Patent ID: 7919752

Claim:
An inspection apparatus for conducting inspection of an object to be measured by using a terahertz wave, the inspection apparatus comprising: a terahertz wave generation portion; a terahertz wave detection portion configured to detect a terahertz wave applied from the terahertz wave generation portion to the object to be measured, the terahertz wave being detected through the object to be measured; a waveform shaping portion configured to shape a first answer signal with respect to the terahertz wave by using a signal acquired in the terahertz wave detection portion; a measurement condition acquisition portion configured to acquire a first measurement condition; an answer signal storage portion configured to store second answer signals associated with measurement conditions; a selection portion configured to select the second answer signal from the answer signal storage portion by using the first measurement condition; and a signal processing portion configured to conduct deconvolution with respect to the first answer signal on the basis of the second answer signal.
