His sheet polarizers found applications ranging from the identification of chemical compounds to adjustable sunglasses. Land founded the Polaroid Corporation in 1937 to commercialize his new technology. His inexpensive polarizer made it possible to reliably and practically filter light so only wavelengths with a particular orientation would pass through. Land created “polarizers” by growing small crystals and embedding them in plastic sheets, altering the light passing through depending on its orientation in relation to the rows of crystals. Modern 3D goggles work because one eye receives light waves vibrating along the horizontal plane while the other eye receives the light vibrating along the vertical plane.īefore Land, researchers built components to control polarization from rock crystals, which were assigned almost magical names and properties, though they merely decreased the velocity or amplitude of light waves traveling at specific orientations. Given the right material for the light waves to pass through, the light waves may be rotated into another plane, slowed down or blocked. Light is considered polarized if the amplitude varies in a consistent manner perpendicular to the direction the wave is traveling.Ī polarizing filter can block all the light waves that don’t match its orientation. Most light sources produce a mixture of waves with all different physical properties, such as wavelength and amplitude of vibration.

You can think of light as waves propagating from a source. Controlling light’s propertiesĮdwin Land’s first optics breakthrough came as a young man, when he figured out a convenient and affordable method to control one of the fundamental properties of light: polarization. Land Medal, awarded by the Optical Society of America and the Society for Imaging Science and Technology, my own work relies on Land’s technological innovations that made modern imaging possible. I’m a vision scientist who has touched many of the fields in which Land made great advances, through my own work on new imaging methods, image processing techniques and human color vision. He also worked on theoretical problems, drawing on a deep understanding of both chemistry and physics.

The camera aboard the U-2 spy plane, as featured in the movie Bridge of Spies, was a Land product, as were even some aspects of the plane’s mechanics. The technology used to show a 3D movie and the goggles we wear in the theater were made possible by Land and his colleagues. But this is just one of a host of technological breakthroughs Land invented and commercialized, most of which centered around light and how it interacts with materials. His Polaroid camera was first released commercially in 1948 at retail locations and prices aimed at the postwar middle class. Land is probably best known for the “instant photo” – or the spiritual progenitor of today’s ubiquitous selfie. 21, 1947, at a meeting of the Optical Society of America. The film exposure and processing hardware are contained within the camera there’s no muss or fuss for the photographer who just points and shoots and then watches the image materialize on the photo once it spools out of the camera. Land demonstrated his new technology publicly for the first time on Feb. Three years later, after plenty of scientific development, Land and his Polaroid Corporation realized the miracle of nearly instant imaging. The original Polaroid camera freed users from needing to trek to a darkroom to develop their images. But in 1943 when 3-year-old Jennifer Land asked to see the family vacation photo that her dad had just taken, the technology didn’t exist.

Today, thanks to smartphones and other digital cameras, we can see snapshots immediately, whether we want to or not. It probably happens every minute of the day: A little girl demands to see the photo her parent has just taken of her.
