Tomographic Incoherent Phase Imaging, a Diffraction Tomography Alternative
Quantitative phase imaging (QPI) is a powerful method to visualize semi-transparent samples in a quantitative manner, in particular for thin samples. In standard setups, coherent illumination only gives access to limited object frequencies, in particular along the optical axis, avoiding accurate 3D visualization of thicker samples. In diffraction tomography, the object frequency space is filled...
متن کاملWhite Light Diffraction Phase Microscopy
Quantitative phase imaging (QPI) techniques are very advantageous compared to the qualitative phase imaging techniques like bright field microscopy, phase contrast microscopy, differential interference contrast microscopy due to measurement of phase information quantitatively. In QPI techniques, there is no need of exogenous contrast agents to stain or tag the specimen. White light diffraction ...
متن کاملFast phase reconstruction in white light diffraction phase microscopy.
In off-axis interferometry, we usually have to deal with the unwrapping process, which is very computationally intensive and prevents us from real time phase reconstruction. The wrapping problem usually occurs when imaging thick objects, which introduce phase shifts of more than 2π radians. However, in off-axis interferometry, the nonzero angle of interference of the two beams creates a ramp in...
متن کاملDiffraction phase microscopy with white light.
We present white light diffraction phase microscopy (wDPM) as a quantitative phase imaging method that combines the single shot measurement benefit associated with off-axis methods, high temporal phase stability associated with common path geometries, and high spatial phase sensitivity due to the white light illumination. We propose a spatiotemporal filtering method that pushes the limit of the...
متن کاملIncoherent "slow and fast light".
We show experimentally that the effects of pulse delay and advancement usually ascribed to the "slow and fast light" under conditions of the coherent population oscillations (CPO) can be universally observed with incoherent light fields on objects with the pure-intensity nonlinearity. As a light source, we used an incandescent lamp and as objects for study, a photochromic glass and a thermochro...
