The invention discloses a non-vision-field correlated imaging method based on a
chaotic optical comb, and relates to the technical field of computational imaging. The correlated imaging
system provided by the method is composed of a
chaotic optical comb source, a two-dimensional dispersion projection module, a single-
pixel detector, a time-distance correlation module and a second-order correlation reconstruction module. A random
optical frequency comb is generated by using a
silicon nitride micro-ring, multi-point random illumination is formed through VIPA and a
grating, an
echo time sequence is recorded through a
single pixel, a virtual
voxel is constructed in combination with
flight time, and a three-dimensional image of a hidden target is reconstructed at a time through second-order correlation operation. According to the invention, high-speed and high-efficiency non-vision-field three-dimensional imaging can be realized without mechanical scanning or a
spatial light modulator, and the method is suitable for scenes such as complex environment detection, post-disaster search, corner
perception in unmanned driving and the like.
