| Abstract: | A new method to measure LCTV’s phase modulation characteristics is suggested in this paper.The fringe pattern of step wavefront based on cyclic radial shearing interferometer has been explained.And the phase modulation characteristics of EPSON13VM125 has been measured.It show that method can be used to measure whole LCTV’s phase modulation characteristics in accuracy and rapidly. |
