Paper Abstract

Differential confocal theta microscope (DCTM) which has high axial resolution, provides a feasible tool for precise measurement. The virtual pinhole detection technology can significantly simplify the optical path alignment, and enhance imaging quality of the system by optimizing virtual pinhole parameters. Based on the imaging principle of DCTM, a new method for automatic adjusting and optimizing virtual pinhole parameters is presented according to the position and size of the imaging spot, which eliminate the influence caused by the deformation and shifting of imaging spot and ensure the axial resolution. The theoretical analyses and experimental results show that optimizing virtual pinhole parameters can guarantee the axial resolution and signal-to-noise ratio as well as effectively improve the imaging quality of DCTM.
