OPTICS
DOMINIQUE-FRANÇOIS-JEAN ARAGO (1786-1853)
In 1811 Arago (l), in alliance w/ Augustin-Jean Fresnel (r), discovered that two beams of light polarized in vertical directions do not interfere, eventually resulting in the development of a transverse theory of light waves.
In 1884 Moëssard obtained a patent for a rotating-lens Panoramic camera. It covered a 170° field of view & was rotated by hand to expose the film.
Pictured is Moëssard’s 'Cylindrographe' illustration from ‘Le Cylindrographe Appareil Panoramique’, 1845, fig. 9, p23. https://t.co/syOmckkeLj
