We present an improved two-in-one polarization-interlaced liquid-crystal-on-silicon (LCoS) stereoscopic projection prototype employing a novel prism-array configuration and a specially designed illumination freeform lens group. The parallel prism configuration is designed based on the balance analysis between stereoscopic channels. For further system simplification, the illumination lens group, which consists of three prepositive aspherical surfaces and a single postpositive freeform one, is synthetically obtained from the Monge-Ampère method and feedback optimization. Design results show that the proposed prototype can well solve the problem of stereo-channel separation and integration, and provide both better performance and lower volume. It is proven to have potentiality replacing existing stereoscopic projectors.
