Abstract:
This invention addresses a contact mode hybrid scanning system (HSS), which can be used for measuring topography. The system consists of a cantilever or a cantilever array, a scanning stage, a light source, and instrumentation to synchronize and control the individual components. Detection of the cantilever's movement is achieved by directly measuring the change in disposition of the cantilever including its height, rotation at one or more points on the cantilever thereby providing a partial three-dimensional reconstruction without the need for actuating the cantilever. This is achieved by employing a displacement meter such as a triangulation meter or a confocal meter.
