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

We propose an optical method to eliminate pseudoscopic issue in the integral imaging three-dimensional (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. However, two ghost images appeared in integral imaging using the TMD. After studying the causes of the ghost images, a light filter is designed and fabricated to eliminate the ghost images. Integral imaging using TMD is developed, and it presents a high quality 3D image without a pseudoscopic issue.
