1. A method of operating an electrosurgical instrument, the method comprising:
generating an electrical discharge at an electrode to incise biological tissue;
recording light emitted as a result of the electrical discharge contacting the biological tissue during the incision;
increasing the intensity of the recorded light to produce an intensified recorded light; and
performing a spectral analysis of the intensified recorded light to determine a tissue type of the contacted biological tissue.
