摘要：
A phase shifted digital projection system has been developed for shape measurement. The projection grating is computer generated. The profile and pitch of the grating can be readily varied using software. Gratings of sinusoidal, square and triangular intensity distributions with different pitches were generated to study the effects of grating pitch and profile on the performance of the system.
