Abstract
An approach is proposed to determine the phase-shifting value in phase-shifting digital holography.By employing a random phase plate behind the object,we successfully made the phase distribution of the object on the holography plane a spatially approximation random distribution.Then an algorithm utilizing this character to extract phase-shifting value is proposed.Computer simulations indicate that the extracted phase-shifting value is very close to the predetermined,and the relatively error is less than 0.1%.At the same time,by comparing the calculation results with and without the random phase plate,we find that the phase distribution of an object has some correlation after diffraction.
