Optical EngineeringMapping algorithm for 360-deg profilometry with time delayed integration imaging
|Format||Member Price||Non-Member Price|
A direct phase-to-radial distance mapping algorithm for 360 deg profilometry with time delay and integration (TDI) imaging is presented. This method, based on an inherent mapping relationship, is capable of speedy and accurate measurement without the determination of any geometric parameter. The capability of the mapping algorithm is demonstrated by measuring a plane and a shoe.
