   Estimating scanning speed under a given X or Z resolution (G2xxx)

Question 

How can I estimate the scanning speed under a given X or Z resolution?

Answer 

Sensor Model G2xxx
Firmware Version 3.x, 4.x
SDK Version n/a

The scanning speed of Gocator is influenced by several factors, including exposure time/mode, resampling parameters, sub-sampling (in Gocator 4.x), X resolution (in Gocator 3.x), active area, etc. The most accurate way is to simulate the configurations on the Gocator, in which case the maximum scanning speed will be reported by the Gocator.

For active area adjustments, the X and Z sub-sampling (Gocator 4.x), the X and Z resolutions (Gocator 3.x), and the scanning speed will depend on whether the active area lies at the close end or the far end of the measurement range. If the active area lies closer to the sensor, the result will be a higher resolution and a slower scanning speed. If the active area is farther away from the sensor, the scanning speed will increase and the resolution will decrease. This is why resolutions are specified as a range in our datasheets, with the highest resolution at the closest point in the measurement range and the lowest resolution at the farthest point.
