Optical detection system, device, and method utilizing optical matching

An optical detection system and method detects movement of an optical pointing device in a data processing environment. The system works with any surface than can diffusely scatter a collimated beam from a coherent light source. Specifically, the system comprises a coherent light source and an optical sensing assembly. The optical sensing assembly comprises a plurality of photosensor arrays and a plurality of optical elements. Each photosensor array includes pixels of a particular size and shape. Each optical element has an artificially limited aperture and is associated, through optical matching, with a respective photosensor array. The coherent light source generates a collimated beam that is diffusely reflected off of the surface. The optical sensing assembly receives the diffusely reflected, or scattered, collimated beam and passes it through the artificially limited apertures of the optical elements to the associated corresponding photosensor array. Passing the scattered light through the optical elements generates speckle images that appear on the pixels, of the photosensor arrays. Based on the pixel shape, a pixel value associated with the speckle image provides a speckle image data signal. When there is translation of the pointing device, a new set of speckle images, each reassembling to a translated version of the previous speckle image, are generated and another speckle image data signal is generated. The new and the previous speckle image data signals are then used in a motion detection analysis to determine the points of the two data signals that give a displacement value.

Vein imaging apparatus, positional displacement interpolation method, and program

An imaging element of a vein imaging apparatus includes a vein image data generation region generating image data of a vein based a near-infrared light that was condensed by a lens array and that was scattered in a living body and transmitted through the vein and a positional displacement detection data generation region that includes a shielded section in which pixels are shielded from the light and an opening section in which pixels are not shielded from the light, and generates data for detecting positional displacement that is used to detect, based on the light received via the opening section, variation in an image focus position according to an imaging temperature. The vein imaging apparatus detects the image focus position of the light and estimates the amount of positional displacement occurred in the apparatus. The vein imaging apparatus selects a pixel based on the obtained amount of positional displacement.
