Description

Measurement of PPD (Pixelated Photon Detector) characteristics with various wavelengths is important for understanding and improvement of the sensor performances. We have developed a new pulsed laser microscope system whose wavelength is continuously tunable from 410 nm to 2200 nm by using OPO laser system. Laser spot can be focused to ~2 um, small enough to measure pixel-by-pixel performance of PPD. In this workshop, new multi-wavelength measurements of various types of PPDs using the laser microscope system will be reported.
