Method and apparatus for spatial light modulation |
摘要 |
The present invention includes a method to use a phase modulating micromirror array to create an intensity only image that has high image fidelity, good stability through focus and good x-y symmetry. The method uses pixels consisting of at least one tilting mirror element and adjacent pixels tilt in different ways, but they are laid-out in a pattern that creates effective averaging between pixels with different tilt. The pattern is such that even if a single pixel creates a reflecting or scattering pattern that is asymmetric relative to the specular direction every neighborhood consists of pixels that together create symmetry. The invention allows the use of single-mirror pixels instead of multi-element pixels, thereby making manufacturing and design easier and also makes a smaller pixel size possible. Particular aspects of the present invention are described in the claims, specification and drawings.
