Abstract

The invention relates to a laser three-dimensional imaging simulator, belongs to the field of three-dimensional imaging simulators, and aims to overcome the defect that the simulation distance cannot be flexibly adjusted in the prior art. The laser three-dimensional imaging simulator comprises a laser, an optical fiber array coupler, an optical fiber array, a liquid crystal spatial light modulator, a spatial filtering optical system, an aperture diaphragm and a tested system, wherein the optical fiber array consists of optical fiber bundles with increasing lengths; the aperture diaphragm is arranged on a focal plane of the spatial filtering optical system; a light beam emitted by the laser is projected to the optical fiber array coupler after being collimated, and enters the optical fiber array after being decomposed; emergent light of the optical fiber array is collimated and then projected to the liquid crystal spatial light modulator; in the light beams output by the liquid crystal spatial light modulator, the light beam passing through the aperture diaphragm is projected to a tested system after being collimated. One application of the invention is the design and manufacturing of the laser three-dimensional imaging simulator.

Description

technical field [0001] The invention relates to the field of three-dimensional imaging simulators, in particular to a laser three-dimensional imaging simulator. Background technique [0002] The prior art such as CN1085357388 discloses a three-dimensional close-range imaging simulator, which uses optical fiber discs of different lengths to simulate optical signal delays at different distances. However, the aforementioned documents cannot flexibly adjust the simulation distance, but set fixed lengths of 41m, 55m, 69m, 83m, and 89m optical fibers. If you want to change the simulation distance, you need to remodel the device and readjust the fiber length so that the device cannot Suitable for a wide range of application scenarios. Contents of the invention [0003] An object of the present invention is to solve the defect that the prior art cannot flexibly adjust the simulation distance. [0004] According to the first aspect of the present invention, a laser three-dimensio...
