3D particle tracking using transport of intensity equation (TIE)
Optics Express, 2022 This article presents a simple and high-speed approach for tracking colloidal spheres in three dimensions. The method uses the curvature of the wavefront as determined by the transport of intensity equation (TIE) technique. Due to the fact that the TIE is applicable under partially coherent light, our technique is fully compatible with standard bright ...

Transport of intensity equation: a tutorial
Optics and Lasers in Engineering, 2020 Abstract When it comes to “phase measurement” or “quantitative phase imaging”, many people will automatically connect them with “laser” and “interferometry”. Indeed, conventional quantitative phase imaging and phase measurement techniques generally rely on the superposition of two beams with a high degree of coherence: complex interferometric ...

Multimodal computational microscopy based on transport of intensity equation [PDF]
Journal of Biomedical Optics, 2016 Transport of intensity equation (TIE) is a powerful tool for phase retrieval and quantitative phase imaging, which requires intensity measurements only at axially closely spaced planes without a separate reference beam. It does not require coherent illumination and works well on conventional bright-field microscopes.

Stability of Intracellular Protein Concentration under Extreme Osmotic Challenge
Cells, 2021 Cell volume (CV) regulation is typically studied in short-term experiments to avoid complications resulting from cell growth and division. By combining quantitative phase imaging (by transport-of-intensity equation) with CV measurements (by the exclusion

Variational Phase Imaging Using the Transport-of-Intensity Equation [PDF]
IEEE Transactions on Image Processing, 2016 We introduce a variational phase retrieval algorithm for the imaging of transparent objects. Our formalism is based on the transport-of-intensity equation (TIE), which relates the phase of an optical field to the variation of its intensity along the direction of propagation.

Transport of intensity equation method and its applications [PDF]
Microscopy, 2020 Abstract A phase retrieval technique based on a transport of intensity equation (TIE) is one of the defocus series reconstruction techniques in microscopy. Since it does not require any dedicated devices like a biprism, and only three defocus images are enough to retrieve phase information, it has been applied to observe magnetic fields,

Real-Time Phase Retrieval Based on Cube-Corner Prisms Single Exposure
Photonics, 2022 The phase retrieval method based on the Transport of Intensity Equation needs to record the light intensity information on two or more planes perpendicular to the optical axis propagating along the optical axis. Usually, a single CCD camera is moved back
