Signal processing circuit for 1-D PSD
Circuit board for easier 1-D PSD operation

FEATUREs
● No complicated adjustments required
   Position can be measured just by installing a 1-D PSD on
   the board.
● Accurate position sensing
   Position data of light spot is independent of light intensity.
● Compact design
   Head amp, signal addition/subtraction circuits, and analog
   divider circuit are mounted on a compact PC board.

APPLICATIONs
● Displacement measurements using DC light
● Various studies using 1-D PSD
● Performance evaluation of 1-D PSD
