Solution Overview

Problem

Current image recognition devices can only emit light in a single direction, which limits their ability to recognize multiple pieces of image information on holograms at different angles or directions.

Innovation Solution

The device features multiple light sources circumferentially mounted on a circuit board, providing multiple light emitting directions, and an imaging component with a circular or columnar linear array lens to uniformly image light from these sources, allowing for recognition of images at various angles.

Solution Approach 1:

The patent divides the lighting system into multiple independent light sources (at least three) arranged circumferentially around the optical axis. Each light source can be independently controlled to emit light in different directions, enabling the system to capture hologram information from multiple angles. This segmentation allows the device to overcome the limitation of single-direction light emission while maintaining manageable complexity through modular design.
