The algorithm was divided into four parts: analysis of trajectory curves including trajectory discretization and reference frame establishment,extraction of swept profiles including evaluation of velocity vectors on revolution generators and calculation of swept profiles at each discretized position,generation of envelop surfaces including the groupi.

The design of a scanning instrument for medical laboratory equipment based on the embedded PC;

Liver Scan using Multiple Detector Spiral CT;

Laser television with two-beam scanning;

Quantitative selection of nonlinear sweep parameters of vibroseis.;

Sweep technique plays an important role in Vibroseis system,the resolution of Vibroseis seismic prospecting is affected by the shape of the sweep signal′s auto correlation function.

The varying pitch helixes were constructed on the parameter equation,and were selected as sweep trajectory;the surface of the screw was enveloped on the generating method.
