Cheap-and-cheerful pinhead camera doesn’t need lens
A Cornell-developed camera that fits on the head of a pin, contains no lenses or moving parts and costs pennies to make could revolutionize an array of scientific fields from surgery to robotics. Writing about the device in the journal Optics Letters, the researchers say it is only 100th of a millimeter thick and one-half […]
