Pinhole images physics
WebUnlike a lens, a pinhole or other small opening can focus light coming from any distance. Because it's such a small opening, it only allows light to come through in one place, and thus in only one direction from any particular source. So there's no blur and everything is in focus. WebPHYSICS PROJECT REPORT ON PIN HOLE CAMERA. A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole – effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.

WebIn a pin-hole camera there's no blurriness possible, as long as the hole is small enough, each point opposing the hole is mapped onto one specific ray. This means this type of camera can never have a blurry image, no matter where it's … WebA pinhole camera is a camera without a lens.

WebVince Huegele, an optical physicist at the NASA Marshall Space Flight Center, explains the modern understanding: "Solar images formed by pinholes, crossed fingers, patches between leaves, all occur because of diffraction--a wave property of light. In the case of a pinhole, the light rays do not shoot straight by the rim of the hole, but bend ...
