SPECTRAL_GROUP
Encompasses groups of categories applicable to spectral imaging data.
SPECTRAL_SPECTRUM
Data items in the SPECTRAL_SPECTRUM category record the results of the spectrum measurements.
_spectral_spectrum.wavelength
The wavelength value at the given spectrum point.
Units: nanometres
_spectral_spectrum.relative_reflectance
The relative reflectance at the given spectrum point.
Units: arbitrary_units
SPECTRAL_MEASUREMENT
The CATEGORY of data items that specify the overall spectral imaging measurement information.
_spectral_measurement.environment
The environment that the measurement was conducted in.
Values:
| Value | Description |
|---|---|
| air | Air. (default) |
| reducing_conditions | Reducing conditions. |
| other | Environment not in this list. |
_spectral_measurement.environment_details
Human-readable description of the measurement environment given as the _spectral_measurement.environment data item value.
_spectral_measurement.datetime_initiated
The date and time (timestamp) recorded at the start of the measurement experiment. The timestamp should preferably be expressed as specified in RFC 3339, however, a date only time (YYYY-MM-DD) is also acceptable.
_spectral_measurement.datetime_terminated
The date and time (timestamp) recorded at the end of the measurement experiment. The timestamp should preferably be expressed as specified in RFC 3339, however, a date only time (YYYY-MM-DD) is also acceptable.
_spectral_measurement.pressure
The pressure at which the sample was measured.
Units: kilopascals
_spectral_measurement.temperature
The temperature at which the sample was measured.
Units: kelvins
_spectral_measurement.integration_time
The exposure time spent acquiring a single spectrum.
Units: seconds
SPECTRAL_MEASUREMENT_DEVICE
The CATEGORY of data items that specify the spectra measurement device information.
_spectral_measurement_device.location
The physical location of the device at the time of the measurement.
_spectral_measurement_device.company
The name of the company that produced the measuring device.
_spectral_measurement_device.model
The model of the the measuring device.
_spectral_measurement_device.serial_number
The serial number of the the measuring device.
_spectral_measurement_device.details
Human-readable description of the measurement device.
_spectral_measurement_device.camera_type
The camera type of the measuring device.
Values:
| Value | Description |
|---|---|
