Patent ID: 7041951

Claim:
A method for investigating at least one tissue layer using a microscope, the method comprising the following steps: focusing the microscope onto the tissue layer being investigated, wherein the tissue layer is in a living animal; sensing positional changes of the tissue layer caused by movements of the animal or by movements of the animal's organ, or sensing at least a beginning of the positional changes; generating signals with an electronic system that correspond to the positional changes of the tissue layer; acquiring images or/and performing optical measurements corresponding to the positional changes even during the positional changes of the tissue layer, and storing the signals together with the images or/and the results of the optical measurements for later evaluation, in which later evaluation the images or the results of optical measurements made when the tissue layer being investigated is in focus are identified on the basis of the signals, or processing the signals in such a way that the positional changes are compensated for in real time and the tissue layer being investigated is thereby in focus.
