1. A method for characterising one or more objects in a sample, the method comprising:
collecting transmitted, refracted, scattered, diffracted, or emitted light from the sample, for forming collected light;
guiding the collected light using one or more lenses to a sensor surface, wherein the collected light from the sample along the one or more lenses to the sensor surface defines an optical path;
forming by said collected light on the sensor surface a first image and a second image of the one or more objects, wherein for the first image or for the second image the collected light is modulated asymmetrically by moving a light modulator between a first position for the first image and a second position for the second image; and
determining a position along the optical path of at least one of the one or more objects based on a translation of a depiction of the at least one object between the first image and the second image.
