Experimental Study on the Resolving Power of the Pinhole Camera

〜Making a Pinhole Camera Capturing a Lunar Crater〜

Abstract

It is known to be the optimum caliber for a pinhole camera. In this study, first, the existence of the optimum caliber was verified using digital pinhole cameras. Next, the relationship between the focus length and the resolving power was experimentally clarified. In addition, a pinhole camera with more than 4m of projection distance was developed to take a picture of the lunar craters, and we actually succeeded in filming the craters.
