摘要： Provided is an aging degradation diagnosis circuit, including: a first delay circuit including a gate array for allowing aging degradation to progress, the first delay circuit being configured to delay an input signal and output a first output signal; a second delay circuit including a gate array having the same number of stages as the first delay circuit, the second delay circuit being configured to delay an input signal and output a second output signal; and an arbitrary delay unit, which is capable of varying a delay period in the second delay circuit by a predetermined amount. A delay comparison unit outputs comparison information obtained by relatively comparing delays between the first output signal and the second output signal. An adjustment unit uses the comparison information, to thereby readjust the delay period in the second delay circuit.

摘要： A high-resolution high-speed terahertz spectrometry for measuring a terahertz frequency spectrum at high speed with a laser mode-locking frequency which is the theoretical limitation frequency resolution of the terahertz time-domain spectroscopy. The mode-locking frequencies of two femtosecond laser light sources are controlled so that they are stabilized at high degree and the difference between the mode-locking frequencies is constant. The output of the laser light sources are used as a pumping light for generating terahertz pulses and a probe pulse light for terahertz detection. Since the time delay timings of the terahertz pulses and the probe pulse light the pulse periods of which are slightly different from each other shift from each other and the difference increases. Therefore, the temporally expanded terahertz pulses are measured by high-speed sampling without using any mechanical stage for time delay scanning. Part of the laser beams are extracted and time origin signals are generated by trigger signal generating means and used as trigger signals. Consequently the influence of the timing jitter can be eliminated. The terahertz electric field time waveform measured by high-speed sampling with the measurement time window of the pulse period is subjected to time-scale conversion and Fourier transform. Therefore, a terahertz frequency spectrum can be measured with high resolution of the theoretical limitation frequency resolution (=mode-locking frequency) and at high speed.
