Spacial resolution

I can't find any information about the Intel F200 camera's spacial resolution and accuracy.

What's the smallest distance between 2 scanned points in the X, Y and Z (depth) directions, for the minimal (0.2 m) and maximal (1.2 m) ranges ?

What's the accuracy of these distances ? (3 sigma error in mm, or any other way to specify it)

Does this accuracy depend on the light conditions (which can generate more or less noise) ? and speed (which can generate bury pictures...) ?

Z(depth) accuracy is less

Z(depth) accuracy is less than 1mm.

Well, I did some experiments

Well, I did some experiments and unfortunately I got different results (Just created a topic about different accuracies of two f200 sensors)

Because the two sensors have different accuracies in my experiments I cannot not give consistent results. But below you can find my results for one test setup for both sensors. The real distance is measured with an accurate laser distance measurement device (don't know the correct English term for that device) from Holex. I repeated the test multiple time and got different results at each run. But the one sensor is always better than the other, although they share the same firmware.
