Data Archive for "Speckle Noise Reduction via Linewidth Broadening for Planetary Laser Reflectance Spectrometers"

This archive contains the raw speckle images and experimental notes for the data contained in the journal article: "Speckle Noise Reduction via Linewidth Broadening for Planetary Laser Reflectance Spectrometers".

The data available are:

Raw speckle images for each of 5 illumination sources:

Single-Frequence diode (files are named "IPS")

Dual Mode pump diode (files are named "II-IV")

Fabry Perot didoe (files are names "FP")

Superluminescent Diode (files are named "SLD")

Whilte light halogen source (files are named "WL")

For each of theses source there are 5 images for each reflectance target, four speckle patterns and one background image with the laser source off. The naming convention is:

LaserName_TargetReflectance_Target Rotation State or BKG.tiff

For example, IPS_50_2 is the single-frequency laser using the 50% reflectance target and second rotation state of the target.

The integration time for each image is give in the file "Experiment Paramters.csv" and was manually change to keep the maximum intensity at roughly 75% saturation.

The spectra of the three laser sources presented in the manuscript are also included as .csv files
