Description
Summary:High-quality optical observation through traditional microscopes faces significant challenges due to their low spatial sampling and the limited ability to respond only to the light intensity characteristics of optoelectronic devices. This limitation results in an inability to measure other critical optical information during imaging, such as phase, angle, polarization, and coherence. In response to these challenges, light field microscope (LFM) as a powerful imaging technique is capable of measuring samples with unprecedented depth and detail. LFM overcomes the limitations of conventional microscope methods by capturing both spatial and angular information of light rays. To further demonstrate these capabilities, the LFM based on microlens arrays is constructed here. These arrays are fabricated using advanced techniques such as laser lithography, microimprinting, and self-assembly technology. Using light field imaging, image segmentation methods, and deep learning fusion, the imaging quality is nearly doubled, significantly enhancing the quality of observations. LFM based on microlens arrays offers great promise for improving the quality of imaging observations in the field of microsope. [2023-0167]
