Apparatus and methods are described for use with a blood sample. Using a microscope (24), three images of a microscopic imaging field of the blood sample are acquired, each of the images being acquired using respective, different imaging conditions, and the first one of the three images being acquired under violet-light brightfield imaging. Using at least one computer processor (28), an artificial color microscopic image of the microscopic imaging field is generated, by mapping the first one of the three images to a red channel of the artificial color microscopic image, mapping a second one of the three images to a second color channel of the artificial color microscopic image, and mapping a third one of the three images to a third color channel of the artificial color microscopic image. Other applications are also described.

The present invention relates to a method of reading out information from a data carrier and to a data carrier utilizing the concept of structured-illumination microscopy or saturated structured-illumination microscopy.

Systems and methods for passive multi-directional illumination in light-sheet fluorescence imaging and microscopy are disclosed herein. An elliptical light shaping diffuser is placed in the illumination path between the source of a light-sheet and the illuminated sample. The light-sheet is diffused anisotropically along two directions perpendicular to its propagation direction, eliminating stripe artifacts in obtained images. The method includes converting a light-sheet into an elliptically diffuse light-sheet by passing it through an elliptical light shaping diffuser, illuminating a sample with the elliptically diffuse light-sheet. The system includes a light-sheet source, an elliptical light shaping diffuser adapted to convert the light-sheet into an elliptically diffuse light-sheet to illuminate the sample, typical microscopy optics and lenses, and image capturing elements.

A method for measuring a position of a fluorophore includes configuring a set of compact light distributions, the set having at least one member, each light distribution characterized by a center, so that there is substantially zero intensity at the center of the set of compact light distributions.
