Transparent optical element and method for adjusting light field to penetrate through transparent optical element

Abstract

The invention provides a transparent optical element and a method for adjusting a light field penetrating through the transparent optical element. The adjusting method comprises the following steps: S1, carrying out light field tracing on incident light entering a micro-lens array of the transparent optical element; s2, performing light field tracing on the first incident light field through emergent light of a micro-lens array of the transparent optical element; s3, the second incident light field penetrates through the crystalline lens of the observer and forms emergent light, the emergent light is tracked, and the emergent light passes through the retina of the observer and forms a projection light field; s4, obtaining the intensity of a light field distributed on the retina of the observer; and S5, according to the light field intensity distributed on the retina of the observer, obtaining the mean square error of the pixel intensity distribution of the retina of the observer, and performing optimization by taking the minimum value of the mean square error as a target. According to the invention, the randomly distributed micro-lens array is utilized to realize glare elimination based on the reflection principle, and a light field passes through the surfaces of the micro-lenses, so that the mirror reflection energy is greatly reduced, and the anti-glare effect is achieved.

Description

technical field [0001] The invention relates to the field of micro-nano optics, in particular to a transparent optical element and a method for adjusting a light field passing through the transparent optical element. Background technique [0002] Anti-glare is to reduce the specular reflection of the sunlight or light incident on the surface of the object through scattering or reflection, so that the reflected light entering the observer's glasses becomes less, so that the observer's glasses are not irradiated by strong reflected light. , to protect the eye health of observers, especially when using electronic screens that are becoming more and more popular. [0003] A large number of existing anti-glare implementation technologies are based on the use of micro-nano structures to scatter incident light. When light waves irradiate nanostructured particles, according to the Mie scattering theory, light waves will be scattered in all directions, so that the energy of light wav...

Problems solved by technology

[0005] The scattering of existing anti-glare micro-nano particles has the following disadvantages: First, the production is prone to uneven distribution of scattering particles. For high PPI, such as the display of mobile phone screens , it is easy to produce scattered points visible to the naked eye; second, the production cost is relatively high; third, due to the scattering effect of particles, the transmittance is low, etc.
