Book Description
Results are presented from an experimental study of laser beam scintillation along a slant path in the atmospheric planetary boundary layer. The primary objective of this research is to determine the influence on eye safety of atmospheric thermal turbulence in causing locally high intensities of energy in laser beams. This work has resulted in the further development of a general eye-hazard evaluation procedure based on atmospheric effects and laser operating conditions. The present work has also resulted in the development of a simple, 'worst-case' guide to estimate the maximum probability of eye damage.

Book Description
Results of a literature search on the effects of normally occuring atmospheric molecules, aerosols and turbulence on the propagation of low power lasers is presented in a thoroughly cross referenced bibliography. Included are references to theoretical, experimental and modeling studies that could be relevant to developing models (and their required data bases) for the purpose of establishing comprehensive safety standards for laser illumination of the human eye. Two separate computerized literature searches (with extensive manual editing) were utilized, as well as other sources, to locate these references. Current and planned efforts by several key researchers are also described.

Book Description
This thesis presents a computer program designed to analyze the data from a TV camera for investigating laser beam propagation through the atmosphere. It uses aspects of Fourier optical theory to analyze the TV image to measure the effects of atmospheric disturbance and platform stability on the target spot. The understanding and analysis of these effects are increasingly important as lasers and other optical devices experience increased use in military application. (Author).

Book Description
Nearly a decade aga a general review article on the evaluation of optical radia tion hazards was published in Applied Optics (Sliney and Freasier, 1973). This arti cle received many favorable comments but also prompted many inquiries regarding specific optical hazard problems. From this it became evident that a monograph rather than a supplemental and expanded article was needed to fill this literature gap relating to laser and optical radiation hazards. The present work is designed to fill that gap, and is structured to permit either classroom or self-study use. Much of the material in this book was developed in eonnection with short courses on laser safety and radiometry in which we have participated, as weIl as from our previous articles. In particular, the sequenee of chapters is based upon the experiences which we have had in lecturing in courses with different schedules. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or physical scientist, while the review material on basic optical physics is intended more for the physician or life scientist.
