Abstract
Terahertz wave detection equipment comprises: a terahertz wave transceiver including a transmitter for transmitting a terahertz wave and a receiver for receiving a reflected terahertz wave reflected by a background reflected object which exists behind an object to be analyzed; a display; and an information processing apparatus, wherein the transmitter irradiates a terahertz wave based on a transmission signal including a specific frequency toward a two-dimensional area including the object to be analyzed, and the information processing apparatus is configured to analyze concentration of the object to be analyzed based on the reflected terahertz wave and generate a composite image in which a concentration image of the object to be analyzed is combined with an image of the background reflected object.
