The authors develop a micro WAF lens suitable for a board lens camera with a 1/3 inch imaging chip. The prototype of this Micro WAF lens has a smaller diameter and length, i.e., φ8mm × 15mm, than half of those of the WAF lens that the author produced formerly, i.e., φ16mm × 32mm. However, its central field of view (FOV), called herein fovea, has a much higher resolution; that is, its projected image is more highly distorted than that projected by the former WAF lens. The central FOV is approximately 10% of the entire FOV within an incident angle of 2.5° in Micro WAF lens, whereas it is approximately 10% within an incident angle of 10° in the former WAF lens. We mainly focus on determining its specification as the first step of a lens design procedure and discussing the results simulated using the lens design software.本誌: IEEJ Journal of Industry Applications Vol.2 No.1 （2013） Special Issue on Motion Control and its Related Technologies本誌掲載ページ: 55-60 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejjia/2/1/2_55/_article/-char/ja/ Show more
