Abstract

Inventia se refera la optoelectronica, in special la un aparat de scanare ńu radiatie laser a cavitatilor, si poate fi utilizata in medicina. Aparatul de scanare a cavitatilor ńu radiatie laser include o carcasa transparenta de forma tubulara cu un capat inchis, un reflector plasat in interiorul ei si o fibra optica amplasata coaxial cu carcasa. Aparatul suplimentar contine o bucsa amplasata liber in interiorul carcasei in asa mod incat gulerul de sprijin este situat in exterior, iar pe partea laterala sunt realizati niste dinti cuplati cu o roata dintata montata pe arborele unui motor electric reversibil conectat la o sursa de curent continuu. Pe partea frontala a bucsei, amplasata in interiorul carcasei este executata o proeminenta pe care este fixat un suport, pe axul de intoarcere al caruia este fixat articulat reflectorul cu suprafata din material dielectric. Axul de intoarcere este cuplat cu un element ce se deplaseaza rectiliniu alternativ fiind unit de partea opusa cu un surub de pozitionare si conectat electric prin intermediul a doua contacte inelare, montate pe partea laterala a bucsei, cu contactele generatorului de curent cu amplitudine si frecventa reglabile fixate pe carcasa. Carcasa, de partea capatului inchis, este inzestrata suplimentar cu un invelis pelicular amobil, transparent pentru radiatia laser. ŕThe invention relates to optoelectronics, especially to a cavity laser scanning and radiation apparatus, and may be used in medicine. The laser scanning cavity scanner includes a tubular-shaped transparent casing with a closed end, a reflector placed inside it, and a fiber optic coaxially located with the casing. The additional device contains a bushing freely located inside the housing so that the support collar is located on the outside, and on the side are made some teeth coupled with a gear wheel mounted on the shaft of a reversible electric motor connected to a DC power source. On the front of the bush, located inside the housing, a projection is executed on which a support is fixed, on the return axis of which the articulated reflector with surface of dielectric material is fixed. The return axis is coupled with an alternating rectilinear moving element being joined by the opposite side with a positioning screw and electrically connected via two ring contacts, mounted on the side of the bush, with the current generator contacts with adjustable amplitude and frequency. fastened to the housing. The housing, on the side of the closed end, is additionally endowed with a movable, transparent film coating for laser radiation. à
