Detailed Description

Internal class encapsulating a 16-bit set of boolean flags which indicate whether a given spectrometer has a particular feature or not.

Requires less storage than legacy hasCooling, hasLaser or hasBattery fields.

Member Data Documentation

bin2x2

bool WasatchVCPP::FeatureMask::bin2x2 = false

Some 2D detectors use a Bayer filter in which pixel columns alternate between red and blue sensitivity (green is uniform throughout).

By binning square blocks of 2x2 pixels (for any given detector position, this would include 1 blue, 1 red and 2 green), an even sensitivity is achieved across spectral range.

As "vertical binning" is normally performed within firmware, the only portion of this 2x2 binning which is performed within the software driver is the horizontal binning. This is currently performed within Spectrometer.getSpectrumRaw.

invertXAxis

bool WasatchVCPP::FeatureMask::invertXAxis = false

The orientations of the grating and detector in this spectrometer are rotated such that spectra are read-out "red-to-blue" rather than the normal "blue-to-red".

Therefore, automatically reverse the spectrum array. This EEPROM field ensures that, regardless of hardware orientation or firmware, spectra is always reported to the user FROM WASATCH.NET in a consistent "blue-to-red" order (increasing wavelengths). This is the order intended and assumed by the factory- configured wavelength calibration.

The user should not have to change behavior or process spectra differently due to this value; its purpose is to communicate state between the spectrometer and driver and ensure correct internal processing within the driver.
