Imaging system of off-axis optical field

Abstract

The invention relates to an imaging system of an off-axis optical field. The imaging system of the off-axis optical field sequentially comprises an off-axis reflection subsystem, a micro-reflection mirror array and an optical sensing device along the imaging optical path, wherein the off-axis reflection subsystem comprises at least one optical device containing a reflection curved surface, and atleast one adjusting mechanism which is matched with the corresponding optical device with the reflection curved surface; the imaging optical path passes through the optical device with the reflectioncurved surface; each adjusting mechanism is used for adjusting the optical device with the reflection curved surface.

Description

technical field [0001] The present application relates to the field of optics, in particular to an off-axis light field imaging system. Background technique [0002] The definition of light field can be traced back to the definition given by Faraday in 1846, which refers to the amount of light passing through each point in each direction, expressed by a seven-dimensional function, P(Vx,Vy,Vz ,θ, λ,t). Based on this definition, later scientists simplified it into the 5D plenoptic function for us, using the function P(Vx,Vy,Vz,θ, ), however, the five-dimensional function is still difficult to reconstruct, and finally it is simplified to the four-dimensional light field theory again, expressed by the function P(u,v,x,y), and the full-light field camera we see today is based on this theory from the research results. This technology is used in cameras, bringing about a revolution in camera technology. [0003] Light field imaging systems have been recorded in the prior art...

AI Technical Summary

Problems solved by technology

[0004] 1. The optical distortion is large, and the optical lens will have different degrees of distortion due to the influence of its structure

[0005] 2. Dispersion, because the refractive index of different wavelengths of light in the same medium is different, it will cause dispersion problems

[0006] 3. The secondary spectrum, for a long focal length lens, the focal length is longer, the secondary spectrum has a large chromatic aberration, and the clarity and resolution of the photo will be reduced

[0007] 4. Energy loss, because the energy will be lost after the light passes through different media, and the final image quality will be reduced

[0008] 5. The preparation is complicated. In order to avoid some problems, the optical lens is generally composed of multiple lenses, so the preparation process is complicated

[0009] 6. The cost is high, because the small error of the optical lens will lead to the decline of the imaging quality, the cost of the current optical lens is generally high
