3 Difference output A is defined as follows :
A=Isc (PD1)~ Isc (PD2) Difference output increment rate (A/deg,) is the increment rate of current A at 1 deg. _ Age (PD1)—Tec (PD2)} at (+1 deg.) + {Ise (PD2)—Isc (PD1)} at (= 1 deg.) A/deg.= 2 4 The reflective object of which junction characteristics are given is a multi-layer coating mirror. %5 Sum output B is defined as follows : B=Isc (PDI) +Isc (PD2) %*6 Tilt angle output C is defined as follows : C=A/B Angle range of tilt angle output 0 is defined as the range of angles that makes C=0. #7 Monotonous increase range of tilt angle output is the range of angles with respect to which C increases monotonously with the coordinate original point at the angle that makes C=0. %*8 Non-invert rarige of tilt angle output is the range of angles that don't make C negative.
