Abstract

The invention discloses millimeter wave inspection equipment comprising optical devices (30,50,60) for receiving millimeter waves radiated by inspected objects and converging the received millimeter waves, a radiometer receiving device (80) for receiving the energy of the converged millimeter waves and converting the energy of the millimeter waves into an electric signal and an imaging device for forming temperature images of the inspected objects according to the electric signal. Compared with the prior art, the millimeter wave inspection equipment provided by the invention has a simple and compact structure; due to the adoption of a passive millimeter wave human body security inspection technology, the human body can not be hurt; and forbidden objects hidden in clothes of the human body can be inspected.

Description

technical field [0001] The invention relates to a human body security inspection device, in particular to a millimeter wave inspection device for human body inspection. Background technique [0002] Known human body security inspection equipment mainly includes metal detectors, trace inspection instruments, and X-ray transmission equipment. Specifically, metal detectors are only sensitive to detecting metallic substances. Trace detectors are only effective for detecting explosives and narcotics. X-ray transmission equipment detects metal / non-metal items, explosives, drugs, etc., and can have high spatial resolution and a certain scanning speed, but because the ionizing radiation of X-rays has certain harm to human health, Therefore, it is restricted for human security inspection. [0003] In order to realize the function of human body safety inspection, it is necessary to propose a millimeter-wave inspection device, which can at least effectively alleviate at least one of...
