Abstract
A receiver according to an embodiment is a terahertz band receiver including an antenna configured to receive a terahertz band signal reflected or transmitted from a measurement target, a detector configured to receive a differential signal including a first input signal VTHz and a second input signal −VTHz with phase difference of 180° to each other from the antenna to detect a voltage, and operate in a concurrent mode, and a buffer amplifier configured to amplify and output a signal detected by the detector.

A receiver of terahertz band, comprising:
- an antenna configured to receive a terahertz band signal reflected or transmitted from a measurement target;
- a detector configured to receive differential signals including a first input signal VTHz and a second input signal −VTHz with phase difference of 180° to each other from the antenna to detect a voltage, and operate in a concurrent mode;
- and
- a buffer amplifier configured to amplify and output a signal detected by the detector.
An imaging system of terahertz band comprising:
- a transmitter configured to transmit a terahertz band signal to a measurement target;
- and
- a receiver configured to receive a signal reflected or transmitted from the measurement target, the receiver comprising:
- an antenna configured to receive the terahertz band signal reflected or transmitted from the measurement target;
- a detector configured to receive differential signals including a first input signal VTHz and a second input signal −VTHz with phase difference of 180° to each other from the antenna to detect a voltage, and operate in a concurrent mode;
- and
- a buffer amplifier configured to amplify and output a signal detected by the detector.
A detector mounted on a receiver of the terahertz band, wherein the detector is configured to receive differential signals including a first input signal and a second input signal with phase difference of 180° to each other from an antenna that receives a terahertz band signal, detect a voltage, and operate in a concurrent mode.
