## Summary

To demonstrate our method for extrapolating full, depolarizing Mueller
matrices from fewer than 16 measurements, we measured an ensemble of roughened
plastic bricks using a Mueller imaging polarimeter and a linear Stokes camera.
The Mueller matrix images from the Mueller imaging polarimeter and the images
taken with four polarizer orientations from the linear Stokes camera are
included.

## Files and Folders

The data files located at the lowest levels of these folders are Real32 type binary files and are named according to the convention: BlueBricks_#aoi#_#aos#.bin, where #aoi# is the angle of incidence in degrees and #aos# is the angle of scattering in degrees.

Mueller_Matrix_Data.zip: Mueller matrix images of the roughened LEGO bricks measured with a Mueller matrix imaging polarimeter.
- 451 nm: Folder containing measurements taken at 451 nm. 
- 662 nm: Folder containing measurements taken at 662 nm.

The data of each file are organized by: 
    pix(1,1)_MM(1,1), pix(1,1)_MM(1,2), ..., pix(1,1)_MM(4,3), pix(1,1)_MM(4,4), pix(1,2)_MM(1,1), ..., pix(200,200)_MM(4,4) 
where pix(x,y) indicates the pixel number x,y and MM(i,j) indicates the Mueller matrix element i,j.

Stokes_Camera_Data.zip: Images taken with a commercial linear Stokes camera. 
- 451 nm: Folder containing measurements taken at 451 nm.
- 662 nm: Folder containing measurements taken at 662 nm.

The data of each file are organized by: 
    P(0)_pix(1,1), P(0)_pix(1,2), ..., P(0)_pix(341,341), P(45)_pix(1,1), ..., P(45)_pix(341,341), P(90)_pix(1,1), ..., P(90)_pix(341,341), P(135)_pix(1,1), ..., P(135)_pix(1,1) 
where P(q) indicates the measurement with polarizer angle q in degrees and pix(x,y) indicates the pixel number x,y.

BlueBricks_-10_10_MM_662nm.jpg: Preview image of the data contained in Mueller_Matrix_Data/662nm/BlueBricks_-10_10.bin.

Sample_code_Stokes_camera.R: Sample R code to read and display the binary data (created by ReDATA staff).
