Abstract:
1. A process for obtaining an object image of at least one object comprising: illuminating the object with illumination light from an illumination light source, providing at least two different object conditions on the object, said object conditions comprising light intensity of said illumination light or a physical or chemical condition at a location of the object influencing at least one characteristic of light from the object and said object conditions being formed on the object with at least one spatial pattern, wherein said light from an object point of the object having a non-linear dependency upon at least one of the object conditions or a multi-linear dependency upon at least two of the object conditions provided at the object point, capturing at least two partial images of the object corresponding to the formation of said object conditions, wherein the partial images contain different contributions of various spatial frequency components of the object structure, and determining a desired object image by computational reconstruction of the spatial frequency components.
