Abstract
Official abstract text for this publication.
Methods for performing a scheme that results in a refined measurement pattern within an optical grid are provided. Physically adjusting spacing of elements within an optical grid to achieve enhanced resolution is historically unfeasible, as reduction of the spacing causes light sensors of the optical grid to pick up false signals when reading light beams. Technology introduced by the present invention generates a virtual reduced spacing of the elements within the optical grid by using two signals that are slightly different. These slightly different signals can accomplish, at least, quarter-grid spacing resolution within the optical grid. Additionally, the enhanced resolution derived from the virtual reduced spacing is employed to govern movement of a motor. The motor movement is in response to one or more changes of direction such that the motor is operating in its linear range. Advantageously, the virtual reduced spacing allows for substantial movement in a non-linear phase, while only limited movement in a linear phase is necessary to locate accurately a target within the optical grid.
First claim
Opening claim text (preview).
The invention claimed is: 1. One or more non-transitory computer-readable storage media having computer-useable instructions embodied thereon for performing a method of virtually reducing spacing of components within an optical grid by detecting wavelengths of light emitted from at least a single light source impinging upon the optical grid, the method comprising: receiving input from a first beam of light by reading the first beam of light using a first sensor and a second sensor…
