Abstract

Compound-eye imaging-system [1] developed in the field of information photonics has wide versatility, and various applications using compound-eye imaging-system have been proposed. Gonio-imaging of OVDs such as security holograms in the field of forensic document examination is one of the applications of the system [2]. In this study, we constructed compound-eye imaging systems with coaxial illumination unit, and demonstrated gonio-imaging of handwritten strokes.
