论文摘要
双弯曲显微镜（DCM），这是一种基于光频（OFC）模式和图像像素一对一的对应关系的有趣成像模态，从扫描无扫描的全场成像和同时的共核幅度和相位成像中受益。但是，由于复杂性和成本，这两个频率稳定的OFC来源要求将DCM的实用性加剧。在这里，双向单腔双重弹纤维激光器（SCDCFL）被用作DCM低复杂性OFC源。计算图像校正减少了由SCDCFL残留正时抖动引起的图像模糊。 14.0 nm不确定性的纳米级阶跃表面验证仪突出了图像校正的DCM效率。提出的方法增强了DCM的VEST和实用性。
Dual-comb microscopy (DCM), an interesting imaging modality based on the optical-frequency-comb (OFC) mode and image pixel one-to-one correspondence, benefits from scan-less full-field imaging and simultaneous confocal amplitude and phase imaging. However, the two fully frequency-stabilized OFC sources requirement hampers DCM practicality due to the complexity and costs. Here, a bidirectional single-cavity dual-comb fiber laser (SCDCFL) is adopted as a DCM low-complexity OFC source. Computational image correction reduces the image blur caused by the SCDCFL residual timing jitter. Nanometer-order step surface profilometry with a 14.0 nm uncertainty highlights the image-corrected DCM effectiveness. The proposed method enhances the DCM versality and practicality.
