Abstract

Nowadays the use of lasers in medicine is becoming more and more popular. To improve the quality of operations, attempts by various researchers are being made to use lasers in cooperation with robotic systems. Fiber lasers have a high potential for combining due to the fact that the fiber is quit flexible and allows to deliver laser emission to the operated tissues without significant losses. To fulfil the potential of using lasers in cooperation with robots, it is necessary to evaluate the data of the reflected optical signal. In this research the dependence of an optical reflected signal from the distance to different surfaces was evaluated. Experiments were conducted on motorized setting bench Tesa TPS 500 with wavelength 470 nm of a diode fiber laser and the range of power from 0.1 W to 1.6 W. Different materials were chosen for their reflective and mechanical properties: metal surface, plexiglas, and flexible composition based on (C₁₂H₁₈O₉)_n. The experiments showed that the dependence of the sensor data on the distance to the surface has a nonlinear form, which can be divided into three characteristic areas. The first one, from 0 to 0.2 mm, carries tip contact with the surface information and has no clearly expressed dependence. The second one, situated at the distance from the surface from 0.2 to 1 mm, has well approximated dependence. The third one, when the distance is more than 1mm from the surface, obeys the law of inverse squares. The results obtained can be used to improve robotic laser contact or noncontact cutting of soft tissues.
