A method for retrieving phase information in a coherent diffraction imaging process includes acquiring a plurality of 3D data sets, each 3D data set corresponding to one of a plurality of time states, and reconstructing a 3D image of the object at a given time state using the 3D data set from all of the time states. Each 3D data set is acquired by: illuminating an object positioned in a first position with a coherent beam; measuring a first 2D diffraction pattern using an area detector; rotating the object around a tilt axis thereof to a second position that is different from the first position; re-illuminating the object positioned in the second position with the coherent beam; re-measuring a second 2D diffraction pattern using the area detector; and repeating the rotating, re-illuminating and re-measuring steps such that each 3D data set includes a predetermined number of diffraction patterns.

Disclosed is a hologram stage setting which is configured to apply a net screen of a grid network structure coated by a ceramic ball lens on the front part of a stage and directly project images, thereby enabling performance without specific limits on general multi-purpose stages instead of special stages, solving high cost problems caused by using a conventional foil screen, implementing high-resolution images, enhancing durability, and performing easy maintenance and repair. The hologram stage setting includes: a rear screen which is installed on the rear part of a stage to display a rear background image; a lower screen which is installed on the lower part of the stage to display a lower background image; a front screen which is installed on the front part of the stage to display a front hologram image; and a front hologram image projector which generates and projects the front hologram image.

Embodiments described herein relate to lens-free imaging. One example embodiment may include a lens-free imaging device for imaging a moving sample. The lens-free imaging device may include a radiation source configured to emit a set of at least two different wavelengths towards the moving sample. The lens-free imaging device is configured to image samples for which a spectral response does not substantially vary for a set of at least two different wavelengths. The lens-free imaging device may also include a line scanner configured to obtain a line scan per wavelength emitted by the radiation source and reflected by, scattered by, or transmitted through the moving sample. The line scanner is configured to regularly obtain a line scan per wavelength. Either the radiation source or the line scanner is configured to isolate data of the at least two different wavelengths.

An observation apparatus includes a light source, a beam splitter, a mirror, a mirror, a cylindrical lens, a lens, a cylindrical lens, a beam splitter, a lens, a frequency shifter, an imaging unit, and an analysis unit. The analysis unit generates a complex amplitude image of each of a plurality of light irradiation directions of object light based on time series data of an interference intensity image output from the imaging unit, and generates a three-dimensional complex differential interference image of an observation object based on the complex amplitude image of each of the plurality of light irradiation directions. The analysis unit obtains a three-dimensional phase image of the observation object based on the three-dimensional complex differential interference image.

The invention improves holographic imaging systems by being modular with deployment in a lens-less configuration or with a microscope objective, leading to a resolution range of 5.5 and to 0.5 m/pixel, respectively, and resulting in a resolvable particle size range of several microns to a few cm between two setups. The invention includes variable sampling length between two windows (e.g., a sampling volume of 71.4 mL per hologram at 12 cm). Holograms are recorded with a 49203280 pixels digital camera. i.e., 15.3 MB per image, at a maximum rate of 3.2 Hz, such that free stream water sampling a 14 L/minute occurs. This is orders of magnitude higher than sampling of other imaging systems while including larger/variable sample volume, inclusion of copper shutters to prevent biofouling during long-term deployments, including deployment in different operation modes. No single previous system achieves all these things at the same time.

A phenotypic profiling method for drug/dose physiological response of living bodies utilizes feature recognition to segment the information in time-frequency tissue-response spectrograms to construct N-dimensional feature vectors. The feature vectors are used to generate a correlation matrix among a large number of different stimuli in the form of drugs, doses and conditions. Multi-dimensional scaling is applied to the correlation matrix to form a two-dimensional map of response relationships that retains rank distances from the higher-dimensionality feature matrix. The two-dimensional phenotypic profile space displays compact regions indicative of particular physiological responses, such as regions of enhanced active transport, membrane undulations and blebbing.
