Abstract:
A light intensity modulation method implemented by using a mask ( 101 ) includes the steps of: 1) based on a circle of confusion (CoC) function of an illumination system ( 102 ), an initial light intensity distribution of an illumination field of view (FOV) and a target light intensity distribution of the illumination FOV, calculating a transmittance distribution of the mask ( 101 ) used to modulate the initial light intensity distribution into the target light intensity distribution; 2) meshing the mask ( 101 ) according to a desired accuracy of the target light intensity distribution and determining a distribution of opaque dots in each of cells resulting from the meshing based on the transmittance distribution of the mask ( 101 ) and a desired accuracy of the transmittance distribution; and 3) fabricating the mask ( 101 ) based on the determined distribution of the opaque dots and then deploying the mask ( 101 ) in the illumination system. Advantages including a high modulation accuracy, an applicability to wide FOV size, light intensity and wavelength ranges and compatibility with established manufacturing processes can be attained.

Claim (Index 4):
The light intensity modulation method according to  claim 1 , wherein determining the distribution of the opaque dots in each of the cells based on the transmittance distribution of the mask and the desired accuracy of the transmittance distribution in step 2) comprises: calculating an area of opaque dots based on a criterion that a ratio of the area of opaque dots to an area of a corresponding one of the cells is not greater than the desired accuracy of the target light intensity distribution; and determining, by fitting, a number of the opaque dots and a pitch of the opaque dots in a corresponding one of the cells based on the transmittance distribution of the mask and on the area of the opaque dots.
