Terahertz signal-based image collection device, image generation system and image generation method

Abstract

A terahertz signal-based image collection device, an image generation system and an image generation method are disclosed. The image collection device includes: a swinging reflection plate configured to reflect terahertz wave signals emitted from a sampling region including a target to be inspected; a lens component configured to focus the terahertz wave signals reflected by the swinging reflection plate; and a radiometer array including n rows of radiometers mounted on a focal plane of the lens component, where the n rows of radiometers are configured to sample the terahertz wave signals emitted from the same height of the target to be inspected and reflected by the swinging reflection plate at intervals, where n≥2, so that the formed terahertz wave image has higher resolution and higher contrast.

Dependencies are inferred from the claim text.
