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.
