    Abstract: A Fabry-Pérot tuneable filter device is described with reflecting elements separated by an optical path length to form an optical resonator cavity. A first actuator means is directly or indirectly coupled with a first reflecting element. And the first actuator means is configured to modulate the optical path length between first and second reflecting elements by a modulation amplitude to thereby sweep the optical resonator cavity through a band of optical resonance frequencies with a sweep frequency of 70 kHz or more. And the mechanical coupling between selected elements of the arrangement is sufficiently low such that when operated at the sweep frequency, the selected elements act as a system of coupled oscillating elements. In addition or alternatively, the first actuator means is directly or indirectly coupled with the first reflecting element so as to substantially drive the first reflecting element only.

    Abstract: At least one embodiment of the method is designed to create a two-dimensional image of a three-dimensional sample. The method comprises the following steps: provision of a wave-length-tunable light source (1) that emits primary radiation (P) with wavelengths that vary over time; sampling of location points of the sample (2) with the primary radiation (P); collection of secondary radiation (S), wherein the secondary radiation (S) is a part of the primary radiation (P) reflected by the sample (2); creation of an interferometer-based detection signal for a plurality of sample areas, each with at least one location point, using a detection unit (4), wherein the detection signal is created as a difference signal from two output signals of a beam splitter (61) that receives reference radiation (R) and/or secondary radiation (S) at two inputs, wherein the reference radiation (R) is a portion of the primary radiation (P) that is not guided to the sample (2); and determination of a brightness value for at least one of the sample areas from the associated detection signal, wherein the determination of the brightness values is not substantially based on the summation of the individual signal amplitudes of the results of a Fourier transformation.

    Abstract: Disclosed herein is a system (10) for measuring light induced transmission or reflection changes, in particular due to stimulated Raman emission. The system comprises a first light source (12) for generating a first light signal having a first wavelength, a second light source (14) for generating a second light signal having a second wavelength, an optical assembly (16) for superposing said first and second light signals at a sample location (18), and a detection means (24) for detecting a transmitted or reflected light signal, in particular a stimulated Raman signal caused by a Raman-active medium when located at said sample location. Here in at least one of the first and second light sources (12, 14) is one or both of actively controllable to emit a time controlled light pattern or operated substantially in CW mode and provided with an extra cavity modulation means (64) for generating a time controlled light pattern. The detection means (24) is capable of recording said transmitted or reflected light signal, in particular stimulated Raman signal, as a function of time.
