Grating Nanomeasurement and Implementation Technology Based on TMS320F28335
A grating nanomeasurement device based on TMS320F28335 was presented, a novel subdivision algorithm for nanomeasurement was put forward and implemented in TMS320F28335. The analysis and test show that, through the pre-amplifying circuit well designed and through the data process algorithm optimized, the device applied with 20m pitch grating can realize 2nm resolution and greater than 200mm/s measurement speed. The experimental results of nanopositioning also demonstrate that the grating nanomeasurement device developed by the paper can be taken as nanomeasurement equipment used in nano-CMM and nanopositioning system.
