Description

technical field [0001] The present invention relates to an optical three-dimensional recognition device, in particular to a device and a method for realizing correlation recognition based on three-dimensional microscopic and optical three-dimensional correlation recognition of tiny objects (length, width and height less than 2mm×2mm×0.1mm) based on integrated imaging. Background technique [0002] The optical correlation recognition method has the advantages of fast speed, high accuracy, non-contact, parallel processing and translation invariance, which make it widely used in the field of object recognition. Among them, the integrated imaging method does not require a coherent light source, which makes its structure simple and its anti-interference ability stronger. It can solve the problem that the optical system is difficult to realize the recognition of three-dimensional objects, and will have more practical significance and practical value. For example, in the field of m...

Problems solved by technology

This method requires fluorescent labeling of the sample, and can only passively acquire 3D information, which cannot reflect the advantages of integrated imaging that can record 3D information of objects in a single imaging, and cannot perform real-time 3D information processing

The above-mentioned devices have the defects of low magnification ability, poor imaging quality, less three-dimensional information obtained, and inability to obtain subtle features of the sample.
