Theoretical investigation on measurement range of a femtosecond laser chromatic confocal probe by utilizing side-lobe of axial response

2018 IEEE International Conference on Advanced Manufacturing (ICAM), 2018
In this paper, by moving and adjusting the collecting lens suitably, the main-lobe is moved to the position where gap between main-lobe and side-lobe is located, aimed at solving the problem of discontinuous measurement range. So that the side-lobe of the axial response can be utilized for the purpose of extending the measurement range of the ...

Measurement of Axial Position of a Microsphere Using Chromatic Confocal System for Probe System Based on the Laser Trapping with the Standing Wave Scale

2014 International Symposium on Optomechatronic Technologies, 2014
We have proposed surface scanning measurement based on the laser trapping based probe with the standing wave scale (SWS). A scale resolution of SWS is subject to the wavelength of laser and of the hundred nm order, so the interpolation of the SWS is required.
