We propose an aspherical surface representation based on extended Jacobi polynomials to mitigate high-order oscillations and limited edge-fitting capability encountered in conventional polynomial descriptions of large-aperture annular optic...
OCT sidelobe suppression method based on dual-path phase sinusoidal modulation and minimum value fusion [0.03%]
基于双通道相位正弦调制极值融合的OCT边模抑制方法
Teng Liu,Zhongliang Li,Nan Nan et al.
Teng Liu et al.
In optical coherence tomography (OCT) images, sidelobe artifacts are weaker signals that emanate from regions adjacent to high-intensity sample signals. These artifacts do not correspond to actual tissue structures and can be easily misinte...
Optical design concepts using wavelength-selective diffractive optics to enable miniaturized multimodal endoscopic imaging across separated spectral ranges [0.03%]
