    Abstract: According to embodiments, an image bitmap is modified to compensate for non-idealities in actual beam locations delivered by a scanned beam or laser scanner system compared to desired pixel locations. For a non-ideal actual beam location, pixel values for neighboring desired pixel locations may be used to generate a compensated actual pixel value. According to some embodiments, the compensated actual pixel value may be a weighted average of the neighboring desired pixel values. The weighting factors may be determined from the actual beam location compared to the desired respective pixel locations. The system may compensate for various distortions including optical aberrations and scanning distortion.

    Abstract: A MEM s scanning device has a variable resonant frequency. In one embodiment, the MEMs device includes a torsion arm that supports an oscillatory body. In one embodiment, an array of removable masses are placed on an exposed portion of the oscillatory body and selectively removed to establish the resonant frequency. The material can be removed by laser ablation, etching, or other processing approaches. In another approach, a migratory material is placed on the torsion arm and selectively stimulated to migrate into the torsion arm, thereby changing the mechanical properties of the torsion arm. The changed mechanical properties in turn changes the resonant frequency of the torsion arm. In another approach, symmetrically distributed masses are removed or added in response to a measured resonant frequency to tune the resonant frequency to a desired resonant frequency. A display apparatus includes the scanning device and the scanning device scans about two or more axes, typically in a raster pattern. Various approaches to controlling the frequency responses of the scanning device are described, including active control of MEMs scanners and passive frequency tuning.
