1. A terahertz wave detection apparatus comprising:
a terahertz wave transceiver including a transmitter configured to transmit a terahertz wave and a receiver configured to receive a reflected terahertz wave reflected by a background object which exists behind an object to be analyzed;
a display;
an information processing apparatus connected to each of the terahertz wave transceiver and the display; and
a camera,
wherein
the transmitter irradiates a terahertz wave based on a transmission signal including a specific frequency toward a two-dimensional area including the object,
the information processing apparatus includes:
an analyzer configured to analyze an amount of change in a spread of distribution of the object based on the reflected terahertz wave; and
a visualizer configured to generate a display image according to the amount of change in the spread of the distribution based on the analysis result of the analyzer, and
the visualizer is further configured to display the display image on the display in accordance with a background image captured by the camera.
