Patent ID: 8872114

Claim:
An inspection apparatus that inspects a photo device, said inspection apparatus comprising: an irradiation part that irradiates said photo device with pulsed light; and a detecting part that detects an electromagnetic wave pulse, which is generated by said photo device according to said pulsed light irradiation, wherein said detecting part includes: a detector that detects electric field intensity of said electromagnetic wave pulse according to irradiation of probe light emitted from a light source of said pulsed light; and a delaying part that delays detection timing at which said detector detects said electromagnetic wave pulse by changing a temporal difference between a time said electromagnetic wave pulse reaches said detector and a time said probe light reaches said detecting part, the inspection apparatus further comprising a time waveform constructing part that constructs a time waveform from electromagnetic wave intensity of an electromagnetic pulse detected by the detector at said plurality of pieces of detection timing.
