Title:
ALL-SOLID-STATE HOLOGRAPHIC PHOTOGRAPHING DEVICE AND ALL-SOLID-STATE HOLOGRAPHIC PROJECTOR
Document Type and Number:
WIPO Patent Application WO/2021/143640
Kind Code:
A1
Abstract:
An all-solid-state holographic photographing device and an all-solid-state holographic projector. The all-solid-state holographic photographing device comprises a photographing lens group (1) and an imaging unit (2) which are provided inside the holographic photographing device, the photographing lens group (1) is used to capture light rays of a scene, and the imaging unit (2) comprises multiple photosensitive chips (21); light rays of the scene at image planes of different depths of field is optically converted by the photographing lens group (1) and the imaging unit (2), and then real image pictures at image planes of different depths of field of the scene are formed on photosensitive chips (21) at corresponding distances and are recorded, the distance between adjacent pixels forming the real image pictures on the photosensitive chips (21) is d (mm), the multiple photosensitive chips (21) are equivalent to a group of equivalent photosensitive surfaces (3) parallel to each other corresponding to the photographing lens group (1), and the distance between any two adjacent equivalent photosensitive surfaces (3) is L (mm), wherein L≥2d. By means of the solution of introducing multiple equivalent photosensitive surfaces (3), the function for photographing a real 3D image is realized, and no moving component is required, greatly improving the reliability and image quality, and also reducing the production cost and the control difficulty.
