Terahertz wave detection device, terahertz wave detection method, and terahertz wave detection system

A terahertz wave detection method comprising the steps of:

• irradiating a terahertz wave based on a transmission signal including a specific frequency toward a two-dimensional area including an object to be analyzed;
• receiving a reflected terahertz wave reflected by a background object which exists behind the object;
• acquiring a background image captured by a camera;
• analyzing an amount of change in a spread of distribution of the object based on the reflected terahertz wave;
• generating a display image according to the amount of change in the spread of the distribution of the object based on a result of analysis of the amount of change in the spread of the distribution of the object;
• and
• displaying the display image on the display in accordance with the background image.

A terahertz wave detection system 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 wearable terminal including a display;
• an information processing apparatus connected to each of the terahertz wave transceiver and the wearable terminal;
• and
• a camera,
• wherein
• the terahertz wave transceiver 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
