Ultra high-speed real-time color calculation ghost imaging device and method

Abstract

The invention discloses an ultra high-speed real-time color calculation ghost imaging device and method. The device comprises a random speckle emission source, a lens, a point detector and a computer, wherein a to-be-imaged object is located between the random speckle emission source and the lens, the light emitted by the random speckle emission source irradiates a light sensitive surface of the point detector after passing by the to-be-imaged object and the lens, and a control end of the random speckle emission source and an output end of the point detector are connected with the computer; and the random speckle emission source is an LED array. By adoption of the device and method, the imaging of a high-speed moving target object is realized, the imaging distance range is relatively large, the imaging resolution is relatively high, the anti-disturbance ability is high, and the imaging speed is high.

Description

technical field [0001] The invention belongs to the field of target imaging detection, and relates to an ultra-high-speed real-time color computing ghost imaging device and method. Background technique [0002] The development of ghost imaging has gone through stages such as entangled two-photon ghost imaging, pseudothermal ghost imaging, true thermal ghost imaging, reflected light ghost imaging and computational ghost imaging. In 1995, Shi Yanhua's group at the University of Maryland first experimentally realized ghost imaging based on entangled two-photon pairs. In 2006, Scarcelli et al. used a classical pseudothermal light source to realize lensless thermal optical ghost imaging. Subsequently, Wu Ling'an's group used rubidium hollow cathode electron tubes as the light source to realize true thermal optical ghost imaging. Computational ghost imaging can realize super-resolution imaging and lens-free imaging, which has advantages that traditional imaging does not have. Ho...

Problems solved by technology

However, computational ghost imaging requires a large number of samples for correlation operations, so the imaging speed of traditional computational ghost imaging is relatively slow, and the final imaging frame rate is less than 10 Hz. Limited by the slow imaging speed, no one has performed ultra-high-speed computational ghost imaging before. Imaging Research
