A application of optical and mechanical two-dimension scanning technology in the laser confocal biochip scanner

The optical and mechanical two-dimension scanning technology applied in the laser confocal biochip scanner is described firstly in this paper, one dimensional scanning is completed by the optical scanning system composed of galvanometer and f-θ objective lens, another is done by the mechanical scanning system moving the work stage by the stepping motor. And on the base of the above discussion, the design of the control system of the two dimensional scanning is analyzed. The new and helpful experiments about the laser confocal biochip scanner which has high scanning speed and precision have been done, and some preliminary experimental results are achieved.
