Praxinoscope

Hye!

Are you still with me? I hope you do. 😊

Now, I would like to start on Praxinoscope. Do you know what is it? Well, first of all, the praxinoscope was invented in 1877 by the Frenchman Charles Reynaud. It was the first device to overcome the picture distortion caused by viewing through moving slots. The image produced is more brilliant than with any previous devices. The praxinoscope was advance that it quickly  replaced the zoetrope in popularity. 

The Praxinoscope was a typical optical toy from the 19th century. It consists of a cylinder and a strip of paper showing twelve frames for animation. As the cylinder rotates, stationary mirrors in the centre reveal a ‘single image’ in motion. The Praxinoscope was invented in 1876 by Charles-Émile Reynaud (1844-1918), a Paris science teacher, who marked all his examples ‘E.R.’. The toy became a great commercial success and won recognition at the great exhibitions of the period. 

Moreover, it was a theory of images being painted on long strips of celluloid that were displayed from the inside like being inserted in slits around the drum which was spun around. Though the Praxinoscope improved upon the Zoetrope theory with the slits on the Praxinoscope becoming inner circles of mirrors within the optional illusion device. A band of pictures is placed inside a shallow outer cylinder, so that each picture is reflected by the inner set of mirrors.  The number of mirrors is equal to the number of pictures, and the images of the pictures are viewed in the mirrors.  When the outer cylinder rotates, the quick succession of reflected pictures gives the illusion of a moving picture.
