Conference on current developments in lens design and optical engineering IX

Automated computer-aided procedure for component selection, optical design, and optimization was developed and used to produce prototype ocular optics of a head-mounted display for biomedical imaging, with the field of view and resolution approaching those of normal human vision. The new display has the potential to dramatically increase the amount and fidelity of real-time visual information presented to the user. The selected approach was based on a tiled configuration and "optically stitched" virtual image, resulting in seamless imagery generated by multiple micro-displays. Several optical configurations were studied in the design stage, to arrive at the optimal optical layout. The automated procedure provided for extensive search of the best candidate stock components out of thousands of candidate lenses offered by different vendors. At each iteration, the candidate lens was "digitally inserted" in the optical layout, its position was optimized, and the achieved merit function characterizing the quality of the stitched image was stored, along with the design prescription. A few best designs were then closely evaluated in a traditional "manual" procedure. The design effort was followed by experimental demonstration and tests of a limited prototype optical system.

We have designed a fisheye lens with a field of view of 190 degrees and F# of 2.8 The diameter of the circular image plane is designed to fit within the width of the image sensor plane, so that a 190 degrees horizontal field of view can be obtained. It is composed of 8 spherical lens elements and the overall length is 35mm from the first lens surface to the image sensor plane. This fisheye lens operates simultaneously in the visible and the near infrared wavelength regions.

Aspheric and diffractive surfaces in infrared materials are traditionally fabricated by single point diamond turning, which is a high-cost, low-throughput process, not suitable for low-cost, high-volume applications. Precision molding of chalcogenide glasses is a novel process we developed to allow the efficient fabrication of quality infrared optics in large volumes. In this paper we present the advantages and particularities of designing thermal imaging lenses for high-volume applications using precision molded chalcogenide glasses. As an example, we present a compact 19 mm F/1.1 infrared lens design for a 320 x 240 uncooled detector array operating from 8 to 14 microns. The excellent image quality and transmission of tested prototypes prove that precision molding of chalcogenide glasses is an ideal optical fabrication technology for the high-volume production of infrared optics.

Recent times have seen the production of normal and micro liquid lenses with variable focal length. These have been specially made with transparent elastic materials and liquid medium between them, or with a dielectric liquid medium inside the cavity. Change in the volume of the liquid medium, in the first case, or the application of an electric field as in the second, produced a change in the optical parameters of the lens. The present study offers the opto-mechanical design, manufacture and characterization of a solid elastic lens made of Polydimethylsiloxane (PDMS). To do so, we have prepared a mechanical support frame to hold all of the components of the lens and also allow for the application of radial stress on its periphery. In order to ensure a well-finished lens surface a high quality optical glass mold has also been constructed. Finally, we will present an analysis of the properties of this type of lens when it undergoes variations of radial stress. The experimental results are presented.

Refractive elements are commonly used on Cassegrain-form telescopes to correct off-axis aberrations and both widen and flatten the field. Early correctors used two lenses with spherical surfaces, but their performance was somewhat limited. More recent correctors have three or four lenses with some including at least one aspheric surface. These systems produce high resolution images over relatively wide fields but often require the corrector and mirrors to be optimized together. Here we present a new corrector design using five spherical lenses. This approach produces high image quality with low distortion over wide fields and has sufficient degrees of freedom to allow corrector to be optimized independent of the mirrors if necessary.

The diffractive optical element (DOE) is always modeled as an ideal pure diffractive clement which neglects the refractive dispersion of the clement's material. In this paper, a new model of the diffractive optical element is proposed, in which the effect of the refractive dispersion of the DOE's material is considered. The new model is explained and compared with standard diffraction-order expansion with the help of a hybrid system example. The analytical results show that the new model has an important meaning for the exact analysis of the hybrid refractive-diffractive optical system.

An optical system application required a high speed laser scanning subsystem that produced high quality extended images focused at 32 discrete separated positions along a line, rather than continuously varying positions along the line as in more familiar scanning systems. This paper describes the optical design trades and selection of a grating-based scan element that produces this unusual type of scan, and the optical design methods that corrected aberrations produced by the scan element. A variety of different grating-based scan element designs were explored, in a flat disk geometry, but these produced excessive aberrations, both in the absolute level and in the magnitude of variation with scan. A ring-shaped scan element geometry was identified, which greatly minimized the scan-varying aberrations and brought them to near acceptable levels. Additional cylindrical corrector elements were added near the ring scan element to reduce the astigmatism of the ring substrate, and cylindrical lenslets were placed near the focus to provide further independent correction of astigmatism in each scan position. The resulting design achieved diffraction limited wavefront quality across the scan range.

Using raytracing method (ZEMAX program), the reduction of SA of the whole human eye may be reduced via the combined effects of asphericity (Q) and the ratio of the front and back surface of an IOL. The overall SA for best image quality may be defined by Q* when the image position off axis is reduced to that of the paraxial. Our calculations show the following general features: (1) For a give Q value, the influence on the SA is proportional to the surface power;(2) for minimal whole eye SA, negative Q is needed in IOL;(3) for a given IOL power, the Q* is smaller when the front surface has a smaller power. All above features derived from numerical raytracing method are consistent with analytic formulas.

Foveated imaging addresses the need for compact wide-angle imagers capable of high-resolution and compressed data transmission. The principle behind foveated imaging is to cover a wide field-of-view (FOv) with a relatively simple and compact low-resolution lens, and use a liquid crystal spatial light modulator (SLM) to correct wavefront aberrations at any selected field point. The SLM correction provides a high-resolution fovea that can be actively moved anywhere within the FOv. While most research has focused so far mainly on SLM performance, the general trend being to increase SLM resolution and modulation depth, the actual lens design and system optimization aspects were often neglected. In this paper, we propose a wide-angle lens design intended for foveated imaging applications, and discuss typical tradeoffs. Taking this design as an example, we present a method to estimate the smallest SLM resolution required to correct the wavefront error effectively, showing that with the appropriate design, this resolution can be reduced up to 10 times compared to current designs. Increasing the SLM resolution beyond this point and increasing the modulation depth above one wavelength is not necessary, and will actually reduce the performance of the imaging system. We also demonstrate the importance of fabrication tolerances, and we propose a method to calibrate the SLM in order to cancel out all additional wavefront aberrations introduced by fabrication and assembly errors.

Conducting high resolution field microscopy with coupled laser spectroscopy that can be used to selectively analyze the surface chemistry of individual pixels in a scene is an enabling capability for next generation robotic and manned spaceflight missions, civil, and military applications. In the laboratory, we use a range of imaging and surface preparation tools that provide us with in-focus images, context imaging for identifying features that we want to investigate at high magnification, and surface-optical coupling that allows us to apply optical spectroscopic analysis techniques for analyzing surface chemistry particularly at high magnifications. The camera, handlens, and microscope probe with scannable laser spectroscopy (CHAMP-SLS) is an imaging/spectroscopy instrument capable of imaging continuously from infinity down to high resolution microscopy (resolution of similar to 1 micron/pixel in a final camera format), the closer CHAMP-SLS is placed to a feature, the higher the resultant magnification. At hand lens to microscopic magnifications, the imaged scene can be selectively interrogated with point spectroscopic techniques such as Raman spectroscopy, microscopic Laser Induced Breakdown Spectroscopy (micro-LIBS), laser ablation mass-spectrometry, Fluorescence spectroscopy, and/or Reflectance spectroscopy. This paper summarizes the optical design, development, and testing of the CHAMP-SLS optics.
