Claim 2:
3. The method for detecting the centroid of the complementary single pixel according to claim 1, wherein
in S3, the intensity values of the reflected light acquired by calculating the first single-pixel detector and the second single-pixel detector are represented as:

l1,k0=Σx,yf(x,y)Sk0(x,y)  (3)

l2,k1=Σx,yf(x,y)Sk1(x,y)  (4)

in the formula, f(x,y) is a two-dimensional distribution function of the image of the target object, a superscript takes 0 and 1, which correspond to states of a positive angle and a negative angle of the DMD in respective, a subscript takes 1 and 2, which represent the first single-pixel detector and the second single-pixel detector in respective, k takes 1 and 2, which represent two two-dimensional modulation information of the DMD in respective, and Sk1 and Sk0 represent two complementary modulation information under a kth modulation information in respective.
