Abstract
Laser differential confocal microscope owns the characteristics of high spatial resolution. But it must take more time scanning because of the characteristic of scanning imaging point by point, which easy to generate system drift by the effect of the three-dimensional scanning system and environment. A new axial lifting mechanism to construct a highly stable electric three-dimensional scanning system is designedby using the characteristics that wedge mechanism can be operation highly stable and brake mechanism can is broken free.A stability experiment is conductedon the laser differential confocal microscope built by the group.After a half hour the axial position's real-time changes of the scanning system is observed, the drift is less than 50nm by using the new three-dimensional scanning system, drift velocity is slower than using the old one which drifts 140nm.It own highly stable characteristic than the old, which significantly improves the differential confocal microscopy imaging.
