FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine. System for optic measurement by means of optic coherence tomography (OCT) of internal dimensions of eye-containing examined object, with object possessing internal borders of division on which refraction index changes, with system being implemented with possibility of detecting part of incident radiation, reflected and/or dispersed by said borders in opposite direction. System contains first OCT-device (OCT1), made with possibility of measuring internal dimensions in first volume, representing part of object, and second OCT-device (OCT2), made with possibility of measuring internal dimensions in second volume, representing part of the same object, with said second volume being different from first volume. OCT 1 is made with possibility to emit first beam (B1) of first emission and has first longitudinal resolution (Δz1∞(λ1)2/Δλ1), specified by wavelengths of first emission, located in first interval of wavelengths, specified by first working wavelength (λ1) and first band width (Δλ1). OCT2) is made with possibility of emitting second beam (B2) of second emission and has second longitudinal resolution (Δz2∞(λ2)2/Δλ2), specified by wavelengths of second emission, located in second interval of wavelengths, specified by second working wavelength (λ2) and second band width (Δλ2). First longitudinal resolution (Δz1) is higher than second longitudinal resolution (Δz2). Method of optic measurement of internal dimensions of incident radiation object includes detection of radiation, reflected back and/or dispersed in opposite direction and measurement in the course of single measuring operation of dimensions in first volume and dimensions in second volume. Second volume is different from first volume.
EFFECT: application of claimed group of inventions will make it possible to perform precise individualised processing.
