PSD modules contain a high-precision PSD (Position Sensitive Detector) and a low-noise amplifier, and are able to perform accurate distance
measurement. C10442 series uses a one-dimensional PSD, and C10443 series uses a two-dimensional PSD. Using a PSD module with a
dedicated signal processing unit (C10459 or C10460) allows obtaining distance information easily.
