Pinhole cameras have been used on space vehicles since the late 1950s. Nuclear physicists have used pinholes to photograph high-energy rays. WebThe first lensless camera is a pinhole camera that consists of an image sensor with a pinhole at a predetermined distance in front of the image sensor. The pinhole serves to block most of the light that would otherwise enter the camera—but allows only those light rays that pass through the pinhole to reach the image sensor.
