1. Overview of Iris Recognition Technology
Rainbow vein pattern is a unique pattern formed at the junction of the colored circular area and the white scleral tendon in the human eye. By collecting and comparing these patterns, individual identity authentication can be achieved.

2. Diagnosis and Comparison of Rainbow Vein Patterns
Capture color images in the eyes through high-definition cameras and extract feature information from them. Then compare and match the extracted feature information with the templates stored in the database.

3. Application field
Iris recognition chips have a wide range of applications in the fields of security, finance, and smartphones. In the field of security, iris recognition chips can be used for identity authentication, access control systems, and monitoring systems, etc; In the financial field, rainbow vein technology can improve the security and convenience of payments; In smartphones, rainbow vein technology can replace traditional password unlocking methods.

4. Development and challenges
With the continuous advancement of technology, rainbow vein pattern diagnosis and comparison algorithms have also been continuously optimized. In the future, we can expect higher precision, faster speed, and more reliable rainbow pattern diagnosis and comparison systems. However, there are still some challenges in promoting the application of this technology, such as privacy protection issues and compatibility issues.

Summary: This article provides a detailed explanation of the acquisition and processing of rainbow pulse infrared images, and explores their application prospects and development trends in various fields. At the same time, some challenges faced by this technology were also pointed out.
