WebHere is how 1.56 is derived: The optimal pinhole size is when geometric blur is equal to the diffraction blur. For far objects the geometric blur = pinhole size and diffraction blur = Airy disk d, d = 2.44 * L * f#, where L is the wavelength. Recall that f# = f/D and that we want d=D therefore we get: d^2 = 2.44 * L * f. WebFigure 2: A formal construction of the pinhole camera model. A more formal construction of the pinhole camera is shown in Figure 2. In this construction, the lm is commonly called the image or retinal plane. The aperture is referred to as the pinhole Oor center of the camera. The distance between the image plane and the pinhole Ois the focal ...
