Optical pinhole projector

WebI built an optical projector to observe the Venus transit with a 10x50 monocular. I mounted the monocular inside a box, leaving a small window to observe the projection. The focusing capability of the monocular was necessary to get a good image. The Sun's image was large and bright and detailed, much better than a pinhole projector.

WebLens distortion is a deviation from the ideal projection considered in pinhole camera model. It is a form of optical aberration in which straight lines in the scene do not remain straight in an image. Examples of lens distortions are barrel distortion and pincushion distortion, cf. Fig. 1.28. Fig. 1.28. WebCut a hole about 1 inch (2.5 cm) square in a card. Tape a piece of aluminum foil over the hole in the card and use the pin to punch a small hole in the center of the foil. (You can make a good pinhole by placing the foil on a thick piece of cardboard and rotating the pin.) If your light bulb already has writing on it, you're all set.

WebPinhole Optics and Resolution Most optical devices rely on refraction or reflection to provide an image on a screen or film plane. A pinhole camera is a device which uses neither lenses nor mirrors to produce its image, but rather only a small circular aperture, or ‘pinhole’. This apparent lack of what one might consider an imaging optic does WebThe setup—including the spherical mirror, light source, light block, and video camera—requires careful alignment in a space that is at least 7 meters long and 2 meters wide. The effect can only be seen through the video camera, …

A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called 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. The size of the images depends on the distance between the object and the pi… http://mesh.brown.edu/desktop3dscan/ch2-math.html
