Abstract
A voltage control system has a light receiving array part receiving incident light and a light shielding array part shielding light receiving elements from incident light by a light shielding mechanism. The voltage control system also includes: a voltage application unit applying a bias voltage to an anode terminal; a multiplication state determination unit determining the multiplication state of the light shielding array part based on output signals from cathodes of the light receiving elements in the light shielding array part; and a voltage setting unit performing voltage setting for the bias voltage to be output from the voltage application unit based on the determination results from the multiplication state determination unit.
