Photon Correlation Spectroscopy and Velocimetry


Book Description

Following the first Capri School on Photon Correlation Spectroscopy held in July 1973 and published earlier in this series (Series B: Physics v.3) a second Capri NATO Advanced Study Institute on this topic was held at the Hotei Luna from 26 July to 6 August 1976. This volume contains the invited lecture courses and seminars and some of the contributed seminars presented at this Institute. Much had happened in the field in the intervening three years and it was the intention of the Organising Committee to build on the previous courses • without detailed repetition of fundamentals. and to extend the coverage widely over the use of photon-correla tion methods for the temporal or spectral analysis of fluctuating light sources. In particular, the rapid expansion of these methods for the measurement of macroscopic motion by Laser Doppler Veloci metry was given special emphasis as is indicated in the title. The members of the Organizing Committee were: E R Pike, RSRE, Malvern, UK } _ Co-directors H Z Cummins, CCNY, New York, USA M Bertolotti, University of Rome, Italy - Local Organiser P Pusey, RSRE, Malvern, UK - Treasurer V DeGiorgio, CISE, Milan, Italy P Lallemand, ENS, Paris, France Pierre de Gennes assisted the Committee during the planning of the Institute but was unfortunately prevented at the last minute from attending.










Photon Correlation Techniques in Fluid Mechanics


Book Description

Photon correlation is a kind of spectroscopy designed to identify optical frequency shifts and line-broadening effects in the range of many MHz down to a few Hz. The optical intensity is measured in terms of single photon detection events which result in current pulses at the output of photomulti plier tubes. This signal is processed in real time in a special-purpose paral lel processor known as a correlator. The resulting photon correlation func tion, a function in the time domain, contains the desired spectral informa tion, which may be extracted by a suitable algorithm. Due to the non-intrusive nature and the sound theoretical basis of photon correlation, the phenomena under study are not disturbed, and the parameters in question can be precisely evaluated. For these reasons photon correlation has become a valuable and in many instances indispensable technique in two distinct fields. One of these is velocimetry in fluid flow. This includes hydro- and aerodynamic processes in liquids, gases, or flames where the velo city field may be stationary, time periodic, or turbulent, and may range from micrometers per second for motion inside biological cells to one kilometer per second for supersonic flow. The other major field is stochastic particle propagation due to Brownian motion.

Interfacial Transport Phenomena


Book Description

This is an extensively revised second edition of "Interfacial Transport Phenomena", a unique presentation of transport phenomena or continuum mechanics focused on momentum, energy, and mass transfer at interfaces. It discusses transport phenomena at common lines or three-phase lines of contact. The emphasis is upon achieving an in-depth understanding based upon first principles. It includes exercises and answers, and can serve as a graduate level textbook.




Looking To The 21st Century: Proceedings Of The 1st International Conference On Frontiers Of Physics


Book Description

This volume is the record of the first meeting of Chinese physicists from Mainland China, Taiwan, Hong Kong, as well as the rest of the world. The participants included all four Nobel laureates of Chinese origin, the Presidents of Academia on both shores of the Taiwan Straits, academicians, OCPA and APS prize recipients, and leading researchers in many areas of physics. Included in the volume are the plenary talks of T D Lee, C N Yang, reports from all four major research facilities, as well as most of the invited papers and abstracts from the poster sessions.
