Abstract
Techniques for calibrating an optical sensor system of a composition identification system are provided. In an example, a method can include receiving light at an optical sensor of the optical sensor system from a reference target, determining a first spectral response of the light across a range of wavelengths, determining whether a first spectral intensity corresponding to a first wavelength of the spectral response violates a first threshold, adjust an exposure duration or gain of the optical sensor for the first wavelength to correct the violation, and repeat for multiple wavelengths in the range. Once calibrated, the optical system can more efficiently identify composition of targets, such as anatomical targets encountered during medical procedures such as during endoscopy, laparoscopy, or ureteroscopy procedures, especially when such targets are illuminated with a wide spectrum illumination source.
