The structural influence coefficients for an imaging optical system map the decenter and tilt motions of the system elements to changes in the direction and orientation of the line-of-sight and image. A methodology is presented to calculate the structural influence coefficients for the lenses of long-focus (near-infinity) imaging optical systems. Single-lens systems are considered first, with the method then extended to handle multiple elements. Use of an arbitrary structural reference frame is discussed, along with an algorithmic, recursive approach to numerical calculation of the structural influence coefficients. A complete derivation is presented at each step, and an overview of the geometric optical principles involved is provided for reference. The method described allows ready calculation of influence coefficients without tedious ray-trace perturbations or dedicated optical analysis software. This paper is a companion to a previous paper by the authors, in which the structural influence coefficients for plane-mirror systems are derived. The influence coefficient method of both papers is unique in its use of line-of-sight reference frames as an optical kinematic tool to track pointing direction and image orientation.

An ion beam milling system, used for precision optical fabrication, was modified to easily allow deposition of thin films onto the same optics within a single vacuum operation. A series of coating experiments was performed to assess this approach to integrated ion milling and optical coating. Attempts were made to maximize the deposition rates while maintaining a narrow distribution of coating material to provide the optimum total process time. A series of shaped sputter targets was found to maintain high deposition rates similar to those of a flat target but without having the desired effect of narrowing the material distribution. Apertured shields produced narrow material distributions but at the expense of significantly lowering the deposition rates. Despite these limitations, analysis shows that thin optical films can be produced in a reasonable time by this approach.

Abnormal dispersion is found in a large number of optical liquids. These liquids are quite useful in the design of apochromatic lens systems because they are inexpensive and are readily available compared to the expensive abnormal dispersion glasses and crystals more commonly used. Further, there is no practical upper limit on the size of a liquid optical element. However, because the use of these materials as optical elements is quite new, the long term stability of their optical properties after exposure to various environmental conditions must be determined. In this paper, we report on a series of tests performed to determine the optical stability of several abnormal dispersion liquids. The liquids were subjected to: (1) high intensity ultraviolet radiation, (2) high temperatures, and (3) long term exposure to air. Measurements of both optical transmission and refractive index were performed before and after each exposure. The tests were performed on four abnormal dispersion liquids that have been found to be quite useful in the design of apochromatic lenses. The results indicate that long term exposure to either intense ultraviolet radiation or air, produced only negligible changes in the index of refraction. Changes in optical transmission were observed, but they were largely confined to the ultraviolet spectral region. Prolonged exposure to temperatures of 60 degree(s)C did not produce any measurable change in the optical properties. The measurements were performed at the Vavilov State optical Institute, St. Petersburg, Russia, in collaboration with Lockheed Palo Alto Research Laboratory, Palo Alto, California.

An important step in the fabrication of an optical component involves the imparting of a precise contour on the optic, which can be expensive and time consuming. Ion beam figuring is the imparting of a contour on an optical component by removing material through the impingement of a broad beam of accelerated neutral particles, and provides a highly deterministic method for the final precision figuring (or correcting) of optical components with advantages over conventional methods. The high predictability allows the possibility of single step figuring, resulting in significant time and cost savings. And unlike grinding, polishing and lapping, ion figuring is non-contacting and so avoids several problems including: edge roll off effects, tool wear, and loading of the work piece. It has previously been demonstrated that ion figuring is effective for the correcting of large optical components. These implementations typically use the process for final figure correction on meter class optical components. The work discussed here is the development of the Precision Ion Machining System (PIMS) at NASA's Marshall Space Flight Center, designed for the processing of smaller (less than 10 cm diameter) optics. Initial experiments using a Kaufman type ion source to figure 8 cm diameter fused silica and silicon carbide samples were successful. Experiments involved correcting flat samples and imparting spherical and aspherical contours.

design of mechanical features such as spacers, retainers and/or cell shoulders used to locate and constrain lens components within a mount entails application of geometric relationships that depend upon the types of glass-to-metal interfaces to be provided. This paper describes the pertinent geometry of the most common surface-contact interface types ("sharp corner", spherical, tangential and toroidal) and gives equations for locating key features of the mechanical parts relative to the associated lens vertices. Examples illustrate the use of these equations to dimension mechanical features in typical lens/mount configurations. © 1994 SPIE. All rights reserved.

Prior publications dealing with techniques for estimating axial contact stresses in lenses mechanically clamped axially near their rims have assumed the lenses to be single elements. In this paper, we expand the theory to include multiple-element lenses such as cemented doublets and optomechanical designs with spacers or equivalent cell features between separated lenses. Examples are given to illustrate the use of these new analytical techniques. © 1994 SPIE. All rights reserved.

The ultimate goal of optical instrumentation is to achieve the desired image quality in a given application. This requires a homogenous blend of optical and mechanical design, fabrication, system integration and testing tasks. The space optical systems generally require near theoretical performances in hostile environments within size, weight and cost constraints. Hence a careful tolerance analysis plays a crucial role in these systems. For space optics, the importance of image quality, cost and related tolerance analysis cannot be over-emphasized. In this paper, we have tried to address the challenge of achieving an optimum image quality through a cost effective tolerance analysis. Two different space optical systems are considered: the UV imager for the International Solar Terrestrial Physics (ISTP) Mission and an afocal telescope for the Advanced Polarized IR Imaging Sensor (APIRIS). These systems are described along with their required performances and designs, with an explanation of the tolerance study conducted. The effect of tolerances on the image quality and cost are investigated. © 1994 SPIE. All rights reserved.

Liquids have not found widespread application in optical design for a number of reasons, one of which is the fact that index of refraction data for liquids is available for only very few compounds, and the data that do exist are only in the visible spectral region. In this paper we report on the results of our joint project for measuring the refractive index of liquids in the infrared (IR) spectral region. A number of liquids have transmission passbands that extend well into the IR, to wavelengths of 10 μm and beyond. Many of these liquids also have abnormal dispersion and are suitable for low-cost apochromatic lens designs in the infrared. Using these materials, design options that significantly reduce the cost and weight of IR imaging systems become available. These measurements have been made at the Vavilov State optical Institute, Saint Petersburg, Russia, in collaboration with the Lockheed Palo Alto Research Laboratory. © 1994 SPIE.

A two-mirror asymmetrical system has been designed to reshape a laser beam into an elliptic uniform beam profile for use in a new superbroadband color center laser system. The surface points of the two mirrors are obtained by solving a second order partial differential equation of the Monge-Ampere type which is based on conservation of energy and the law of reflection. The technique is illustrated by presenting the design of a two-mirror system which converts a circular Gaussian beam into an elliptic beam with a uniform profile. Such a reshaper system is planned for use in the development of superbroadband or control generation spectrum color center lasers, which have a significant potential for optical communications, signal multiplexing, and information coding as well as laser spectroscopy, photochemistry, medicine, color microscopy, and holography. © 1994 SPIE.

Genetic algorithms, developed by J. H. Holland, are randomized search algorithms which mimic the mechanics of natural selection and natural genetics. In this work a genetic algorithm was applied to optimization of sophisticated thin-film systems. It was found to be an efficient tool rapidly converging to the target as defined by the merit function. The algorithm is introduced, discussed, and illustrated for two applications: a polarization-preserving coating of a penta-roof prism for a long-grange optical sight and a phase light splitter--beam divider/combiner for bi-directional fringe-counting interferometers.
