Abstract: Examples of this application disclose a method for measuring optical properties of a target. The method comprises illuminating the target with an illumination area with a display screen in contact with the target, and analysing signals reflected from the target and transmitted back through the display screen to a sensor positioned behind the display screen, to determine the optical properties of the target.

Abstract: The invention relates to a method for electromagnetic spectroscopy of a sample, the method comprising: - Delivering an excitation beam of electromagnetic radiation to a first portion of a sample to obtain emission, or elastic or inelastic scattering of photons, said photons having a wavelength in the visible range, from molecules forming the sample; - Illuminating the first portion of the sample with a visible light, said visible light being switched on and off at a first frequency, so that illuminated time intervals and non-illuminated time intervals of the sample are defined; - Detecting said emitted, or elastically or inelastically scattered photons having a wavelength in the visible range during said non-illuminated time intervals; and - Obtaining spectroscopy information from said detected emitted, or elastically or inelastically scattered photons. It also relates to a system for electromagnetic spectroscopy of a sample.

Abstract: The technical problem of the claimed group of inventions is to obtain a contrast optical image. The method includes an impact on a finger joint with a biocompatible immersion agent, the transmission of the joint by optical radiation is consistent over several wavelengths lying in the window of the transparency of biological tissues, registration of the corresponding images with using a digital camera located on the other side of the light source relative to the position of the joint, determining the image contrast is carried out within the framework of first-order statistics. The test area is immersed in an immersion agent for 8-10 minutes until skin tension is reached. Optical sensor for implementing the method has been suggested (Fig. 1).
