Abstract: A multimodal imaging system comprises a light source, an image sensor comprising a plurality of pixels, and an optical filter comprising a first filter element and a second filter element. The light source emits partially coherent polarized light, and the first filter element and second filter element are arranged as an array parallel to the image sensor. The first filter element is configured for attenuated transmission of a first light spectrum, which comprises polarized light emitted by the light source, and the second filter element is configured for transmission of a second light spectrum. The image sensor is configured to simultaneously capture light impinging on the image sensor from both the first filter element and the second filter element. Each filter element of the optical filter is configured for transmission of light to a subset of the imager pixels.

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: An illumination system and method for illumination of a sample in a container is described herein. In some embodiments, the container includes a defined volume for receiving the sample. The illumination system includes, in some embodiments, at least one light source, a mask comprising an opaque portion, preventing light from passing through the mask, and an at least partially transparent portion, allowing light to pass through the mask. The illumination system can be adapted to be positioned such that the light generated by the light source, passing through the mask, illuminates the sample in the container. The light source and the mask are configured such that a shape, a size, and a position of a projection of the light passing through the mask, onto a plane of a bottom surface of the container, match a shape, a size, and a position of the bottom surface.
