Image sensing device and focal plane array device using frequency conversion for real-time terahertz imaging

摘要

Provided is an image sensing device that includes a detector configured to detect a terahertz wave signal received by a receiving antenna, a voltage-controlled oscillator configured to output an oscillation frequency according to an output voltage of the detector, and a frequency digital converter configured to convert the oscillation frequency output from the voltage-controlled oscillator to a digital signal.
