Televisor (Baird's device)

Baird's Televisor was an early experimental television device developed by John Logie Baird in the 1920s. It used a mechanical system with spinning disks featuring tiny holes to scan images, converting visual information into electrical signals, which were then transmitted and reconstructed as moving images on a screen. Although primitive compared to modern TVs, it demonstrated the basic principle of transmitting moving pictures over a distance. The Televisor was a pioneering step in broadcasting technology, laying the groundwork for electronic television systems that followed.
