Features
l
No complicated adjustments required
Position can be measured just by installing a 1-D PSD on
the board.
l
Accurate position sensing
Position data of light spot is independent of light intensity.
l
Compact design
Head amp, signal addition/subtraction circuits, and analog
divider circuit are mounted on a compact PC board.
Applications
l
Displacement measurements using DC light
l
Various studies using 1-D PSD
l
Performance evaluation of 1-D PSD

*2: PSD does not operate correctly if the input signal current is outside the specified range.
*3: With no PSD installed, 20 μA (X1=X2) is supplied to the circuit as current signal that substitutes for PSD photocurrent
