Abstract: In a method for the spectrally resolved measurement of optical properties of samples, a sample is arranged at a measurement position, and light is generated using a light source. Spectral components of the light are transmitted as excitation light in a first optical path to the sample. Light that has been emitted or transmitted by the sample is transmitted in a second optical path to a detector. A tunable monochromator is arranged in the first optical path and/or in the second optical path. A spectrum of the emitted or transmitted light is recorded over an effective spectral range by shifting a spectral passage range of the tunable monochromator. The method is characterized in that light in the form of light pulses with a specifiable pulse frequency is used. The spectral passage range of the tunable monochromator is shifted at a shifting speed continuously from an initial wavelength to an end wavelength for recording a spectrum.

Abstract: A device for a multimodal imaging examination of an object, in particular for a multimodal imaging examination of a living object, includes an object carrier for accommodating at least one object to be examined, an x-ray radiation source for emitting x-ray radiation, a first partial system for generating a first image of the object in a first image recording mode and a second partial system for generating a second image of the object in a second image recording mode. The first partial system has a direct digital x-ray detector which is configured to convert x-ray radiation modified by the object into a digital image of the object. The second partial system has a camera system which is configured to convert radiation in the visible wavelength range or UV wavelength range emanating from an object into a digital image of the object.

Abstract: A method for characterizing a sample by imaging fluorescence microscopy includes detecting fluorescence intensity in a time-resolved fashion after switching off excitation radiation to establish a decay function, representing the decay of the fluorescence intensity over time, for a multiplicity of pixels, comparing the decay functions associated with the pixels to at least one reference decay function to establish an error value for one or more pixels, the error value associated with a pixel being a measure for a deviation of the decay function associated with the pixel from the reference decay function, and generating an image of the sample using the error values.
