Abstract: The present disclosure provides a ray filter (10). The ray filter is arranged in front of an X-ray source and is switchable between a first state where the ray filter is configured to allow the high-energy X-rays and the low-energy X-rays to pass therethrough and a second state where the ray filter is configured to only allow the high-energy X-rays to pass therethrough. The present disclosure further provides a dual-energy X ray inspection system comprising a dual-energy X-ray source and the ray filter. The ray filter of the present disclosure has a small volume, a simple configuration, and is easily applicable to the dual-energy X ray inspection system without changing arrangement of the inspection system.
