A stereoscopic imaging method and device of a planar optical waveguide loop, the imaging method comprising the steps of: converting the coherent light emitted by a coherent light source into a two-dimensional point light source array, the position of each point light source in the two-dimensional point light source array being randomly distributed; discretizing a stereoscopic image into a large number of voxels and dividing the voxels into multiple groups according to the voxel brightness in descending order; for each voxel in each group, calculating the amount of phase adjustment of a point light source according to the distance of the voxel to the point light source, such that the light wave emitted by each point light source is in phase when reaching the voxel; accumulating the required amount of complex amplitude adjustment of each point light source for generating each voxel, driving the amplitude regulator and phase regulator of each point light source, and generating each group of voxels based on constructive interference. The imaging device consists of a coherent light source (1), a planar optical waveguide loop (2), a conductive glass front panel (3), and a back drive circuit (4), and can be widely used in the fields of computer and television three-dimensional display, three-dimensional human-machine interaction, and robotic vision.
