PSD
Signal processing circuit for 2-D PSD
C4674, C4757, C4758, C7563
Signal processing circuit designed to facilitate operation of 2-D Position Sensitive Detector
Features
Position measurement can be made simply by mounting
2-D PSD.
l
Output voltage directly representing the position data
The position (mm) of a light spot from the PSD center is
obtained as an output voltage (V).
l
Accurate position detection
Accurate position data can be obtained, independent of
light intensity.
l
Compact on-board configuration
A head amplifiers, signal addition/subtraction circuits, and
analog divider are mounted on a compact PC board.
Applications
l
No complicated adjustment required
l
Displacement measurements using 2-D PSD
l
Various studies using 2-D PSD
l
Evaluation of 2-D PSD

q
DC signal processing circuit
Suitable for DC light displacement measurement.
q
AC signal processing circuit
Designed specifically for pulse (AC) signal detection.
Has a synchronous circuit, S/H (sample & hold) circuit and LED driver circuit.
Use of a pulse-driven LED ensures reliable operation even under background light.
