Operating Principle

A striped pattern specifically for the auto-focus application is projected onto the target sample. The reflected striped pattern and the target sample image are simultaneously transferred to the image sensing module, where through passing the beam splitter two divergent light beams are formed with differential light path lengths and are directed respectively to two separate line sensors. By comparing the photo-electronic signals between the two line sensors, the shift in focus can be accurately and speedily adjusted with high traceability.
