Optical collimation material for fingerprint recognition under the smartphone screen

The material is a micron-scale two-dimensional optical waveguide array. It has excellent optical insulation properties between adjacent optical waveguides, and can autonomously select the reflected signal, allowing only valid fingerprint signals within a specific angle to pass through, eliminating excess background noise. The light is directly absorbed, and the valley ridges, blood flow and sweat glands in the fingerprint are clearly distinguished in the background. This product is mainly used in the fingerprint recognition technology under the smartphone screen, which realizes full-screen, fast, anti-glare unlocking recognition, and has completely independent intellectual property rights. At present, it has passed the batch assessment and verification of a number of mobile phones, and has attracted the attention of major mobile phone manufacturers.

Optical fiber imaging materials for intelligent security identification

The optical fiber imaging material for intelligent security identification developed by the company is composed of tens of millions of micron-scale optical fibers regularly arranged and fused. It has the characteristics of high resolution, large numerical aperture, and zero optical thickness, which can realize palmprint images. High-fidelity transmission. The material solves the urgent needs of the police, finance, government law enforcement and entry and exit management for a palmprint recognition system with large area, high resolution, high definition, low defect, and high cost performance, and provides key material support.
