ABSTRACT:
The present invention discloses herewith measuring apparatus for measuring the dimension of an object or the distance to said object, said measuring apparatus utilizing an optical characteristic of a focusing glass fiber, a line or a circle or a focus being indicated on said object. The invention comprises a rod lens composed of said focusing glass fiber of suitable length, a non-diffusive light beam, for example a laser beam, being fed to the radial side of said rod lens, said light beam being scattered radially by said rod lens, said scattered light beam being applied to said object directly or by way of reflecting means, and a line or a circle or a focus is indicated on said object. By these provisions, the dimension of the object, for example a cancer in a body cavity, can be easily measured in order to observe time transfiguration of said cancer. In addition, the distance to bleeding position can be correctly measured in order to adjust an output of a laser surgical instrument.
