FIELD: medical equipment.
SUBSTANCE: group of inventions relates to medical equipment, specifically to means of diagnosing corneal degeneration. System comprises an optical coherence tomography (OCT) device, which is configured to emit a first light beam having first wavelength (λ1), a Brillouin scattering (BS), spectrometer, which is configured to emit a second light beam having second wavelength (λ2), different from first wavelength (λ1), a beam combiner, which is configured to combine the first light beam and the second light beam such that, the first light beam and the second light beam propagate along the same optical path towards a cornea, a beam guiding and focusing device, which is configured to focus the first light beam and the second light beam together at a predetermined position (x,y,z) on or in the cornea, a control and analysis device for scanning the directional orientation (kx,ky,kz) of the first light beam and the second light beam such that, that the first light beam and the second light beam are focused (x,y,z) on or in the cornea. OCT device is further configured to interferometrically analyse the first light beam backscattered from the cornea via the beam combiner to provide OCT data representing a position dependent structural property of the cornea, wherein the BS spectrometer is further configured to spectroscopically analyse the second light beam backscattered from the cornea via the beam combiner to provide BS data representing a position dependent frequency shift (fB(x,y,z)) of a Brillouin scattering caused by the side band of the backscattered second light beam. Method for diagnosing corneal degeneration is carried out using the system.
EFFECT: use of inventions allows early detection of corneal degeneration, which affects the biomechanical stability of the human cornea.
