Application of intensity interferometry for terahertz passive imaging is discussed. The intensity interferometry is famous for the first demonstration by Hanbury-Brown and Twiss, while image reconstruction was not possible due to lack of electromagnetic phase information. Using wide bandwidth detector system, precision delay-time measurement is obtained and aperture systhesis imaging can be realized. We introduce our microwave experiment of astronomical intensity interferometer and discuss their application to terahertz imaging.
