Objective: Study on the technology of revealing the latent marks on poker surface by optical methods. Methods: Using the blue and green light as the excitation light irradiation the latent marks on poker surface(60 samples) respectively, observe and photographed the latent marks through the red and orange Long pass filter. Results: This optical method has been successfully used in revealing latent marks on poker surface, 60 samples of the latent marks on poker surface appeared. Conclusion: The Photoluminescence technology can reveal the latent marks on poker surface effectively.
