s Conversion formula of spot light position on the PSD
If output signals (photocurrent) I1 and I2 are obtained
from electrodes X1 and X2, then the light spot position
(x) on the PSD can be found by the following formula.
I2 - I1

s Example of position detectability (Ta=25 °C,
λ=900 nm, spot light size: φ0.2 mm)
s Correction for position detection error
Position detection characteristics obtained by the above
formula can be corrected to reduce position detection
errors. For example, the maximum position detection
error (±120
m) of S3931 can be significantly reduced
to ±9
m by using the least square method.
