Title:
TERAHERTZ PHOTODETECTOR, METHOD FOR DETECTING TERAHERTZ LIGHT, AND TERAHERTZ IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2006/064653
Kind Code:
A1
Abstract:
Disclosed is a terahertz photodetector comprising a first antenna (21A) for detecting a terahertz light (T2) polarized in a first direction (X direction), and a second antenna (21B) for detecting a terahertz light (T2) polarized in a second direction (Y direction) which is different from the first direction (X direction).
