This invaluable book represents a substantial body of work describing the theory of the optical properties of thin island films and rough surfaces. In both cases the feature sizes are small compared to the wavelength of light. The approach is extremely rigorous and theoretically very thorough. The reflection, transmission and absorption of light are described. Computer programs that provide exact solutions for theoretical properties of thin island films are available, and this makes the book of great practical use. The early chapters present a comprehensive theoretical framework. In this new edition a chapter on reflection from gyrotropic media has been added. Contributions due to the gyrotropic nature of the interfacial layer are discussed.

A superprecision, two-axis, air-static bearing, diamond-turning machine of advanced design has been previously described at this Conference and is now operational. The microtopography and other physical characteristics of surfaces turned by this machine will be examined in detail. Some effects of machining parameters will be briefly discussed. The ability of this machine to turn surfaces with very small slope errors (

Surfaces of mirrors or other optical devices employed in satellite programs will in time become contaminated with thin layers of polymer films. These films originate most likely from outgassing and polymerization by u.v. radiation with condensation on critical optical surfaces. The contaminant films degrade the reflectivity of mirrors and the performance of critical optical surfaces. Atomic oxygen from a high-frequency plasma restores optical surfaces to their original properties by rapid non-contaminating, non-destructive oxidation of the polymer film. (Author).

The motivation of this research stems from the need to detect and identify small particles deposited on a plane surface that is assumed to be otherwise clean. Such detection and identification is, in fact, relevant to all researches in which the cleaness of the surfaces is a fundamental prerequisite and to all the applications whose purpose is the deposition on a surface of particles of a given kind. In the preceding years we addressed our research toward the study of the resonances from particles on account that the resonance spectra are widely known to give useful information both for free particles and for particles on a surface. Nevertheless, our methods were restricted to the case of metallic surfaces because the latter are a good approximation to perfectly reflecting surfaces. In this case, in fact, the image method proved to be very efficient to yield useful information both on the presence and of the shape of the particles of interest. In the last year our interest has been directed toward the properties of particles deposited on non-perfectly reflecting surfaces, i.e. on surfaces that separate two different dielectric media. Of course this new purpose of our research did not stop our study of the shape resonances from particles on metallic surfaces, but our main aim has been toward the formulation of a theory applicable to particles on a surface of general dielectric properties.

It has been demonstrated that copper and other metal surfaces can be diamond single-point machined (DSPM) to a surface quality which will result in nearly intrinsic optical properties. Especially interesting is the observation of the interrelationship of laser-induced melt and slip thresholds for DSPM copper for different surface preparation methods. Particularly important parameters are the machining fluid and the tool geometry. Both of these factors influence the degree of cold work introduced into the surface. In a companion paper at this conference, the nature of the surface damage is correlated with machining conditions. In this paper, the same surfaces are described optically. Significant variation in optical and mechanical properties can be demonstrated. The ability to change the characteristics including laser damage properties of the machined surface can be used in some cases to advantage, to actually tailor the surface to the requirements of a specific application.
