The Impossible Project was renamed Polaroid Originals in September 2017. The original Polaroid Corporation was founded in Cambridge, Massachusetts, by Edwin Land in 1937. Described by "The Boston Globe" as
Polaroid (polarizer) component of the electric field perpendicular to the line of crystals however can cause only small movements in the electrons as they can't move very much from side to side. This means there will be little change in the perpendicular component of the field leading to transmission of the part of the light wave polarized perpendicular to the crystals only, hence allowing the material to be used as a light polarizer. This material, known as "J-sheet", was later replaced by the improved "H-sheet" Polaroid, invented in 1938 by Land. H-sheet is a polyvinyl alcohol (PVA) polymer impregnated with iodine. During
