摘要：
The proposed technical solution (Utility Model) relates to devices other than the optical measuring means, in particular to the interferometers and may be used in human and veterinary medicine for diagnostic measurements and in physics research or for materials analysis by optical means. An object of the utility model is to increase the spatial resolution due to complex reduce the useful signal losses associated in particular with errors in synchronization of a plurality of interference signal detector (a useful model of only one such detector, or rather its kind - balanced photodetector) and the converting process the optical signal into an electrical (in the utility model by an amplifier and a filter, and an analog-to-digital converter). The stated technical problem is achieved by the apparatus of differential optical coherent tomography, as well as in the device which is the closest analogue, contains two radiation sources, two separator plates, optical mixers, balanced photodetector, support arm, a sample arm and a processing unit data and forming a tomographic image, both the radiation source generates a unique wavelength radiation and have separate outputs for it, and the optical mixer is optical communication with the reference arm and the sample arm. The novelty of the developed device of differential optical coherent tomography is that the two separating plates are in optical communication with the optical mixer support arm comprises a rigidly jointed optical delay line and a collimating lens, wherein the optical delay line is fixed at the focal distance of the lens and stored with it in optical communications, the shoulder of the sample contains are in optical communication galvano scanner and a focusing lens, a mirror and galvano-scanner is placed in a flat STI focal length of the focusing lens in such a way that for any rotation galvano scanner mirror focal length maintained, both separator plates also optically connected to the inputs of the balanced ph
