Resolution and Range of Measurements
for
Holography, Speckle Correlation, and Projected Fringe Moiré

Holography

Wavelength= 532 nm q = 0
Minimum Theoretical Resolution = 1 nm
Practical Resolution (adjusted for noise) = 10 nm
Maximum measurement range for static mode = 26.600 mm  
Maximum measurement range for vibration mode = 1.330 mm   

Speckle Correlation

Wavelength= 532 nm  f = 30o
Mimimum Theoretical Resolution = 2 nm
Practical Resolution (adjusted for noise) = 21 nm
Maximum measurement range for static mode = 13.300 mm
Maxiumum measurement range for vibration mode = 2.660
mm

Projected Fringe Moiré

Object fills field of view of camera
Minimum theoretical resolution= Object width/256000
Practical resolution (adjusted for noise) = Object width/10000
Maximum range = Object width/4
