Abstract

The authors have developed the wide angle fovea (WAF) telescope. This development was originally motivated from our mind to assist the ranger to save the people floating on the sea. Cruel Tsunami disasters often cause such miserable situations. An objective lens part of this special telescope was formerly developed using the Advanced WAF (AdWAF) model, by which we can design a distribution of the lens curve very flexibly. This special-made objective lens has an enough wide field of view, and thus it can keep a moving target as being always inside field of view. In addition, it can observe the target more in detail because its central field of view has higher magnification than the conventional telescope. Yes, this telescope is inspired from a smart function of the human eye to improve its availability. This special-made objective lens achieves not only wide-angle surveillance and but also detailed observation on the same time. Moreover, a special-made eyepiece lens part is also designed for users to observe environments with a more immersive feeling. This eyepiece utilizes a broader area on the human retina for the WAF telescope image projection. Indeed, the developed telescope has 22 aspherical surfaces of all 28 surfaces by using economy plastic lenses.
