This enables extraction of a measurement that represents the height of the sample, without recourse to averaging or filtering, that may be used to form an image of the sample. The detection system may also include a feedback mechanism that is operable to maintain the average value of a feedback parameter at a set level.Type: GrantFiled: December 11, 2009Date of Patent: July 2, 2013Assignee: Infinitesima Ltd.Inventor: Andrew Humphris
