In optics, an aperture is a hole or an opening through which light travels.
A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.
In photography, a color filter array (CFA), or color filter mosaic (CFM), is a mosaic of tiny color filters placed over the pixel sensors of an image sensor to capture color information.
Colorimetry is "the science and technology used to quantify and describe physically the human color perception." It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
In electronics, crosstalk is any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel.
In optics, defocus is the aberration in which an image is simply out of focus.
A digital single-lens reflex camera (also called digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.
An entocentric lens is a compound lens which has its entrance or exit pupil inside the lens.
In an optical system, the entrance pupil is the optical image of the physical aperture stop, as 'seen' through the front of the lens system.
The euro (sign: €; code: EUR) is the official currency of the European Union.
In optics, the exit pupil is a virtual aperture in an optical system.
The f-number of an optical system (such as a camera lens) is the ratio of the system's focal length to the diameter of the entrance pupil.
The focal length of an optical system is a measure of how strongly the system converges or diverges light.
In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.
The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development.
An image sensor or imaging sensor is a sensor that detects and conveys the information that constitutes an image.
In radiometry, irradiance is the radiant flux (power) received by a surface per unit area.
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.
A light-emitting diode (LED) is a two-lead semiconductor light source.
Machine vision (MV) is the technology and methods used to provide imaging-based automatic inspection and analysis for such applications as automatic inspection, process control, and robot guidance, usually in industry.
Magnification is the process of enlarging the appearance, not physical size, of something.
Metrology is the science of measurement.
Optical resolution describes the ability of an imaging system to resolve detail in the object that is being imaged.
Orthographic projection (sometimes orthogonal projection), is a means of representing three-dimensional objects in two dimensions.
Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals.
Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate.
Radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.
In optics a ray is an idealized model of light, obtained by choosing a line that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow.
A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc.
A three-CCD (3CCD) camera is a camera whose imaging system uses three separate charge-coupled devices (CCDs), each one receiving filtered red, green, or blue color ranges.
The United States dollar (sign: $; code: USD; also abbreviated US$ and referred to as the dollar, U.S. dollar, or American dollar) is the official currency of the United States and its insular territories per the United States Constitution since 1792.
In photography and optics, vignetting (vignette) is a reduction of an image's brightness or saturation toward the periphery compared to the image center.
