Technical Field

[0002] In fields such as aerospace, military reconnaissance, environmental monitoring, and industrial automation, the performance testing and calibration of various optoelectronic detection devices (ultraviolet flame detectors, visible light cameras, etc.) are crucial. Traditional testing methods typically employ real light sources or field experiments, which have many drawbacks, such as high cost, poor controllability, insufficient flexibility, and safety issues. Existing light source simulation devices are available, but most are single-function, either only simulating a single wavelength of light and failing to meet the testing requirements of multi-spectral optoelectronic devices. Therefore, a multi-band signal simulation system is needed. Summary of the Invention
