Embodiment Construction

[0030] Such as figure 1 As shown, the multi-object simultaneous imaging and encryption method based on computational correlation imaging, the system includes a light source LS, a beam expander BE, a light modulation system DMD, a projection lens PL, a convergence lens CL, a single-pixel detector SP and a data acquisition system DA and computer system CP;

[0031] The light source LS emits light, and after passing through the beam expander BE, it irradiates the light modulation system DMD to produce illumination speckle, and then irradiates multiple objects after passing through the projection lens PL, and multiple objects are placed side by side, and the reflected or transmitted light of multiple objects is converged by the converging lens CL to the single-pixel detector SP, and then the data is stored and processed by the data acquisition and computer system. The main steps of its method are:

Abstract

The invention provides a multi-object simultaneous imaging and encryption method based on calculation correlated imaging. Independent measurement conducted on each object is not needed, and simultaneous imaging of multiple objects can be achieved only through one-time measurement and detection. In addition, the method further has information encryption capability. By adopting the method, the volume of data acquired by the system can be decreased, the imaging efficiency of a correlated imaging system can be improved. The method adopts an encoding matrix to encode information of the multiple objects. Therefore, compared with a traditional correlated imaging system adopting speckles or / detection strength as a secret key, the method provides a third secret key-encoding speckle, and accordingly the encryption performance of the calculation correlated imaging system can be improved.

Description

technical field [0001] The invention relates to the field of computational correlation imaging, in particular to a simultaneous imaging method for multiple objects based on a single measurement, and can encrypt information of multiple objects. Background technique [0002] Correlation imaging, also known as "ghost imaging", quantum imaging, etc., is widely used in remote sensing, biomedicine, and national defense, and has attracted the attention and research of many scientific researchers in recent years. The difference between computational correlation imaging and traditional correlation imaging is that computer preset random speckle is used to replace the reference arm in traditional correlation imaging (that is, the relevant light intensity distribution information is obtained by the area array detector), and the computer preset speckle The information is associated with the light intensity information collected by the single-pixel detector to obtain the image of the targ...
