Broadband UV VIS and IR Radiometric Photometric Color and Temperature Measurements

Book Description :

In most field applications, broadband measurements are used where the spectral product of the source distribution and the meter’s spectral responsivity is measured. This book discusses detector-based radiometric, photometric, color, radiation-temperature, digital imaging-system, and LED measurements. It also shows that, while in photometry, the meter’s standard response covers only the visible, broadband measurements in the UV and IR require different standards. To avoid large errors when using a traditional detector- or source-standard, where the differences in the source distributions and in the meter’s responsivities produce large errors, the signal measurement procedure itself must be standardized. To satisfy the steps of the procedure, selected or properly designed meters should be used. This book is a guide to performing uniform broadband measurements with low uncertainty.

Book Description :

A 4-color spectroscope using the wavelengths 0.546, 0.577, 0.623, and 0.750 microns was used to determine the surface temperatures of electrically exploded wires and aluminum projectiles of velocity 4,500 m/sec. Several values of initial capacitor energy, pressure, and ambient atmosphere were used with the exploded wires. The projectiles were observed in a normal atmosphere at 710 mm Hg. The temperatures observed for exploded wires for an initial capacitor energy of 0.8 joule in air at 710 mm Hg were: 3825! 25 K for aluminum, 3100! 75 K for copper, and 3700! 25 K for tungsten. For an aluminum projectile in air at 710 mm Hg at a velocity of 4,500 m/sec, the temperature observed was 3250! 50 K. The spectral distribution in all cases was observed to be black body and could be fitted by the Wien radiation law. Calibration was achieved using a tungsten ribbon lamp. Blackbody radiation data from the Planck radiation law are also given using the new value for the second radiation constant, C2 = 14,388 microns K for temperatures from 2000 to 4000 K and wavelengths from 0.500 to 0.800 microns.

Book Description :

The recently developed optical radiation detectors need well-designed radiometers to perform improved radiometric, photometric, colorimetric, and radiation-temperature measurements. They can produce higher performance than traditionally used blackbody sources and lamps in wider application areas. This book presents research-based material in this field that has been implemented, realized, tested, verified, and evaluated. It can be used as a reference source for students, practicing scientists, engineers, technicians, instrument manufacturers and measurement/calibration people to learn, design, build, select, and use new generation radiometers. The book describes a number of design issues and applications to implement the correct input geometry for detectors to measure radiometric (power, irradiance and radiance) quantities, and DC, AC, and pulsed electrical output signals.

Book Description :

A 9 channel, integrated radiometer for recording multi-frequency sky brightness temperatures from which atmospheric integrated water, and water vapor and temperature profiles may be estimated has been designed, constructed and field-tested. The radiometer includes 3 water-dependent (22.25, 23.9, 31.45 GHz) and 6 oxygen-dependent (50.5, 53.0, 53.6, 54.89, 58.64, 61.03 GHz) frequencies. The radiometer includes 4 Dicke-type subsystems of 2, 1, 3 and 3 multiplexed frequencies each. Control and signal processing functions are accomplished using 8 digital signal processors, 2 per subsystem, which are in turn controlled by an 80286-equipped host computer. The basic radiometer package, exclusive of the host computer and multichannel signal processing chassis, is about 1/2 x 1/2 x 1 m and is designed for airborne and shipboard (antenna pedestal) mounting as well as ground-based overland operation. All system, antenna pointing control, and signal processing functions are handled through the host computer. The radiometer may be readily used in combination with wind profilers, ceilometer, sodar and other measurement systems as are useful for improving the precision and spatial resolution of inverted water and temperature profiles.

Thermal Return Reflection Methods for Resolving Emissivity and Temperatures in Radiometric Measurements

Book Description :

A radiometric method for resolving the emissivity, E, and temperature, T, in thermal emission measurements is presented. Thermal radiation from a viewed source is split by a beamsplitter between a radiometer and a mirror aligned to return a part of the thermal radiation back to the source. The ratio of the thermal signal with and without a return reflection provides a measurement of the emissivity without need of any other probing sources. The analytical expressions that establish this relationship are derived taking into account waveguide/optic losses and sources between the radiometer and viewed sample. The method is then applied to thermal measurements of several refractory materials at temperatures up to 1150 ʻC. A 137 GHz radiometer is used to measure the emissivity and temperature of an alumina brick, an Inconel 690 plate, and two grades of silicon carbide. Reasonable temperature agreement is achieved with an independent thermocouple measurement. However, when the emissivity approaches zero, as in the case of the Inconel plate, radiometric temperature determinations are inaccurate, though an emissivity near zero is correctly measured. This method is expected to be of considerable value to non-contact thermal analysis applications of materials.

Book Description :

This book, the first of a two-volume set, focuses on the basic physical principles of blackbody radiometry and describes artificial sources of blackbody radiation, widely used as sources of optical radiation, whose energy characteristics can be calculated on the base of fundamental physical laws. Following a review of radiometric quantities, radiation laws, and radiative heat transfer, it introduces the basic principles of blackbody radiators design, details of their practical implementation, and methods of measuring their defining characteristics, as well as metrological aspects of blackbody-based measurements. Chapters are dedicated to the effective emissivity concept, methods of increasing effective emissivities, their measurement and modeling using the Monte Carlo method, techniques of blackbody radiators heating, cooling, isothermalization, and measuring their temperature. An extensive and comprehensive reference source, this book is of considerable value to students, researchers, and engineers involved in any aspect of blackbody radiometry.

Effect of Radiometric Errors on Accuracy of Temperature profile Measurement by Spectral Scanning Using Absorption emission Pyrometry

Book Description :

The spectral-scanning method may be used to determine the temperature profile of a jet- or rocket-engine exhaust stream by measurements of gas radiation and transmittance, at two or more wavelengths. A single, fixed line of sight is used, using immobile radiators outside of the gas stream, and there is no interference with the flow. At least two sets of measurements are made, each set consisting of the conventional three radiometric measurements of absorption-emission pyrometry, but each set is taken over a different spectral interval that gives different weight to the radiation from a different portion of the optical path. Thereby, discrimination is obtained with respect to location along the path. A given radiometric error causes an error in computed temperatures. The ratio between temperature error and radiometric error depends on profile shape, path length, temperature level, and strength of line absorption, and the absorption coefficient and its temperature dependency. These influence the choice of wavelengths, for any given gas. Conditions for minimum temperature error are derived. Numerical results are presented for a two-wavelength measurement on a family of profiles that may be expected in a practical case of hydrogen-oxygen combustion. Under favorable conditions, the fractional error in temperature approximates the fractional error in radiant-flux measurement.
