Abstract
In a specimen identification system, an oscillator directs a THz wave toward a channel that accommodates a specimen. A receiver detects the THz wave transmitted through the specimen. A first controller controls the oscillator to sweep the oscillation frequency of the THz wave within a frequency band. A receiver generates a receiving signal by sweeping the receiving frequency of the THz wave within the frequency band. A specimen identification unit specifies the specimen based on the waveform of the receiving signal within the frequency band.
Claims10
A specimen identification system comprising:
- a device including
- an oscillator generating a THz wave,
- a channel comprising a waveguide and accommodating a specimen, the specimen being irradiated with the THz wave, and
- a receiver receiving the THz wave and generating a receiving signal, the THz wave being transmitted through the specimen or being reflected on the specimen;
- a first controller controlling the oscillator to sweep an oscillation frequency of the THz wave within a frequency band;
- a second controller controlling the receiver to sweep a receiving frequency of the THz wave within the frequency band;
- and
- a specimen identification unit that specifies the specimen based on a waveform of the receiving signal within the frequency band.
A specimen identification device comprising:
- an oscillator generating a THz wave by sweeping an oscillation frequency of the THz wave within a frequency band;
- a channel comprising a waveguide and accommodating a specimen, the specimen being irradiated with the THz wave;
- and
- a receiver provided so as to sandwich the channel with the oscillator and receiving the THz wave, the THz wave being transmitted through or being reflected on the specimen, the receiver generating a receiving signal by sweeping a receiving frequency of the THz wave within the frequency band.
