<p>Systems and methods for analyzing a sample are disclosed. The system may include a light source operable to transmit light onto the sample, a detector operable to detect intensity of the light emitted from the sample, and a power modulator. The power modulator modulates the light source power such that light is emitted from the light source in more than one mode to reduce changes in the emitted light due to temperature changes in the light source.</p> |
