Abstract
A process for obtaining an object image of at least one object (40) is described, wherein at least two partial images of the object (40) are taken under differing object conditions which are formed on the object with spatial patterns, wherein a non-linear dependence of the light detectable from the object point on the object conditions given at the object point exists and the partial images contain different contributions of various space frequency components of the object structure, and the desired object image is determined from the partial images by reconstruction of the space frequency components. Optical systems for implementing this type of process are also described.
Claims23
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.
An topical imaging system comprising:
- an illumination device and a detector device arranged for illuminating an object and recording an image of the object or of parts of the object,
- at least one pattern generator arranged for generating 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 at least one pattern generator being arranged for forming said object conditions on the object with at least one spatial pattern, with the illumination device and/or the pattern generator being arranged for generating said object conditions such that 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, and
- an image generator arranged for computational reconstruction of an object image from partial images which were recorded with the detector device.
