A smart fiber-optic sensor system for use with robotic surgical systems performs optical spectroscopy using a diffuse reflectance spectroscopy (DRS) sensing channel, a self-calibration (SC) channel, a pressure-sensing channel, and a temperature sensing channel. During use of the fiber-optic sensor during a laparoscopic procedure, the pressure-sensing channel ensures that the fiber-optic sensor is maintained in suitable contact with the target tissue being treated. In addition, the temperature sensor is used to ensure that the target tissue does not exceed a desired temperature from the use of an electrosurgical cutting device during the laparoscopic procedure, so as to prevent burning or charring damage at the target tissue.
