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
   Use of pulse-driven LED allows accurate position sensing
   even under background light, and independent of pulsed
   light intensity.
● Compact design
   An LED drive circuit, head amp, signal addition/subtraction
   circuits, sample hold circuit, synchronization circuit and
   analog divider circuit are mounted on a compact PC board.

Applications
● Displacement measurements using pulsed light synchronized
   with the circuit
● Various studies using 1-D PSD
● Performance evaluation of 1-D PSD
