Abstract: Multispectral imaging of samples, in particular of biological tissues. A method for acquisition of fluorescence and reflectance images of an object including alternatingly illuminating the object with at least a first light having several spectral regions of high intensity, wherein the first light has at least one region of low intensity that is of longer wavelength to a region of high intensity, and at least a second light having at least one spectral region of high intensity, recording a first image of the object during illumination of the object with the first light and a second image of the object during illumination of the object with the second light using a common sensor array, wherein the light recorded by the sensor array is attenuated in at least one of the spectral regions in which the first light has high intensities.

Abstract: Multispectral imaging of samples, in particular of biological tissues. A method for acquisition of fluorescence images and reflection images of an object including alternatingly illuminating the object with at least a first light and a second light, wherein the first light and the second light are spectrally shaped such that at least one light has several spectral regions of high light intensity separated by spectral region(s) of low light intensity, wherein the spectral regions of the first light and the second light with high intensity at least partially do not overlap and wherein at least one of the two lights has at least one region of low light intensity that is of longer wavelength to the neighboring region of high light intensity, and recording at least a first image of the object and a second image of the object while illuminating the object with at least one of the lights.
