Title:
PULSE SPECTROSCOPE
Document Type and Number:
WIPO Patent Application WO/2022/085568
Kind Code:
A1
Abstract:
The pulse width of light from a pulse light source 1 is stretched in a stretching element 2 so that the elapsed time in a pulse and the wavelength of the light correspond one-to-one and an object S is irradiated with the resulting light, and the output of a light receiver 4 that has received the light from the object S is digitalized by an AD converter 6 and fed to a computation means 5. A trigger signal generated by a trigger signal generation unit 7 in concert with the rise of the pulse light is delayed by a trigger delay unit 74 and fed to the AD converter 6, and the trigger signal is inputted after the end of a dead time T3.
