IMAGING METHOD AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/153969
Kind Code:
A1
Abstract:
In the present invention, with respect to a one-time mask pattern generated by a spatial modulating element, pixels of a mask image projected onto a target object are shifted by only a set distance, by turning on one light-emitting point of a light source, or sequentially two ore more thereof. The pixel shift amount of the mask pattern is determined by the position of the light-emitting points of the light sources that are turned on, and are known. A mask image corresponding to a plurality of mask patterns dependent on the position of the light-emitting points of the light sources and the spatial modulating element is projected onto the target object. A computer constructs an image of the target object by calculating the correlation between a light intensity detected by a detector and the mask image projected onto the target object. The foregoing provides an imaging device and an imaging method which can increase the speed of mask pattern projection in single pixel imaging, and can greatly increase the input speed of single pixel imaging.
