Optical imaging method, and an apparatus for optical imaging

摘要

In an imaging method, an object to be examined is treated with an optically activatable contrast medium and illuminated via a plurality of LEDs. Luminescent light excited by the irradiation is detected by a detector. The LEDs have emission wavelengths preferably different from one another. There are preferably different spectral filter combinations present that respectively include as a structural unit, an excitation filter for selecting an excitation wavelength from the radiation output by the excitation source, and a luminescence filter for filtering out wavelengths above the expected emission maximum of the luminescent light.
