hi,

In the SDK OPT3101_Calibration.cpp file, there is Void OPT3101::device::calibrationSession_perUnitFactoryCalibration () method implementation, see "refDistanceInCodes = (refDistanceInMM[indx] * 4477) >> 10; ", some doubts, how is the "4477" calculated?

Hi Dongming,

4477>>10 is a truncated version of 4477/2^10 = 4.372...

4.372 is for mm units and comes from the distance formula to go between meters and codes: 2*10MHz*2^16/c = 4372...

Best,

Alex
