Optical radiation measurement terminology and definition
This specification is to amend JJF 1032-1992 "Optical Radiation Measurement Terms and Definitions" (Trial) specifications,
Expanded. It covers the basic concepts, quantities and units related to the profession, measurement benchmarks and standards, calibration and testing
The total number of laws, instruments and reference materials, and engineering measurement terms reached 557. And subdivided according to its internal contact.
General terms, irradiance, luminosity, spectral luminosity, chromaticity, laser irradiance, fiber characterization, radiation detectors and
Nine chapters on optical components are available for inspection.
1 general terminology
1.1 [electromagnetic] radiation [electromagnetic] radiation
(1) the emission or propagation of energy in the form of electromagnetic waves associated with photons;
(2) This electromagnetic wave or photon itself.
1.2 wavelength wavelength
The distance between two adjacent points in the same phase in the direction of periodic wave propagation. Its symbol is λ and the unit is m.
Note.
1 The wavelength in the medium is equal to the wavelength in the vacuum divided by the refractive index of the medium. Unless otherwise stated, the wavelength value usually refers to air.
Value. Standard air (in spectroscopy, t = 15 ° C, p = 101325 Pa) refractive index value for visible radiation is 1.00027~
Between 1.00029.
2 In optical radiation measurement, the commonly used wavelength units are nm or μm.
1.3 wave number wavenumber
The reciprocal of the wavelength. Its sign is σ and its unit is m-1.
Note. The wave number unit commonly used in spectroscopy is cm-1.
1.4 speed of light velocityoflight
Usually refers to the speed at which light (ie electromagnetic waves) travel in a vacuum, symbol c, in m/s. It does not follow the frequency
Or a change in wavelength, the value of which is defined as.
c=299792458m/s
The velocity v of light propagating in the medium is less than c and varies with the refractive index n of the medium or the frequency of the light wave.
v=
1.5 frequency frequency
The speed of light divided by the quotient of the wavelength, ie ν=
The symbol is ν and the unit is Hz. Electromagnetic radiation propagates in any medium
When it is, its frequency remains the same.
1.6 optical radiation opticalradiation
The wavelength is between the X-ray transition zone (≈1 nm) and the transition to the radio wave (≈1 mm)
radiation. Referred to as optical radiation.
1.7 visible radiation visibleradiation
