Method of measuring the distance from the pupil, using light reflected from the cornea to the center of the nose.

Corneal abrasion, английский
- A cut or scratch on the cornea.
- A scratch on the cornea, caused by something sharp getting into the eye
Corneal astigmatism, английский
Defect in the curvature of the cornea whereby light rays passing through the cornea produce aberrations and are not focused on the retina.
Corneal bank, английский
A place where eyes of dead donors can be kept ready for use in corneal grafts
Corneal reflex, английский
Irritation of the cornea resulting in reflex closure of the eyelids.
Corneal topography, английский
Mapping or examination of the surface of the cornea.
Corneal transplant, английский
Transplante de córnea
Reflect, английский
- A gradient brush option that makes the gradient repeat in alternating reflections.
- To copy driver binaries, install services, and add registry keys for one or more drivers from a driver package onto a system, without the context of a specific device. a system can be booted from reflected drivers, however full device installation may still be required in order to enable full driver functionality.
Reflect prevention sheet, английский
Reflectance, английский
- The percentage of light that is reflected from an object. spectrophotometers measure an object's reflectance at various intervals along the visible spectrum to determine the object color's spectral curve. see spectral curve, spectral data.
- The ratio of light returned from a surface expressed as a percentage.
- Отражательная способность
- The percentage of light reflected from a component, such as a connector, splice, splitter, or wdm
- The ratio of the reflected flux to the flux incident on a surface. reflectance coefficient, reflectance factor
- Коэффициент отражения, отражательная способность
- Ratio of reflected wave energy to incident wave energy. also known as reflectivity.
Reflectance (or reflection factor), английский
Отражательная способность (или коэффициент отражения). отношение потока лучистой энергии (или света), отражаемой данной поверхностью, к потоку лучистой энергии (или света), падающему на эту поверхность.
Reflectance pattern, английский
A reflectance pattern is an observation whose attributes have been normalized so that their values add up to one. see also: ann, normalization.
Reflectance reflectivity, английский
The ratio of the reflected radiant power to the incident radiant power.
Reflectance. light-reflective glass, английский
Reflectancia, испанский
Reflectancia ., испанский
Reflectancia del nivel de base ., испанский
Reflected, английский
Reflected glare, английский
- Relatively bright light that does not enter the eye directly from the light source, but after it has been deflected by a surface which the direct light has illuminated. it can be either diffuse or specular.
- Glare resulting from specular reflection of high brightness in polished or glossy surfaces in the field of view. also
Reflected light, английский
- Scene illumination multiplied by reflectance. this is the amount of light returned to the camera and determines the quality of picture.
- Various surfaces in a scene reflect between 1% and 95% of the incident light. specular surfaces will reflect it narrowly. diffuse (rough, irregular, or matte) surfaces scatter it. also see: glare and bounce light for further reflections.
Reflected light meter, английский
A meter that reads light reflected from the subject. all in-camera meters are of this type.
