A forerunner of the modern camera, this instrument had a focusable lens that produced a sharp image on the enclosure opposite the aperture but had no photosensitive material to record it.
camera reduction
The use of the photographic process to produce precision copies of an original image that are many times smaller in size. One of its many applications is in microcircuitry.
camera shutter
An apparatus, designed for use with a camera, that is used to rapidly open the path from lens to film, to maintain the opening throughout exposure and to close the opening in rapid succession. The...

The electron beam tube of a television camera that converts an optical image into a pattern of electrostatic charges and then scans the pattern to produce a corresponding electronic signal for...
camera tube target
The storage surface of an electron beam tube that is scanned by an electron beam to generate an output-signal current corresponding to the charge-density pattern stored.
aerial camera
Camera designed for the imaging of the earth's surface in order to obtain high quality aerial images
astronomical camera
A camera designed to record astronomical objects (e.g., stars, planets, nebulae, galaxies) and their spectra.
Baker-Nunn camera
A wide-field camera based on the classic Schmidt optical system used to photograph Earth-orbiting satellites.
ballistic camera
A camera that uses multiple exposures to record the trajectory of an ordnance from a ground-level position.

A CCD camera, or charge-coupled device camera, is a type of digital camera that utilizes a CCD image sensor to capture and record images. CCD cameras are widely used in various applications,...
CID camera
CID, or charge injection device, camera refers to a type of imaging device that utilizes a specific kind of solid-state image sensor technology. CID cameras are capable of capturing images in a...
cine camera
A camera capable of making successive exposures on a continuous film driven by accurately spaced sprocket holes (a motion picture camera).
CMOS camera
A CMOS camera refers to an imaging device that employs a complementary metal-oxide-semiconductor (CMOS) image sensor to capture digital images. CMOS cameras have become ubiquitous due to their low...
copying camera
A camera mounted on an optical bench with an easel to hold the material to be copied. Magnification can be varied over a wide range by sliding the camera and easel.
cryogenically cooled LWIR camera
A cryogenically cooled long-wave infrared (LWIR) camera is a specialized thermal imaging device designed to detect infrared radiation in the long-wave infrared spectrum, typically ranging from 8 to...
digital camera
A digital camera is a device that captures and records still images or video in digital format. Unlike traditional film cameras, which use photographic film to capture and store images, digital...
drum camera
A type of streak camera that uses film wrapped around a drum, which moves at a constant speed to record the changing shape of a short-lived event, such as a lightning flash.
electron diffraction camera
A special evacuated camera equipped with means for holding a specimen and bombarding it with a sharply focused beam of electrons. A cylindrical film is placed around the specimen to record the...
electron multiplication charge-coupled device camera
An EMCCD (electron-multiplying charge-coupled device) camera is a type of scientific camera specifically designed for low-light imaging applications that require high sensitivity and fast readout...
electrostatic tape camera
A camera that records its images electrostatically on plastic tape; used in situations where radiation would have an adverse effect on regular photographic film.
fingerprint camera
A fixed-focus camera designed to record the ink impression of fingerprints that have been impressed on a card or form for record purposes.
flow camera
An automatic camera that can record reduced images of documents at a rate of up to 30,000 documents per hour by having the film and documents move synchronously in opposite directions.
fluorographic camera
A camera with a very high aperture lens or mirror system for photographing x-ray fluorescent screen images, mainly to save the cost of large pieces of 11 x 14-in. film. The film may be 4 x 5-in. cut...
frame camera
A high-speed cine camera that produces discrete frames of a continuous event as opposed to the flow photographic record of a streak camera.
gamma camera
A camera used in scintillation recording to make a visible record of the distribution and relative concentration of radioactive tracer elements in a sample that is undergoing scanning.
gun camera
A camera accurately aligned to a weapons system to provide a photographic record of system performance.
gyroscopic camera mount
A mount that uses a floating suspension and a motor-driven gyroscope to keep a motion picture or still camera at a set angle even though the camera is mounted in a place that subjects it to heavy...
high-sensitivity camera
A high-sensitivity camera is a type of camera designed to perform well in low light conditions, capturing clear and detailed images with minimal noise. These cameras typically feature advanced sensor...
high-speed motion camera
A high-speed motion camera, also known as a high-speed camera or slow-motion camera, is a specialized imaging device designed to capture fast-moving events or phenomena at extremely high frame rates....
high-speed movie camera
A camera designed to record at rates exceeding 50 fps. For frame rates up to about 500 fps, an ordinary pull-down mechanism can be used. From 500 to 1000 fps, the film must be moved continuously, the...
high-speed still camera
A still camera with a shutter capable of opening for a time as short as a fraction of a microsecond. An electronically operated Kerr cell often is employed.
holocamera
A camera system used to form a high-precision hologram of the subject on a photographic plate. It contains a high-power pulsed laser as the illuminating source.
