A lighting device 110 radiates first reference light S1_1 having a first intensity distribution Ir(x, y) and second reference light S1_2 having a second intensity distribution Ir^(x, y), which is in a complementary relationship with the first intensity distribution Ir(x, y). A light detector 120 measures reflected light S2_1, S2_2 from an object. A computational processing device performs a first correlation calculation utilizing a first detection intensity br and the intensity distribution of the first intensity distribution Ir(x, y), the first detection intensity br being based on the output of the light detector 120 when the first reference light S1_1 is radiated, and also performs a second correlation calculation utilizing a second detection intensity br^ and the second intensity distribution Ir^(x, y), the second detection intensity br^ being based on the output of the light detector 120 when the second reference light S1_2 is radiated.

    照明装置(110)照射第1参照光(S1_1)和第2参照光(S1_2),该第1参照光(S1_1)具有第1强度分布(Ir(x,y)),该第2参照光(S1_2)具有与第1强度分布(Ir(x,y))处于互补关系的第2强度分布(Ir^(x,y))。光检测器(120)对来自物体的反射光(S2_1、S2_2)进行测定。运算处理装置进行利用了基于照射第1参照光(S1_1)时的光检测器(120)的输出的第1检测强度(br)和第1强度分布(Ir(x,y))的强度分布的第1相关计算,并进行利用了基于照射第2参照光(S1_2)时的光检测器(120)的输出的第2检测强度(br^)和第2强度分布(Ir^(x,y))的第2相关计算。
