  4. Notes on future development

1. Published Paper

Terahertz correlation spectroscopy infers particle velocity and rheological properties Eric J. Rees, Ke Su, and Axel Zeitler

Opt. Lett. 41(14), 3289-3292 (2016)

Optics Letters: https://www.osapublishing.org/ol/abstract.cfm?uri=ol-41-14-3289 doi: 10.1364/OL.41.003289

Openaccess.cam identifier and url: OA-8992 https://www.repository.cam.ac.uk/handle/1810/256542

2. Sample data:

Sample data for the THz Correlation Spectroscopy paper is archived at:

data.cam: https://www.repository.cam.ac.uk/handle/1810/254844

This data (~600 MB) is needed to run the script that generates the published figures

3. Matlab code for data analysis.

(a) THz_Corr_Vel_Code_Figs.m

This script generates all the figures that present data in the paper.

This script was developed in Matlab 2013b.
It reads in raw sample data from the opendata folder.
To use this script, open Matlab, set the opendata folder as the working
directory, and run this script.

(b) TOF.m

Time-of-flight analysis

Analyses viscometer data to produce time-and-depth resolved
velocimetry results using the terahertz correlation spectroscopy
method presented in the paper.

(c) NOT INCLUDED IN THIS FOLDER - but useful for making greyscale compatible figures in the paper:

cubehelix.m
Implement's Dave Green's cubehelix colormap.
Used for Figure 4.
Cubehelix is a colormap with maximised constrast that can be
converted to grayscale without loss of information.
The cubehelix colormap is fully presented in:
Green, D. A., 2011, `A colour scheme for the display of astronomical intensity images', Bulletin of the Astronomical Society of India, 39, 289.

  2. Sample data
  3. Matlab code for sample data analysis
  4. Notes on future development
1. Published Paper
Terahertz correlation spectroscopy infers particle velocity and rheological properties
Eric J. Rees, Ke Su, and Axel Zeitler
Opt. Lett. 41(14), 3289-3292 (2016)
Optics Letters: https://www.osapublishing.org/ol/abstract.cfm?uri=ol-41-14-3289
doi: 10.1364/OL.41.003289
Openaccess.cam identifier and url: OA-8992
https://www.repository.cam.ac.uk/handle/1810/256542
2. Sample data:
Sample data for the THz Correlation Spectroscopy paper is archived at:
data.cam: https://www.repository.cam.ac.uk/handle/1810/254844
This data (~600 MB) is needed to run the script that generates the published figures
3. Matlab code for data analysis.
(a) THz_Corr_Vel_Code_Figs.m
This script generates all the figures that present data in the paper.
This script was developed in Matlab 2013b.
It reads in raw sample data from the opendata folder.
To use this script, open Matlab, set the opendata folder as the working
directory, and run this script.

(b) TOF.m
Time-of-flight analysis
Analyses viscometer data to produce time-and-depth resolved
velocimetry results using the terahertz correlation spectroscopy
method presented in the paper.

(c) NOT INCLUDED IN THIS FOLDER - but useful for making greyscale compatible figures in the paper:
cubehelix.m
Implement's Dave Green's cubehelix colormap.
Used for Figure 4.
Cubehelix is a colormap with maximised constrast that can be
converted to grayscale without loss of information.
The cubehelix colormap is fully presented in:
Green, D. A., 2011, `A colour scheme for the display of astronomical intensity images', Bulletin of the Astronomical Society of India, 39, 289.
