Abstract: A lens array microscope includes a lens array, an illuminating unit for illuminating a sample, and an image sensing unit. The lens array includes a plurality of lenses. The sample is positioned between the illumination unit and the lens array. An image sensing unit is positioned at an image plane of the lens array, and the sample is positioned at a corresponding focal plane of the lens array. The lens array has an unfragmented field of view including a part of the focal plane.

Abstract: An apparatus for acquiring intensity and depth information images may comprise: an image sensing unit having first radiation-sensitive elements and groups of second radiation-sensitive elements in a flat or curved plane having at least two directions, the first radiation-sensitive elements and groups of second radiation-sensitive elements to receive, respectively, an intensity image and a depth information image, at least two groups of second elements extending in each of the two directions of the plane; first micro-lenses, each of which is arranged to convey radiation to a corresponding one of the first elements; and second micro-lenses, each of which is arranged to convey radiation to a corresponding group of the second elements.

Abstract: Systems for calculating regression coefficients for estimating amounts of components in a mixture of components may comprise: a unit for supplying input optical measurements of a reference mixture, a unit for supplying learning optical measurements of the mixture, a unit for calculating component amounts from the learning measurements, a unit for obtaining the input measurements and the component amounts and calculating learned regression coefficients over the input measurements and the component amounts, and a unit for storing the coefficients, wherein the learning measurements are characterized by one or more of (1) having more bands than those of the input measurements and (2) being narrowband measurements.
