An object distance range within which fine image can be obtained by focus adjustment is limited since aberrations are caused by change of object distance. We have developed a novel optical design method to suppress variation of coma, astigmatism and field curvature induced by change of object distance. Variation of astigmatism and field curvature can be suppressed by introducing appropriate distortion. Also variation of coma caused by change of object distance can be suppressed by using spherical image surface which pivot is located at the center of exit pupil.

We report a method of engineering constant composition, single crystal, defect free SiGe-on-insulator grown by a rapid melt growth technique using tailored tree-like structures. Branches emanating from the main SiGe strip act as Silicon "reservoirs" to prevent the usual gradation of the alloy composition. This technique enables multiple SiGe strips to be grown using the same single generic Ge deposition step, each with a different composition determined by the structural design. Using this technique, we envisage a silicon photonics platform for on-chip optical communications whereby both modulators and detectors can be fabricated with the same device design and therefore the same simple fabrication steps. This can be realised by exploiting the rapid melt growth SiGe composition engineering detailed in this paper to tune the bandgap of electro-absorption modulators for multi-channel links using wavelength division multiplexing, whilst simultaneously forming pure Ge photodetectors. This technology could open the way for a new multilayer photonic architecture or for extremely low power density, multi-channel on-chip optical communications by integrating the concept with the cascaded photonic crystal architecture demonstrated by Debnath et al. [1].

An artificial method of replacement reflecting surfaces by thin "mirror" lenses gives us the opportunity to create analytical equations as the base for subsequent parametrical synthesis of optical system consisting of two and three reflecting surfaces. In this case optical powers of the components are determined by required image field curvature. The ratios of back focal lens to the distances between the components are considered as parameters. In one particular case we've got a variant of three-mirrors system with acceptable aberration correction when one mirror has a spherical shape. Constructions of three-mirrors optical systems are presented.

A new optical design inclusive of zoom optics and optical engine system is proposed in this paper. Traditionally, there is trade-off between F-number of projection optics and contrast, which seems that super high-contrast image from commercial projector was simply a dream. Some ideas of adaptive optics were announced before for the improvement of high contrast. However, few reach success or cost will be high. Traditionally, there is nothing to do with optics of projector and optical engine of projector if lens meets the specification. In this paper, a new optical design for optics and optical engine is studied with liquid optics arrays. Thanks to advanced optical design and LED light luminance, simulation results show that 50% improvement for image contrast could be made without sacrifice of volumetric size.

Recent advances have made it viable to fabricate optical surfaces that are not rotationally symmetric using a new generation of diamond-turning machines. This new fabrication capability allows for surfaces whose departure from a sphere varies both radially and azimuthally in the aperture to be machined into an optical surface. This new degree of freedom allows for the design of unobscured optical systems that are truly non-symmetric by tilting the optical surfaces themselves. With this new design degree of freedom, the aperture and field of view can be pushed to yield an order of magnitude increase in aerial coverage over current production while maintaining a compact solution. In one particular case, to be presented, a diffraction limited (< lambda/10), long wave infrared (LWIR), F/1.9, 10 degrees full field of view sensor telescope is designed by introducing these non-symmetric surfaces into the optical surface prescription.

The presence of many local minima in the merit function landscape is perhaps the most difficult challenge in lens design. We present a simplified mathematical model that illustrates why the number of local minima increases rapidly with each additional lens added to the imaging system. Comparisons with results obtained with lens design software are made for the design landscape of triplets with variable curvatures, a problem that is nontrivial, but still simple enough to be analyzed in detail. The mathematical model predicts how many types of local minima can exist in the landscape of the global optimization problem and what are, roughly, their curvatures. This model is mathematically quite general and might perhaps be useful as an analogy for understanding other global optimization problems as well, there where the number of local minima increases rapidly when more components of the same kind are added in the model of the problem.

Infrared Focal Plane Array (FPA) sensors are commonly tested using various means of scene generation. At the Arnold engineering Development Center a Direct Write Scene Generator (DWSG) is being developed. The DWSG projects the scene onto the focal plane array by scanning a rake of beams across the sensor. The rake consists of up to 256 synchronous beams generated by passing a single laser beam through an acousto-optic deflector (AOD). A complex radio frequency signal input into the AOD diffracts the laser beam into multiple beams. Each pixel of the focal plane is illuminated by one of the beams in the rake. The Direct Write Scene Generator is being designed to test a focal plane area as large as a 512 X 512 pixel array. Scan optics focus an expanded laser beam to a spot smaller than the focal plane pixel pitch over the entire test area. Several optical configurations and multiple AODs are needed to achieve the test requirements at various wavelengths. Some important considerations in the optical design are spot size, crosstalk, and background radiation.

A dismountable and portable telescope with a large primary mirror (250 mm in diameter) and a numerical aperture of 5.6, is presented. The telescope has a all-spheric catadioptric optical design, consisting of a spherical primary and a group of spherical lenses, where the last surface is aluminized, as a secondary mirror. The group of lenses corrects all the optical aberrations, including the spherical introduced by the primary and the chromatic ones. The telescope has a very compact design, with a physical length of 600mm. This fact, joint with the all-spherical design, make it a ligth portable and easy to align instrument: when dismounted it can be contained in a suitcase sizing 580x440x140 mm and the spherical surface for all the mirrors and lenses makes easy the final alignment of the optical train. We discuss here in detail the optical design and the realized prototype and will show the results, both in terms of theoretical and effective performances.

A fundamental study on evaluating an epoxy-based coating was conducted. The study aimed to determined the performance of the coating on a low carbon steel as a result of chemical contaminations. Coated samples were tested in a local tap water by using the method of real time— holographic interferometry. A mathematical model was used along the obtained experimental data. The model described processes of detecting the early corrosion of the the steel under the coatings by holographic interferometry. Consequently, the holographic interferonxetry technique was found very useful in detecting the early corrrosion processes of the coated steel Also, a relationship between the displacement of the coating ,dueto metal corrosion under the coating, and corrosion current density of the coated steel was established for the epoxy-based coating with and without an addition of sodium chloride to the coating.
