Provided are a terahertz wave detection device and a terahertz wave detection system to execute checking at high speed with high sensitivity and accuracy and to execute omnidirectional inspection without requiring a large checking system. A flexible array sensor () includes: a terahertz wave detection element () having a flexible single-walled carbon nanotube film (), and a first electrode () and a second electrode () disposed to face each other on a two-dimensional plane of the single-walled carbon nanotube film (); and a flexible substrate () having flexibility to support the terahertz wave detection element () so as to be freely curved. The flexible substrate () is preferably formed in a curved or cylindrical shape, so that the terahertz wave detection elements () are arrayed on the flexible substrateformed in a curved or cylindrical shape.

Terahertz wave detection device and terahertz wave detection system

A terahertz wave detection device includes a low-dimensional electron system material formed on a substrate; and a first electrode and a second electrode opposingly arranged on a two-dimensional plane of the low-dimensional electron system material. The first electrode and the second electrode are made of metals having different thermal conductivity. An 8-element array sensor includes eight terahertz wave detection devices aligned in an array. The terahertz wave detection device includes carbon nanotube film; a first electrode disposed on one side of the carbon nanotube film; and a second electrode disposed on the other side of the carbon nanotube film. The first electrode and the second electrode have different thermal conductivity.

Terahertz wave detection device and array sensor

A terahertz image measurement device includes a terahertz detection sensor, a magnetic field generating unit, and a measurement control unit. The sensor detects near-field light of terahertz light emitted from a sample. The magnetic field generating unit has a coil disposed around the sample and the sensor, and wound to surround the optical axis of terahertz light irradiated on the sensor, and applies to the sensor a magnetic field generated by allowing an electric current to flow through the coil. The measurement control unit changes a value of the electric current flowing through the coil, sets a strength of the magnetic field to a magnetic field value for which a detection signal level of the terahertz light detected by the sensor increases prominently, and allows the magnetic field value to conform to a specific frequency of the terahertz light.
