Considering the widespread application of infrared technology in military, security, medical, and other fields, improving the transmission quality and reliability of infrared system signals has become an urgent problem that should be solved. In this study, the application of temperature compensation technology in infrared systems for packet loss is investigated. A method is proposed for detecting packet loss via asynchronous triggering judgment, and systematic analyses, measurement, and verification are performed. This study provides a new solution and technical method for improving the signal transmission quality, signal integrity, and reliability of infrared systems.
