Claim Text:
1. A method of measuring characteristics of an electrosurgical device, comprising: projecting light through a light transmissive member including a plurality of segments, the plurality of segments configured to reflect at least one wavelength of light and transmit at least one wavelength of light, the light transmissive member disposed in at least one finger-mountable annular member of a pair of finger-mountable annular members; measuring a first wavelength of light transmitted through the light transmissive member; applying a force upon the light transmissive member causing a change in a spacing between the plurality of segments of the light transmissive member; measuring a second wavelength of light transmitted through the light transmissive member in response to the applied force; and comparing the first wavelength of light and the second wavelength of light to determine a change in the spacing between the plurality of segments as a result of the applied force.
