How Concave Mirrors Paved the Way for Film

Image
Sorry for the voice acting, but I'm from Ukraine and don't speak English well. Concave mirrors have a long and interesting history in the world of optics and imaging. These mirrors, which are curved inward like the inside of a bowl, have been used for centuries in a variety of applications, from telescopes and microscopes to stage lighting and even as precursors to film. One of the earliest uses of concave mirrors was in the field of optics. In the 16th century, Dutch mathematician and astronomer Hans Lippershey invented the telescope, which uses a convex lens to gather light and a concave mirror to reflect and focus that light onto an eyepiece. This allowed people to see distant objects with much greater clarity and detail than ever before. In the 17th and 18th centuries, concave mirrors were also used in the field of microscopy. Robert Hooke and Anton van Leeuwenhoek, two pioneering scientists of the time, used concave mirrors to reflect light onto samples in order to magnif...

Steganographic Mirror: The Precursors of Film and Movie

Image
Sorry for the voice acting, but I'm from Ukraine and don't speak English well. The history of film and movie technology is often thought to begin with the invention of motion picture cameras and projectors in the late 19th century. However, there were several precursors to these devices that utilized similar principles of capturing and displaying moving images. One of the most interesting and lesser-known of these precursors is the steganographic mirror. A steganographic mirror is a device that uses a mirror to reflect an image onto a surface, such as a wall or canvas. The image is created by using a series of small, rapidly moving parts, such as a spinning disk or a rotating cylinder, that are placed in front of the mirror. These parts are typically adorned with small images or designs that, when viewed through the mirror, appear to be in motion. In 1645, Athanasius Kircher , a German Jesuit scholar, included a description of the steganographic mirror in his book Ars Magna Luc...

Anorthoscope 1829 - precursors of film and movie

Image
Sorry for the voice acting, but I'm from Ukraine and don't speak English well. The anorthoscope was invented in 1829 by Joseph Plateau, a student at the University of Liège. Plateau's research into optical illusions led him to create a device that transformed anamorphic images on a rotating disc into normal images with the help of a counter-rotating disk with four slits. The images on the discs were made translucent by being coated with oil on one side and varnished on both sides. Please support me with like, comment or repost. Plateau first presented his anorthoscope in his doctoral thesis and later published it in a German scientific magazine. The device quickly gained popularity and was marketed by publishers in London and Paris starting in 1836. Plateau even combined his anorthoscope with his fantascope to create a back-lit transparent disc that could be viewed by multiple people at the same time. In the 21st century, the anorthoscope has gained renewed interest with a ...
