OPTICAL PROFILER AND METHODS OF USE THEREOF

摘要

An optical profiler includes a light source configured to provide a light spot on a surface of an object of interest. A light receiver including a lens and a photosensor is configured to receive and image light from the surface of the object. A profile measurement computing device is coupled to the photosensor and includes a processor and a memory coupled to the processor which is configured to be capable of executing programmed instructions comprising and stored in the memory to calculate a plurality of location values for the light spot on the surface of the object based on the imaged light from the surface of the object, wherein each of the location values are associated with an angular rotation value based on a rotation of the object about a rotational axis. A profile of the object is generated based on the calculated location values.
