Abstract
A reconfiguring image brightness (RIB) module includes a switch, a first lens, a digital micro-mirror device (DMD), a second lens and a third lens. The switch selectively allows a first image having a light intensity distribution to pass, wherein the first image is formed after an illumination beam passes through a photomask. The first lens outputs a second image by modulating the size of the first image passes through the first lens, and the second image is imaged on the DMD. A third image having a reconfigured light intensity distribution is formed by the DMD, and the third image is outputted to the second lens by the DMD. A fourth image is formed after the third image passes through the second lens, a fifth image is formed after the fourth image passes through the third lens and the fifth image is outputted from the RIB module.
