Title:
TERAHERTZ WAVE CAMERA AND DETECTION MODULE
Document Type and Number:
WIPO Patent Application WO/2019/116998
Kind Code:
A1
Abstract:
This terahertz wave camera 100 acquires information regarding an object to be measured 107 and comprises: a sensor unit 101 in which a plurality of elements 191 having spectral sensitivity to a terahertz wave 108 are arranged; a reading circuit unit 102 that reads signals from the elements 191; a first light-blocking section 103; and an optical section 103. The first light-blocking section 103 attenuates ambient light 111 to which the reading circuit unit 102 has spectral sensitivity. The optical section 103 guides the terahertz wave 108 from the object to be measured 107 to the sensor unit 101.
