Parameters used with this code in the Shevell Lab. :


Measured for our particular CRT.
(The first column is lambda, the 3 others are respectively the R, G and B phosphors distribution)

Standard Judd (1951) X,Y,Z.
(The first column is lambda, the 3 others are respectively xbar, ybar & zbar)

Calibration information for our particular CRT
  • Zernike Coefficients
3mm pupil
4.5mm pupil
6mm pupil
Zernike coefficients used to model the wave aberration
From the paper "A Statistical Model of the Aberration Structure of Normal, Well-Corrected Eyes"
Larry N. Thibos, Arthur Bradley, Xin Hong, Itself based on the Indiana Aberration Study (IAS) :
"Statistical Variation of Aberration Structure and Image Quality in a Normal Population of Healthy Eyes", Larry N. Thibos, Xin Hong, Arthur Bradley, Xu Cheng.

Here are some other parameters:
SPD (2)      Judd Specs (2)

The CreateStimulus package allows to create simple shapes as circles, squares, rectangles or sinewaves and stores the outpupt images as simple matrices without any header. Evidently, you can use any other existing software (such as Matlab, Adobe Photoshop, Adobe Illustrator, etc) to create these shapes.
 If you want to pick up existing configuration files to create your stimulus with the CreateStimulus package, download CFG_Files.

Using your own calibration parameters:
 You just have to replace the above Judd Specs and Spectral Power Distribution by yours, and hopefully, it should work...
