The invention relates to spectral imaging, in particular to imaging of spectral reflectance distribution at several fixed wavelengths using a single RGB image data set. In the proposed method for obtaining several spectral reflectance images, they are extracted from a digital RGB image data set at the wavelengths corresponding to those used at polychromatic illumination of the target, providing linearity of the photo-response, using the reference reflector and taking into account the overlapping of the RGB photo-detector spectral sensitivity bands, where the spectral reflectance is calculated for each image pixel or group of pixels using a calibrated grey reference reflector with reflection coefficients at all exploited wavelengths less than those of the white reference and by value is close to the largest reflection coefficient of the displayed object area. In case of different intensities of the illumination spectral lines, corrections for spectral reflectance values are proposed.
The invention relates to spectral imaging, in particular - to imaging of spectral reflectance distribution at a number of fixed wavelengths bands by means of a single RGB image data set. In the proposed method for obtaining a number of spectral reflectance images, the object and attached to it white reflector is illuminated simultaneously at a number of, for instance two or three, spectral bands, ensuring linearity of the photo-response, and the R;-, Gj- and Bj-signal values are identified for every image pixel "i", including those registered at the white reflector zone.

METHOD AND DEVICE FOR MULTI-SPECTRAL IMAGING BY MEANS OF A DIGITAL RGB SENSOR
The invention relates to methods of digital colour image processing, in particular - to selection of images corresponding to more than three different spectral bands from a single RGB data set. In the proposed method of multi-spectral imaging, the object is illuminated simultaneously at several spectral bands, and the values of Ri-, Gi- un Bi-signals detected at each i-pixel of the image are identified. Further they are compared mutually and with externally determined signal discrimination level S that allows registering only one or two of the R-, G- and/or B-bands within the spectral sensitivity range of the sensor. In order to increase the number of available spectral images, the S-values are continuously variable up to the highest of all possible signal values of the R, G or B band, with condition that linear photo-response of the RGB sensor is ensured. Depending on the S-value, two situations are analyzed - if two colour band signals are registered simultaneously (i.e. B and G, G and R or B and R), or if the signals are registered only at one colour band - and after logical analysis the spectral interval of the pixel-registered radiation is identified. Further each spectral image is formed from the pixels or pixel groups that correspond to a particular selected spectral range. A device for multi-spectral imaging to implement this method comprises a multi-spectral light source, objective-equipped digital RGB sensor, RGB data set storage device, convertor for converting the RGB data into a set of spectral intensities in accordance with the selected signal discrimination level, selector of images for selecting the images related to each particular spectral band, and the output device, e.g. PC-monitor.

The invention relates to fibre optics, particularly to the optical signal transmission through the end of optical fibre orthogonally to its symmetry axis, and can be applied in illumination engineering, phototherapy, fibre-optical endoscopy, laser surgery, optical tomography, optical instrument engineering and in other fields. The proposed side emitting/detecting optical fibre with total internal reflection surface sloped to the fibre axis and output/input plane parallel to the fibre axis is characterized in that the reflecting surface and the output/input plane are optically monolithically integrated at the end of optical fibre core by filling the space between the output/input plane and cylindrical lateral surface of the core in front of the reflective surface with material of the fibre core or with similar optically transparent material, at that the distance of the output/input plane from the fibre axis is equal or exceeds external radius of the fibre. The proposed configuration provides several technical advantages, particularly, smaller size (which is more convenient in use and reduces the optical material consumption), shorter light pass from/to the fibre core (which assures more precise localisation of the emitted/detected radiation at the contact surface, as well as enhanced radiation collection efficiency), solid optical assembly (which excludes radiation refraction during its deflection, minimizes optical losses and assures more safe operation), as well as makes possible to obtain qualitative optical contact with a planar surface, oriented parallel to the fibre axis, without any additional components.
