摘要： An information acquisition apparatus includes a pulse generator 9, a detector 10, a first delay unit 15, a second delay unit 16 and a computation unit. The pulse generator 9 is excited by a first laser beam to generate a terahertz wave in the form of a pulse. The detector 10 is excited by a second laser beam coherent to the first laser beam to detect the terahertz wave from object 2 that is irradiated with the pulse of the terahertz wave. The first delay unit 15 changes the delay time in such a way that the detector 10 can detect the pulse signal of the terahertz wave from the object 2. The second delay unit 16 changes the delay time by not greater than the temporal width of the pulse signal detected by the detector 10. The computation unit computationally determines the information on the temporal position of the peak of the pulse signal of the terahertz wave from the object 2 according to the information of the signal detected by the detector 10 when the delay time is changed by the second delay unit within the delay time of the first delay unit.

摘要： An information acquiring apparatus includes a light source portion for generating pulse-shaped pump light, and first and second probe light in synchronization with each other. A generating portion generates terahertz pulses when irradiated with the pump light. A detecting portion detects pulses of terahertz radiation from the object. A first delay portion adjusts an optical path difference between optical paths of the pump light and the first probe light reaching the detecting portion, so that the detecting portion detects a field intensity of a fixed point on the time domain waveform of the terahertz pulse from the object, following the fixed point. A second delay portion adjusts an optical path difference between the optical path of the pump light and the second probe light reaching the detecting portion by a sum of an additional optical path adjustment amount and the optical path difference, so that the detecting portion obtains the time domain waveform. A correction processing portion compensates for influence of a change in condition of the object on the time domain waveform, using the field intensity of the fixed point, or the adjustment amount adjusted by the first delay portion.
