    摘要: A sensing device projects near-field spatial modulations onto a closely spaced photodetector array. Due to physical properties of the grating, the point-spread response distributes spatial modulations over a relatively large area on the array. The spatial modulations are captured by the array, and photographs and other image information can be extracted from the resultant data. An image-change detector incorporating such a sensing device uses very little power because only a small number of active pixels are required to cover a visual field.
