METHOD FOR OBTAINING THE IMAGE OF AN OBJECT, DEVICE FOR CARRYING OUT SAID METHOD AND DEVICE FOR DELIVERING LOW COHERENT OPTICAL RADIATION

The invention relates to the study of the internal structure of objects with the aid of optical means. The inventive optical system for a device for delivering low coherent optical radiation is embodied in the form of at leas t two lens components (19, 20) which are arranged approximately confocally and have a positive optical power, thereby ensuring the constancy of the travel time of the radiation from a set point on a surface (28) of a transverse scanning to a corresponding conjugate point on an image plane. The structure of the system also ensures the correction of the aberration of the optical path of the radiation which is directed towards a studied object, said aberration being associated with a transverse scanning irrespective the surface (28) thereof is flat or curved. In another embodiment of the system, wherein the components (19, 20) are arranged confocally, the longitudinal scanning is carried out by modifying the optical path of the radiation from the surface (28) to the optical system, i.e. from the end surface (17) of th e distal section of an optical fibre to the optical system. For this purpose, a device (10) for longitudinal scanning is arranged inside an optofibre probe, thereby making it possible to offset accordingly the radiation focusing poin t during the longitudinalscanning of the studied object, i.e. make it possible to superpose the position of the radiation focusing point with the position of a coherence window, and therefore simultaneously displace them.
