The task of this research project is to define the extent of applicability of such 3D self-manufacture approach to the production of optical fastenings. The resulting lack of equipment, to be used for demonstration of simple experiments, which would be both competitive in performance and cheap to produce, led to the decision to research opportunities for self-manufacturing.

An original method to enable the exact solution for the noncemented two-lens objective by means of any number of simultaneous non-linear equations is described. The method is limited to spherical surfaces without decentrations. Separations and refractive indices of glasses are fixed. Ail curvatures of surfaces are indirectly determined in the final stage. The typical meridional aperture aberrations deal with aplanatic and achromatic conditions. Essence of the method relies on formulation functions which contain trigonometric expressions and are nested up to certain depth. The method uses the advanced professional mathematical software which is indispensable for serving the non-linear system of equations. Numerical examples confirm the helpfulness of the method.

New catadioptric objectives have been developed with large bandwidths in the DUV, high numerical apertures (NAs), and small size. This can be achieved using a single glass material. designs are specifically optimized for loose alignment tolerances and ease of manufacturability. Applications include broad band DUV imaging and high resolution immersion imaging for industrial microscopy and life sciences.

A miniaturized instrument for systematic planetary mineralogy is presented, and the optical design of the component parts is discussed. The instrument combines the following capabilities: wide field color imaging, confocal imaging at two different resolution/range levels, reflectance spectroscopy in the 400-2500 nm region with a resolution of 10 nm, and Raman spectroscopy over 4000 cm(-1) with an average resolution of 3.3 cm(-1). The instrument can also serve as an expandable platform for adding fluorescence spectroscopy, or for examining samples from a distance of several meters while using the same spectrometer.

This paper describes the Rubicon(tm) actuator, discusses its test data and derives from the data the actuator's accuracy function based upon the observed accuracy of long and short stroke motion commands. The accuracy is described in terms of the rms positioning error (in nanometers) for moves of a given size, regardless of position in the stroke.

A spaceborne telescope has been designed and analyzed for a 2-micron solid state coherent lidar system operating on a satellite. The optical system consists of a large off-axis reflective telescope, a large-aperture diffractive scanner, an image derotator and a lag angle compensator. Due to the orbiting motion of the satellite and scanning, the boresight of the telescope shifts during the round trip travel time of the laser pulses to the target. In a coherent lidar system utilizing optical heterodyne detection, the relative alignment of the received signal with respect to the local oscillator beam is particularly critical. Two compensators have been designed to correct the boresight errors as well as the wavefront errors caused by beam wandering due to the boresight changes. Several design approaches for the compensators have been investigated. The optical and optomechanical design issues for such a system are discussed. The results of optical performance, modeling, and tolerance analysis for the telescope are also presented.

A binocular extends the range of human vision. Binoculars enable the user to see objects at greater distances or, alternatively, to see greater detail in distant objects. In failing light, binocul are used to detect objects that the naked eye cannot detect. Binoculars also extend the range of stereo vision of the user; this application is primarily of interest in military fire control.

Reliable fabrication and assembly of high-quality electro-optical imaging systems is a critical challenge facing electro-optical imaging system manufacturers. optical compensation is one standard approach for minimizing the effects of errors introduced during the manufacture and construction of the optical subsystems. We describe how digital image processing should be considered as a form of compensation when evaluating a complete imaging system. We describe a novel method for digital-optical compensation which jointly adjusts both optical parameters and image processing parameters to maximize end-to-end imaging performance. We verify the superiority of this joint compensation strategy over the traditional sequential compensation through several example imaging systems.

5TH CONF ON current developments IN optical design AND optical engineering

High-resolution space-based imaging applications are limited by the difficulty of placing large monolithic mirrors in space and by technology limitations on the diameter achievable in monolithic mirrors. Multiple-mirror imaging systems can overcome these limitations but require precise alignment-error sensing and correcting schemes to maintain all elements in phase. When a wide field of view is desired, the complexity increases substantially since significant error terms will be a function of field angle. Approaches which can reduce the complexity of the error sensing/correcting schemes are thus of great interest. By sampling selected spatial frequencies, representative of both the individual subapertures and errors between subapertures, measurement of all error terms except absolute piston can be achieved. A technique which places a nonredundant mask in the compacted pupil plane of a phased-array imager and senses the selected spatial-frequency magnitude and phase in the focal plane has been analyzed. This technique can reduce complexity in the local error-sensing system while accounting for all tilt, geometry, magnification, and relative piston errors.
