Present methods and equipment for obtaining precision measurement of lengths exceeding 20 or so inches do not provide the required degree of accuracy, repeatability or portability to meet current needs. Inspection methods incorporating the laser interferometer calibration system will provide means of calibrating numerically controlled machines, coordinate measuring machines and long lengths with a high degree of accuracy and confidence.

Download Simulation and Experiment in Laser Metrology Book in PDF, ePub and Kindle
These proceedings document about 45 contributions to the International Symposium on Laser Applications in Precision Measurement held in Balatonfüred/Hungary during June 3–6, 1996. Special emphasis was given to the Combination of Simulation and Experiment in Laser Metrology. International experts provide a survey over a large variety of their latest achievements and developments in this rapidly advancing field. Over the last years, optical measurement techniques like structured illumination, holographic interferometry and tomography were applied more and more in combination with CAE–tools such as CAD and FEM. This combination has found a world of new applications in scientific and industrial branches interested in highly exact but nondestructive and noncontact measurement of technical components. Each of the four sections contains an overview article given by international leading experts. With that the proceedings should be considered to be a state–of–the–art report combining the areas of mathematical modeling of objects, experimental testing under definite stresses, computer–aided evaluation and measuring of objects.

Download Basics of Interferometry Book in PDF, ePub and Kindle
This book is for those who have some knowledge of optics, but little or no previous experience in interferometry. Accordingly, the carefully designed presentation helps readers easily find and assimilate the interferometric techniques they need for precision measurements. Mathematics is held to a minimum, and the topics covered are also summarized in capsule overviews at the beginning and end of each chapter. Each chapter also contains a set of worked problems that give a feel for numbers. The first five chapters present a clear tutorial review of fundamentals. Chapters six and seven discuss the types of lasers and photodetectors used in interferometry. The next eight chapters describe key applications of interferometry: measurements of length, optical testing, studies of refractive index fields, interference microscopy, holographic and speckle interferometry, interferometric sensors, interference spectroscopy, and Fourier-transform spectroscopy. The final chapter offers suggestions on choosing and setting up an interferometer.

Measurement is our fundamental tool for learning about the world around us. It is from observing trends in measurements that we develop the theories that enable us to predict future behaviour, and it is against measurements that we determine the validity of these theories. Increases in the precision of our measurements are fundamental to our understanding. Atom interferometry is a new method for performing precision measurements that uses the matter-wave nature of atoms to perform interferometry experiments analogous to those performed with photons. However, in contrast to optical interferometry, which uses coherent sources of photons, atom interferometry uses thermal atomic sources, in part due to the unavailability of high-flux coherent atomic sources. Although pulsed coherent atomic sources are presently available, continuous sources are not. Creating a truly continuous coherent source for atoms is tricker than for photons. One of the largest challenges is that atom number is conserved. A source of atoms is therefore necessary to produce a truly continuous atom laser. This source must be used to replenish the lasing mode of the atom laser, and the process must operate without significantly disturbing the coherence properties of the lasing mode. It is this replenishment or pumping process that has been investigated theoretically in this thesis. There are only two choices for the reservoir that makes the replenishment (or pumping) process of an atom laser irreversible: the empty modes of the optical field, and the empty modes of the atomic field. Processes of both forms are considered. Using an optical reservoir has the advantage that atoms are not necessarily lost as part of the pumping process, which is necessary when using an atomic reservoir. The efficiency of processes using an optical reservoir can therefore be higher. Using an atomic reservoir, however, has the advantage that it is easier to implement as one can use the standard experimental technique of evaporation which is commonly used in the production of pulsed coherent atomic sources. We show theoretically in this thesis that although it is possible to produce a continuous atom laser using an atomic reservoir, the flux achieved in the geometry considered is insufficient to compete with pulsed coherent atomic sources for precision measurement. The results for the pumping process using an optical reservoir are more promising. Although condensed sources were used as the source for this process, a detailed comparison of the theoretical calculations and experimental results indicate that the detrimental reabsorption processes are suppressed. This suggests that it may be possible to use higher-flux thermal atomic sources to replenish the lasing mode of an atom laser with this pumping process.
