“…This apodization is found to be useful for improving the evaluation accuracy of the projected image's resolution. 9 Also, we made the incident diameter of the refractive lens small (cf. Table 1) by employing a non-telecentric optical interface between the illumination optics and the projection optics.…”

Abstract— This paper presents a new optical system used in an ultra‐thin rear projector with a 1500‐mm diagonal size and 260‐mm depth. A refractive‐reflective optical system was developed to achieve a large projection angle of 136° with a small optical distortion of 0.1%. The optics consists of a convex aspherical mirror and a refractive lens. In addition, a new Fresnel screen composed of hybrid blades of refractive‐TIR (total internal reflection) elements was developed to attain good uniformity of brightness and color within the image area.
