The device includes a dual-type fusion holographic lensless imaging module and a neural network module. The dual-type fusion holographic lensless imaging module includes a laser source, a microhole , filter, first reflector, second reflector, first coherent light source, second coherent light source, target sample and glass slide, first CCD sensor, second CCD sensor, computer and moving slide rail, neural network The module consists of a position parameter optimization neural network and a target detection area convolutional neural network. The dual-type fusion lensless imaging module simultaneously obtains the imaging information of the transmission module and the reflection module, and finally fuses and reconstructs higher-quality imaging results. The network continuously optimizes the position parameters, further optimizes the imaging results, and finally predicts the results by the convolutional neural network in the target detection area, and outputs easy-to-understand and explicit evaluation results.

Description

technical field [0001] The invention relates to the technical fields of computational imaging, deep learning, and lensless microscopic imaging, and in particular to a lensless dual-type fusion target detection device and method based on deep learning. Background technique [0002] Nowadays, the problems of disease diagnosis, food safety testing and environmental pollution investigation in backward areas are becoming more and more prominent. The traditional optical microscope system makes the optical microscope increasingly expensive, cumbersome and difficult to maintain. Due to remoteness and lack of talents in backward areas, equipment and technology cannot be well promoted and applied. [0003] Lensless imaging technology is a new type of effective imaging microscopy technology developed in recent years: it does not use lenses to focus, but directly transmits the sample to the photodetector to record the image, and uses effective algorithms to reconstruct the clear image. ...
