Abstract
Modern optical systems rely on scanning platform not only to broaden the field of view but also to enhance the viewing resolution. This thesis discusses a computer aided engineering (CAE) approach to a novel high speed optical scanning platform [1]. By aid of the accurate system identification and the dynamic simulation and analysis, the scanning platform achieved by the design is able to comply with some very high performance motion requirements. The optical scanning platform [1] uses piezoelectric transducers (PZT) with flexure joints. The scanning range of the novel optical scanning platform [1] can reach as wide as 3.84 mrads and minus 3.84 mrads after feedback. Different scanning reference demands are scheduled with an ILC controller in an attempt to achieve enhanced resolutions. The scanning resolutions are 10 μrad and 6.67 μrad in each scanning direction when operated respectively under the ILC controller. Experimental results are also provided to show the efficacy of the proposed approach.
