Abstract
A device may determine a calibration value for a spectrometer using light from a first light source; deactivate the first light source after determining the calibration value; perform measurement with regard to a sample based on the calibration value, wherein the measurement of the sample is performed using light from a second light source; determine that the calibration value is to be updated; and update the calibration value using the light from the first light source.
Claims20
A method performed by a device, comprising:
- determining a calibration value for a spectrometer using light from a first light source,
- wherein the first light source is internal to the spectrometer;
- deactivating the first light source after determining the calibration value;
- performing, using light from a second light source, measurement of a sample based on the calibration value and after deactivating the first light source;
- determining that the calibration value is to be updated based on a threshold being satisfied,
- wherein the threshold is a threshold temperature change, a threshold number of measurements, a threshold length of time since a last update, or a threshold deviation of a measurement from an expected or previous value;
- activating the first light source based on determining that the calibration value is to be updated;
- and
- updating the calibration value using the light from the first light source after activating the first light source.
6 more elements
A device, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:
- determine a calibration value for a spectrometer using light reflected from a first light source of the spectrometer to a sensor of the spectrometer,
- wherein the light is reflected from a diffuser of the spectrometer to the sensor;
- deactivate the first light source after determining the calibration value;
- perform, using light from a second light source that is received via the diffuser, a measurement of a sample based on the calibration value and after deactivating the first light source;
- determine that the calibration value is to be updated based on a threshold being satisfied,
- the threshold being a threshold temperature change, a threshold number of measurements, a threshold length of time since a last update, or a threshold deviation of a measurement from an expected or previous value;
- activate the first light source based on determining that the calibration value is to be updated;
- and
- update the calibration value using the light from the first light source after activating the first light source.

A non-transitory computer-readable medium storing one or more instructions, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a spectrometer, cause the one or more processors to:
- determine a calibration value for the spectrometer using light from a first light source;
- deactivate the first light source after determining the calibration value;
- perform, using light from a second light source, measurement with regard to a sample based on the calibration value and after deactivating the first light source, wherein the measurement of the sample is performed using light from a second light source;
- determine that the calibration value is to be updated based on a threshold being satisfied,
- wherein the threshold is a threshold temperature change, a threshold number of measurements, a threshold length of time since a last update, or a threshold deviation of a measurement from an expected or previous value;
- and
- update the calibration value using the light from the first light source.
