Patent ID: 8711186

Claim:
An apparatus comprising: a laser light source; a mirror being oscillatable on a first axis, the mirror being positioned to reflect light from the laser light source and sweep a light beam sinusoidally through an angle and across a display surface in a first dimension, resulting in tangential distortion in the light beam location on the display surface as a function of time; and a beam position determination component that determines a location of the light beam on the display surface, wherein the beam position determination component determines the beam location as a function of the sinusoidal sweep as well as the tangential distortion, and wherein the beam position determination component determines the pixel location as: x = HRES 2 ⁢ tan ⁡ ( A ⁢ ⁢ sin ⁡ ( ω ⁢ ⁢ t ) ) tan ⁡ ( A ) + HRES 2 .
