Systems and methods for determining a sensor power ratio

A calibration system, comprising:

• a sensor comprising:
• a light emitter to emit a first light and a second light;
• and
• a light detector to detect the first light and the second light;
• and
• a calibration structure;
• calibration processing circuitry;
• and
• a calibration memory comprising instructions that, when executed by the calibration processing circuitry, cause the calibration processing circuitry to:
• instruct a first light-emitting diode (LED) of the light emitter to emit the first light at a first wavelength and a second LED of the light emitter to emit the second light at a second wavelength;
• receive a signal indicative of the first light at the first wavelength and the second light at the second wavelength;
• determine a first power at the first wavelength and a second power at the second wavelength based on the signal;
• and
• determine a power ratio as a ratio of the first power and the second power.

A method for utilizing storage on a sensor, the method comprising:

• placing a first emitter of a sensor and a second emitter of the sensor at a calibration structure;
• instructing the first emitter to emit light into the calibration structure at a first wavelength and the second emitter to emit light into the calibration structure at a second wavelength;
• receiving a signal indicative of light detected at the calibration structure;
• determining, based on the received signal, a first power at the first wavelength and a second power at the second wavelength;
• determining a power ratio based on the first power and the second power;
• transmitting the power ratio to the sensor for storage in a memory of the sensor.
