The author invented and developed a technique capable of three-dimensional image measurement for moving objects. The technique has been called as parallel digital holography and carries out phase-shifting interferometry simultaneously using space-division multiplexing of the reference wave in digital holography. The space-division multiplexing is implemented by a phase-shifting device array. The validity of the technique was confirmed by a preliminary experiment. It was also confirmed that the microscopy using this technique is capabile of three-dimensional image measurement of cells.
