The grating comprises a plurality of slits, the slits have a light transmitting function, and a shading area is arranged between every two adjacent slits and has a shading function. The slit width of each slit is W1, the slit distance between two adjacent slits is W2, and W1/(W1+ W2) ═ P1/2P.

obtaining:
h＝PS3/L1；
(W1+W2)＝2PL1/(L1+P)；
W1＝P1L1/(L1+P)
this makes it possible to obtain a grating aperture ratio AR of W1/(W1+ W2) of P1/2P.
