<p><P>PROBLEM TO BE SOLVED: To minimize the volume of a system while producing high contrast frames of image data. <P>SOLUTION: A system and method for performing optical navigation uses scattered light to produce frames of image data to estimate displacement with respect to a target surface. The scattered light is produced from an illumination beam of light (OI) emitted along a first optical axis onto the target surface. The illumination beam of light (OI) also produces a specularly reflected beam of light (OR) along a second optical axis. The scattered light (OC) about a third optical axis, which is offset by a predefined angleθwith respect to the second optical axis, is received at an image sensor array 218 to produce some frames of an image. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
