Abstract
In an embodiment an optical arrangement includes a multicore fiber having at least a first fiber core configured to guide a first illumination light and a second fiber core configured to guide a second illumination light, wherein the multicore fiber comprises a fiber scanner configured to deflect the multicore fiber or the multicore fiber is followed by a mirror scanner; and a wavelength dispersive beam combiner configured to spatially superimpose the first illumination light and the second illumination light in an object space.
Claims15
An optical arrangement comprising:
- a multicore fiber comprising:
- at least a first fiber core configured to guide a first illumination light;
- and
- a second fiber core configured to guide a second illumination light,
- wherein the multicore fiber comprises a fiber scanner configured to deflect the multicore fiber or the multicore fiber is followed by a mirror scanner;
- a wavelength dispersive beam combiner configured to spatially superimpose the first illumination light and the second illumination light in an object space;
- and
- a front lens group arranged between the wavelength dispersive beam combiner and the object space,
- wherein the optical arrangement is configured for imaging spectroscopy, and
- wherein the imaging spectroscopy is a Coherent Anti-Stokes Raman Scattering (CARS) spectroscopy or a Stimulated Raman Scattering (SRS) spectroscopy.

A spectroscopic imaging method comprising:
- guiding a first illumination light in a first fiber core of a multicore fiber and guiding a second illumination light in a second fiber core of the multicore fiber, wherein the first illumination light and the second illumination light comprise different wavelengths;
- spatially superimposing the first illumination light and the second illumination light superimposed by a wavelength-dispersive beam combiner in an object space, a front lens group being arranged between the wavelength dispersive beam combiner and the object space,
- wherein the multicore fiber is a fiber scanner or the multicore fiber is followed by a mirror scanner, and wherein the object space is scanned by a movement of the fiber scanner or the mirror scanner;
- and
- guiding an object light coming from the object space in a light conducting cladding of the multicore fiber in a direction of an evaluation unit,
- wherein the spectroscopic imaging method is a Coherent Anti-Stokes Raman Scattering (CARS) spectroscopy method or a Stimulated Raman Scattering (SRS) spectroscopy method.
