Two-dimensional PSD

······························

Two-dimensional PSDs are classified by structure into a tetra-lateral type and a

duo-lateral type. The tetra-lateral type features high-speed response and low

dark current. The duo-lateral type offers small position detection error and high

position resolution. A pin-cushion type, which is a tetra-lateral type with

improved active area and electrodes, has a position detection error as small as

the duo-lateral type while still having the advantages of the tetra-lateral type.
