function is provided that describes an initial multi-channel grating structure by applying a spectral to spatial domain algorithm to the specified predetermined spectral characteristic using the initial value. A target multi-channel grating function is provided which describes a target multi-channel grating structure in the photosensitive material and an updated value is determined for each initial value with reference to the spectral characteristics of the target multi-channel grating function. An updated multi-channel grating function is derived which describes an updated multi-channel grating structure in the photosensitive material by applying a spectral to spatial domain algorithm to the predetermined spectral characteristic using the at least one updated value. After at least one iteration, the updated multi-channel grating function is output to describe the multi-channel grating structure. | 01-14-2010 |

| 20080298644 | SYSTEM AND METHOD FOR CONTROLLING IMAGE QUALITY - An image quality control system and method is disclosed. At least one infrared camera takes a screen image of a room. When there are a plurality of cameras, images of the cameras are synchronized with respect to time, and a specific object of the image is tracked to estimate image quality of the object. When there are a plurality of cameras, a 3D screen model is reconfigured, and positions of the cameras and the infrared lighting tools are controlled. Infrared lighting and the cameras are controlled, and particularly, optical axis direction, optical magnification, exposure time, and the iris of the camera can be amended. Next, a high-quality object image list can be generated so as to process the images. | 12-04-2008 |
