1. A method comprising:
- measuring transmitted light from a body for at least one wavelength band via a first optical system;
measuring scattered light from the body for the at least one wavelength band via a second optical system;
determining a substance concentration in the body based on a predetermined correlation between measurement data and the substance concentration, the measurement data being associated with the measured transmitted light and the measured scattered light.

Abstract
A system includes a light source and a light detector. The system further includes a first optical system configured to direct a transmitted portion of light onto the detector. The first optical system is further configured to block a scattered portion of the light. The system also includes a second optical system configured to direct the transmitted and scattered portions of the light onto the detector.
