WebDetermining the focal length based on the pinhole size: Once you have a pinhole created, you can determine the distance the film needs to be placed at to get a clear image. The formula is: focal length = (pinhole diameter / 0.03679) ^ 2 , units are in mm. Example: focal length = (0.3mm / 0.03679) ^ 2 focal length = (8.17438) ^ 2 focal length = 66.49mm … WebPinhole Lens Cameras.

WebBecause we know the light ray from captured object (x0,y0) comes through the pinhole (0,0), the change in horizontal direction is x0 - 0 and on vertical y0-0. The slope of the ray of captured object is therefore x0/y0. And because the point (x1,y1) on the image plane is the same light ray, therefore it lies on the same line as the captured ...
