Claims

[Scope of utility model registration request]

a fan-shaped three-quadrant detector that receives reflected light from a target and converts it into an electrical signal; a current/voltage conversion amplifier that converts and amplifies the output current of the fan-shaped three-quadrant detector; and a current/voltage conversion amplifier that converts and amplifies the output current of the fan-shaped three-quadrant detector; A signal processing device comprising: an amplifier that amplifies the output of a conversion amplifier; and a three-input arithmetic circuit that calculates a guidance error signal with respect to a target from the output of the amplifier.
