Radiometric Temperature Measurements Summary:

This book describes the theory of radiation thermometry, both at a primary level and for a variety of applications, such as in the materials processing industries and remote sensing. This book is written for those who will apply radiation thermometry in industrial practice; use radiation thermometers for scientific research; the radiation thermometry specialist in a national measurement institute; developers of radiation thermometers who are working to innovate products for instrument manufacturers, and developers of non-contact thermometry methods to address challenging thermometry problems. The authors of each chapter were chosen from a group of international scientists who are experts in the field and specialists on the subject matter covered in the chapter. A large number of references are included at the end of each chapter as a resource for those seeking a deeper or more detailed understanding. This book is more than a practice guide, readers will gain in-depth knowledge in: (1) the proper selection of the type of thermometer; (2) the best practice in using the radiation thermometers; (3) awareness of the error sources and subsequent appropriate procedure to reduce the overall uncertainty; and (4) understanding of the calibration chain and its current limitations. Covers all fundamental aspects of the radiometric measurements Discusses practical applications with details on the instrumentation, calibration, and error sources Authors are from leading national labs working in R&D of temperature measurements

Broadband UV VIS and IR Radiometric Photometric Color and Temperature Measurements Summary:

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.

Locoregional High Frequency Hyperthermia and Temperature Measurement Summary:

The present challenge in the treatment of tumors is to reduce the number of patients that still die as a result of primary tumors. Today, the percentage of such deaths remains high at 30%, even when all the common therapeutic methods, namely surgery, radiotherapy, and chemotherapy, are applied. In order to reduce this percentage, new types of radiation sources with a higher linear energy transfer have been intro duced, such as neutrons and pions. Fractionation patterns have been modified and radiosensitizers have been applied to in crease biological efficiency. Studies of the combined application of chemotherapy and radiotherapy have been made to find the best therapeutic effect. In the early 1970s biological findings confirmed the effect of hyperthermia on tumor cells. The first clinical studies on hyper thermia treatment demonstrated that it resulted in better local tumor control. Further application of this treatment modality showed that hyperthermia should be used in addition to radio therapy and chemotherapy. Despite these encouraging results, hyperthermia has not been introduced into common clinical use, due primarily to technical problems. There are a number of methods of transferring heat into tumors; however, with regard to physical conditions, an op timum method has not yet been found. One of the reasons is that up to now we have had no reliable method of obtaining thermal mapping of all parts of the human body. Such measurements are required not only for dosimetric purposes but also for the regula tion of a hyperthermic system.

Absolute Temperature Measurement at Microwave Frequencies Summary:

The measurement of absolute temperature under field operating conditions is usually achieved at the expense of tedious calibration using carefully controlled cryogenic devices. In this report, a technique is described by means of which such measurements can be made using only conventional laboratory hardware. Two Dicke-type radiometers have been developed and constructed which embody this technique. The measurement system that has been developed establishes the rf zero of the radiometer and determines the absolute temperature while operating in a rf-balanced condition. A simplified laboratory calibration of the device and the effect of gain stability on measurement accuracy, while observing temperatures near absolute zero, are discussed. Field measurements of sky temperature using standard gain horns and a 28-foot parabolic antenna were conducted at frequencies of 8 and 15 gHz. The experimental results of the program are compared with theoretical predictions of sky temperature for various atmospheric opacities.
