研究目的
To improve the performance of classical digital holographic microscopy (DHM) architectures by physically compensating phase distortions without the need for digital post-processing.
研究成果
The paper presents several solutions to overcome the limitations of conventional DHM setups by physically removing quadratic phase distortions. These include telecentric DHM, flexible physical compensation using a liquid lens, and a compact, single optical-path DHM. Experimental results validate these proposals, demonstrating improved performance in quantitative phase imaging.
研究不足
The need for precise alignment and the potential for mechanical instability in some configurations. The reliance on specific optical components like liquid lenses and Fresnel biprisms may limit general applicability.
