Abstract

A transmissive micro dihedral corner reflector array consists of numerous pairs of orthogonal surfaces that reflect light. Under such configuration, the object is imaged in mid-air with a 1:1 ratio, but with inverted depth. Despite some limitations, e.g., viewing angle, object position, or ghosting effect, the array is used for impressive 2D or 3D floating image projection. This work investigates the imaging quality of the commercially available plastic plate to quantitatively present the image deterioration. For this purpose, the set of experiments widely used for imaging optics testing is employed for a few typical arrangements. The evaluation includes resolving power, chromatic aberration, color reproduction, distortion, and uniformity.
