Abstract:
Method and system for calculating a height map of a surface of an object from an image stack in scanning optical  2.5 D profiling of the surface by an optical system, a focal plane is scanned at different height positions with respect to the object surface. An image is captured at each height position of the focal plane to form the image stack. The scanning of the focal plane comprises long range sensing and short range sensing a displacement of the focal plane for sensing low and high spatial frequency components. The height position of the focal plane is estimated by combining the low and high spatial frequency components. A height position of each image in the image stack is calculated, based on the estimated height position of each respective focal plane. The images of the image stack are interpolated to equidistant height positions for obtaining a corrected image stack.

Claim (Index 7):
The method according to  claim 5 , wherein:\n the short range sensing is performed from the object, or from an object stage supporting the object, and the short range sensing is based on a difference of a displacement sensed by the short range sensing performed from the optical system and a displacement sensed by the short range sensing from the object or from the object stage supporting the object.
