| description | A sensor system for measuring a shape of a substrate, the sensor system include: a substrate support to support a surface of the substrate; at least one sensor device, each sensor device including an optical emitter to emit radiation onto the surface of the substrate, and an optical receiver to receive the radiation reflected from the surface; and a controller. The controller is configured to: determine at least one measurement height of the surface of the substrate above each of the at least one sensor device, based on the received radiation; compensate for gravitational sag of the substrate relative to a calibration height; and determine the shape of the substrate based on a comparison of the calibration height and the at least one measurement height. |
