Color Speckle Measurement Software
Color Speckle Measurement & Analysis
Operation window of M-Speckle software
|We have launched brand-new color speckle measurement technology! Speckle noise of white screen on laser displays can be measured.|
Automatic red / green / blue speckle image capturing with filter wheel control option
Simulate color speckle distribution from the values of red / green / blue speckle contrast
Recalculate color speckle distribution by loading saved data of measurement mode
Two types of diagrams are selectable
*Below are the case of CR = CG = CB = 0.5
|CIE 1976 color system (u’, v’)||CIE 1931 color system (x , y )|
Evaluation metrics of color speckle distribution
- Covariance μu’v’ , variance σu’2 , σv’2 , and variance in a parallel or perpendicular direction to the line passing the light source point and the target chromaticity point in the CIE 1976 chromaticity diagram (u’, v’).
Photometric speckle contrast Cps = σy/⟨Y⟩ , where Y is the tristimulus value.
Pseudo-color view of speckle pattern image
Each Red / Green / Blue speckle pattern image can be displayed in pseudo-color. Combined RGB image display in pseudo-color is also possible.
