Quantitative Fresnel Lorentz microscopy and the transport of intensity equation

Ultramicroscopy, 2006
Imaging of the magnetic structure of thin films by the Fresnel mode of Lorentz microscopy has been re-evaluated in terms of the Ampérian current density within a sample. The conditions for which this imaging can be treated as linear are discussed for quantitative application.

Robust Transport-of-Intensity Equation with Neural Differential Equations

Optica Imaging Congress (3D, COSI, DH, FLatOptics, IS, pcAOP), 2023
We solve the transport-of-intensity equation by estimating the intensity derivative using the method of neural differential equations. We observe strong robustness to artifacts from ill-conditionedness and measurement noise.

Measurement of acylindrical surface with transport of intensity equation

Applied Optics, 2022
High-precision aspherical cylindrical (acylindrical) lenses are difficult to directly measure because of the phase deviation in the off-axis region. To achieve rapid and non-contact measurement of the acylindrical lens surface, a novel optical structure phase measurement, to the best of our knowledge, is presented in this work.

The optical refractometry using transport-of-intensity equation

Laser Physics Letters, 2022
Abstract A development of a method for measuring the refractive index of optical media based on the transport-of-intensity equation (TIE) is proposed. The method requires only a complementary metal-oxide semiconductor (CMOS) camera, which registers intensity distributions in several planes.
