l Position conversion formula (See Figure 3-2.)
The tetra-lateral type has four electrodes on the upper
surface, formed along each of the four edges. Photocur-
rent is divided into 4 parts through the same resistive
layer and extracted as position signals from the four
electrodes. Compared to the duo-lateral type, interaction
between the electrodes tends to occur near the corners
of the active area, making position distortion larger. But
the tetra-lateral type features an easy-to-apply reverse
bias voltage, small dark current and high-speed re-
sponse. The light input position for the tetra-lateral type
shown in Figure 3-4 is given by conversion formulas (3-
3) and (3-4), which are the same as for the duo-lateral
type.

This is a variant of the tetra-lateral type PSD with an im-
proved active area and reduced interaction between elec-
trodes. In addition to the advantages of small dark current,
high-speed response and easy application of reverse bias
that the tetra-lateral type offers, the circumference distor-
tion has been greatly reduced. The light input position of
the pin-cushion type shown in Figure 3-6 is calculated from
conversion formulas (3-5) and (3-6), which are different
from those for the duo-lateral and tetra-lateral types.
