Bridging quantum mechanics and nonlinear optics in Raman scattering

Naoki Fukutake, Hideaki Kano

We present a theoretical framework for spontaneous Raman scattering that fundamentally bridges quantum-mechanical and nonlinear-optical approaches. By conceptualizing spontaneous R…

Theoretical analysis of performance limitation of computational refocusing in optical coherence tomography

Yue Zhu, Shuichi Makita, Naoki Fukutake +1

High-numerical-aperture optical coherence tomography (OCT) enables sub-cellular imaging but faces a trade-off between lateral resolution and depth of focus. Computational refocusin…

Image formation theory of optical coherence tomography with optical aberrations and its application for computational aberration correction

Shuichi Makita, Naoki Fukutake, Lida Zhu +1

Computational corrections of defocus and aberrations in optical coherence tomography (OCT) offers a promising approach to realize high-resolution imaging with deep imaging depth, b…

Unified image formation theory for microscopy and optical coherence tomography in 4-D space-time

Naoki Fukutake, Shuichi Makita, Yoshiaki Yasuno

We construct an image formation theory that covers the majority of optical microscopy techniques that use diverse coherent or incoherent light-matter interactions. The theories of…

Four-dimensional image formation theory of optical coherence tomography

Naoki Fukutake, Shuichi Makita, Yoshiaki Yasuno

We construct an accurate imaging theory for optical coherence tomography/microscopy (OCT/OCM) without approximations to calculate precise optical resolution and imaging characteris…
