Claim:
1. A scanned-spot-array lithography system comprising an array of microlenses and corresponding optical modulators, a projection system, and a scanning mechanism, wherein: the array of microlenses and corresponding optical modulators, the projection system, and the scanning mechanism operate cooperatively to print a lithographic image on a photosensitive layer when the layer is positioned proximate an image plane; each microlens receives radiation from a radiation source and focuses it into a convergent beam converging toward a corresponding intermediate focus; each convergent beam transmits through and diverges from the corresponding intermediate focus, transmits through the projection system, and is focused by the projection system onto a corresponding focused-radiation spot on the image plane; the optical modulator corresponding to each microlens is positioned to intercept the corresponding convergent beam proximate the intermediate focus, and operates to modulate the radiation transmitting to the corresponding focused-radiation spot; and the scanning mechanism raster-scans the photosensitive layer relative to the focused-radiation spots in synchronization with the modulation to record a synthesized, high-resolution raster image on the photosensitive layer.
