摘要

设计、制造并测试了基于林尼克干涉仪的宽场显微镜。采用移相法和偏振单光法测量干涉图案。这两种方法都使用低相干性发光二极管作为光源，Z 方向的分辨率达到 10 纳米，X 和 Y 方向的分辨率达到衍射极限。单次拍摄法对振动不敏感，因此可以观测移动物体。该仪器操作简单、成本低廉，因此具有广泛的应用价值。

Optical microscope with nanometer longitudinal resolution based on a Linnik interferometer

A widefield microscope based on a Linnik interferometer was designed, constructed, and tested. The phase-shifting and polarized single-shot methods were used to measure interference patterns. Both methods use a low-coherence light-emitting diode as the light source, achieving a resolution of 10 nm in the Z direction and diffraction-limited resolution in the X and Y directions. The single-shot method is vibration-insensitive, allowing for the observation of moving objects. The simplicity and low cost of this instrument make it valuable for a wide range of applications.

期刊介绍： Journal of Optics publishes new experimental and theoretical research across all areas of pure and applied optics, both modern and classical. Research areas are categorised as: Nanophotonics and plasmonics Metamaterials and structured photonic materials Quantum photonics Biophotonics Light-matter interactions Nonlinear and ultrafast optics Propagation, diffraction and scattering Optical communication Integrated optics Photovoltaics and energy harvesting We discourage incremental advances, purely numerical simulations without any validation, or research without a strong optics advance, e.g. computer algorithms applied to optical and imaging processes, equipment designs or material fabrication.
