PSD signal processing circuit
Digital output for connection with PC
C9068, C9069
PRELIMINARY DATA
Aug. 2002
C9068 (for one-dimensional PSD) and C9069 (for pin-cushion type two-dimensional PSD) are DC signal processing circuits specifically
designed for position measurement using PSD. Digital output allows direct connection with a personal computer through a serial (RS-232C)
interface. C9068 and C9069 are capable of detecting accurate positions of a spot light regardless of light intensity.
A D/A conversion signal is also output for monitoring, and when a voltmeter is connected to this D/A conversion output, the output voltage value
directly represents position data. (Output voltage represents the distance from the center of PSD. 1 V=1 mm)
