Abstract
A method for characterizing object(s) in a sample includes collecting transmitted, refracted, scattered, diffracted, and/or emitted light from the sample. The collected light formed on a sensor surface includes at least a first and second image of the object(s). For at least the first and second image, the collected light is modulated asymmetrically differently, or for at least a third and fourth image focal plane positions are different, or for at least a fifth image the collected light is modulated in at least two places differently compared to the surroundings, or for at least a sixth and seventh image of the object(s), the collected light is modulated asymmetrically differently and focal planes of the sixth and seventh image have different positions. The images are processed to characterize the objects(s).
