Method to eliminate pseudoscopic issue in integral imaging 3D display by using transmissive mirror device and light filter

We propose an optical method to eliminate pseudoscopic issue in integral imaging 3D display by using a transmissive mirror device (TMD) and a light filter. Object light rays passing through the TMD can form an undistorted and depth inverted real image. Therefore, the TMD can eliminate the pseudoscopic issue existing in the traditional integral imaging 3D display. However, two ghost images are appeared in integral imaging 3D display using the TMD. After studying the causes of the ghost images, a light filter is designed and fabricated to eliminate the ghost images. An integral imaging 3D display using the TMD is developed and it presents high quality 3D image without pseudoscopic issue.
