Optical tomography with structured illumination.
We consider the image reconstruction problem for optical tomography with structured illumination. A fast image reconstruction algorithm is proposed that reduces the required number of measurements of the optical field compared to methods that utilize point-source illumination. The results are illustrated with numerical simulations.
متن کاملUltrasonic Refractive Index Tomography
Ultrasonic computed tomography (UCT) is one of the methods capable of tissue characterization. It is expected to provide not only a quantitative image but also diagnostic information. As in X-ray CT, UCT requires a projection data to reconstruct a cross-sectional image. In UCT such projection data are derived from the received broadband ultrasonic signal. In this paper, two methods for deriving...
متن کاملStructured illumination microscopy for dual-modality 3D sub-diffraction resolution fluorescence and refractive-index reconstruction.
Though structured illumination (SI) microscopy is a popular imaging technique conventionally associated with fluorescent super-resolution, recent works have suggested its applicability towards sub-diffraction resolution coherent imaging with quantitative endogenous biological contrast. Here, we demonstrate that SI can efficiently integrate together the principles of fluorescent super-resolution...
متن کاملFluorescence endomicroscopy with structured illumination.
We present an endomicroscope apparatus that utilizes structured illumination to produce high resolution (approximately 2.6 microm) optically sectioned fluorescence images over a field of view of about 240 microm. The endomicroscope is based on the use of a flexible imaging fiber bundle with a miniaturized objective. We also present a strategy to largely suppress structured illumination artifact...
متن کاملCell refractive index tomography by digital holographic microscopy.
For what we believe to be the first time, digital holographic microscopy is applied to perform optical diffraction tomography of a pollen grain. Transmission phase images with nanometric axial accuracy are numerically reconstructed from holograms acquired for different orientations of the rotating sample; then the three-dimensional refractive index spatial distribution is computed by inverse ra...
