Abstract
The present invention integrates a structured light source into an imaging system for reconstructing surface topography of an object being imaged. The structured light source includes a mechanism for transmitting a set of lines onto the object from an angle. The lines are displaced, or phase shifted relative to a stage, when they encounter an object with finite height, such as a mouse. This phase shift provides structured light information for the object. A camera captures the structured light information. Using software that employs a structured light analysis, surface topography data for the object is determined from the phase shift of the lines.
