Through the absolutephasemeasurement of the master object, different inverse fringes are generated for the different projectors placed in different directions.
通过测量标准样品的绝对相位,为不同角度放置的投影器产生不同的反向条纹。

Absolutephasemeasurement and phase reconstruction to object surfaces with complex geometric and topologic shapes still remain difficult for phase mapping based on three-dimensional (3d) sensing.
