41. The FinePix 40i, like other high-end Fuji digital cameras, has a special octagonal pixels in its light sensitive charge-coupled device . 42. Most digital cameras used a " charge coupled device " of pixel-sized receptors to gather light coming through the lens. 43. It is situated at 1300 m altitude and houses an optical telescope with a charge-coupled device used for asteroid surveys. 44. The new camera, however, is the first from Nikon to use a CMOS image sensor rather than a charge-coupled device . 45. In the 1990s development of charge coupled device ( CCD ) imagers to read barcodes was pioneered by Welch Allyn. 46. Arrays of detectors, such as charge coupled devices ( CCD ) or photodiode arrays ( PDA ) can also be used. 47. This field of light is monitored by charge-coupled devices ( CCDs ) similar to the ones used in consumer digital cameras. 48. The three charge-coupled devices , or CCDs, gave it the ability to produce broadcast-quality images that are unattainable with a single-CCD camera. 49. Through the use of a charge-coupled device ( CCD ), the tip can easily be positioned directly over the laser spot. 50. All Phase One digital backs launched prior to the IQ250 have sensors based on the CCD ( Charge-coupled device ) technology.
