Problems solved by technology

In this way, although the size of the stereoscopic image is enlarged, the observer can only see a small part of the entire stereoscopic image due to the smaller viewing angle, which is also impractical

Abstract

The invention relates to a coherent three-dimensional display device based on optical wave-front reconstruction, comprising an optical wave-front generator and a first micro lens array plate. The optical wave-front generator is used for generating high-precision conjugate light waves in a small range so that the conjugate light waves are reversibly spread to the first micro lens array plate based on a light path and three-dimensional images are reconstructed in a big range in the sky after the conjugate light waves are focused and scattered by the first micro lens array plate. The first micro lens array plate is used for receiving the conjugate light waves generated by the optical wave-front generator; each micro lens focuses to generate a light cone to increase an observation angle of the three-dimensional images reconstructed based on a light path reversibility principle so that large-size and large-viewing angle three-dimensional display is realized.

Description

technical field [0001] The present invention relates to the fields of three-dimensional imaging and optical wavefront reconstruction, and more specifically relates to a coherent three-dimensional display device based on optical wavefront reconstruction, which is suitable for three-dimensional display, virtual reality, computer man-machine exchange, robot vision and other fields. Background technique [0002] Optical systems for 3D stereoscopic display can be classified into incoherent 3D stereoscopic display systems and coherent 3D stereoscopic display systems according to whether the light source used is an incoherent light source or a coherent light source. The two basic characteristics of light waves are amplitude and phase, where the amplitude reflects the brightness information, while the phase reflects the spatial position and shape information. The biggest difference between the incoherent 3D stereoscopic display system and the coherent 3D stereoscopic display syst...
