    Abstract: Example embodiments relate to imaging devices for in-line holographic imaging of objects. One embodiment includes an imaging device for in-line holographic imaging of an object. The imaging device includes a set of light sources configured to output light in confined illumination cones. The imaging device also includes an image sensor that includes a set of light-detecting elements. The set of light sources are configured to output light such that the confined illumination cones are arranged side-by-side and illuminate a specific part of the object. The image sensor is arranged such that the light-detecting elements detect a plurality of interference patterns. Each interference pattern is formed by diffracted light from the object originating from a single light source and undiffracted light from the same single light source. At least a subset of the set of light-detecting elements is arranged to detect light relating to not more than one interference pattern.

    Abstract: 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.

    Abstract: Example embodiments relate to methods and imaging systems for holographic imaging. One embodiment includes a method for holographic imaging of an object. The method includes driving a laser using a current which is below a threshold current of the laser. The method also includes illuminating the object using illumination light output by the laser. Further, the method includes detecting an interference pattern formed by object light, having interacted with the object, and reference light of the illumination light.

    Abstract: An apparatus for in-line holographic imaging is disclosed. In one aspect, the apparatus includes at least a first light source and a second light source arranged for illuminating an object arranged in the apparatus with a light beam. The apparatus also includes an image sensor arranged to detect at least a first and a second interference pattern, wherein the first interference pattern is formed when the object is illuminated by the first light source and the second interference pattern is formed when the object is illuminated by the second light source. The first and second interference patterns are formed by diffracted light, being scattered by the object, and undiffracted light of the light beam. The at least first and second light sources are arranged at different angles in relation to the object, and possibly illuminate the object using different wavelengths.

    Abstract: According to a first aspect, there is provided a method of holographic wavefront sensing, the method including: receiving a light beam, which has a wavefront to be analyzed, on a transparent, flat substrate, which is provided with a lattice of opaque dots, wherein the substrate is arranged above an image sensor; detecting by the image sensor an interference pattern formed by diffracted light, being scattered by the opaque dots, and undiffracted light of the light beam received by the image sensor; processing the detected interference pattern to digitally reconstruct a representation of a displaced lattice of opaque dots, which would form the interference pattern on the image sensor upon receiving the light with a known wavefront; and comparing the representation of the displaced lattice to a known representation of the lattice of opaque dots on the substrate to determine a representation of the wavefront form of the received light beam.
