current developments in optical design and engineering VI conference

作者： Chen, YS Li, DH Institute of Physics Chinese Academy of Sciences Beijing 100080 China

ISBN: (纸本)0819422517

In this paper, combining refractive and diffractive effects, a new kind of infrared lenses with wavelength 10.6 mu m was designed and produced for CO2 laser material processing. This refractive-diffractive lens (RDL) converts a CO2 laser beam into the rectangular shape with light intensity distribution in the concave shape at x-direction. A method which employs input aperture division and geometrical transformation technique for obtaining a better initial phase distribution of the iteration is presented. The experimental results show that the desired shape of the output light beam was obtained with a high efficiency in energy utilization.

An afocal optical system designed to be attached to a conical optical beam deflector is discussed The conical beam deflector generates a collimated optical beam that rotates along a cone-shaped trajectory in space. This output beam is then fed to the afocal attachment, a telescope, designed to tailor the beam characteristics to suit a particular application. For many applications, the afocal attachment functions as a beam expander and modifies three characteristics of the input beam. First, it expands the input beam diameter to an acceptable level. Then, it inevitably reduces the apex cone angle of the beam due to the inherent property of a telescope. Third, the stationary plane, the plane where the apex of the cone resides, is magnified and transferred to the conjugate image plane.

A fast (F/1.55) and wide-angle refractive camera objective has been developed to work with a large-size CCD on the focal plane of the spectrograph of Mont Megantique telescope for large spectral coverage from UV to VIS and up to NIR. The novel camera objective has been designed and optimized with three different glass combinations in order to have higher throughputs for large spectral coverage, especially in UV region. The tolerance analysis of the camera objective is given in the paper. The final opto-mechanical design of the objective is discussed with the consideration of the manufacturing tolerance in the optical and mechanical parts, as given in this paper. The used components have been minimized to reduce the light inherent lost. The optical testing results displayed the good optical performance of the camera with the required resolution for the whole FOV, as predicted by the optical simulation and computation. The broadband AR coating, enhanced on UV region, have been used on each surface of the lenses in the optical system.

In Free Gyroscopic Stabilized Seekers, the Primary Minor has the multiple functions of a magnetic rotor, the primary rotating mass and the primary reflector for the optical train. The introduction of rare-earth magnetic alloys to this class of seeker has provided increased flexibility in materials selection, opto-mechanical design and cost of manufacture. Along with superior magnetic properties, the rare-earth alloy Neodymium-Iron-Boron (NdFeB) comes with the undesirable properties of anisotropic CTE, high susceptibility to corrosion and manufacturing challenges. This paper discusses the opto-mechanical design, structural and optical modeling and analysis of a primary mirror assembly utilizing an NdFeB insert with centrifugal, linear acceleration and thermal loading as well as the optical test results, qualification testing of long-term figure stability and validation of the mechanical/magnetic/optical design model.

The paper presents the mathematical technique for calculation of the diffraction depth of focus of an optical system of a widefield microscope. The proposed technique applies the Rayleigh criterion based on evaluation of the wave aberration appeared due to defocus in a high aperture optical system. The maximal value of a linear approximation of the defocus wave aberration is used to define the depth of focus. It is proven that in optical systems with numerical aperture higher than 0.5 have the diffraction depth of focus 25 - 40% smaller than the widely known formula defines. This fact is important for implementation of autofocus and digital focus extension algorithms. The non-sophisticated formula for calculation of the depth of focus is proposed. The results of experimental measurements of the depth of focus are presented and discussed.

Freeform technology is one of the most promising solutions for enhancing the capability of aberration correction and improving performance of optical systems. Aiming to demonstrate the freedom and flexibility of optical system design, several challenging design examples using freeform surface are presented, including two wide-angle camera lenses adopting even and odd pedal polynomial formulations for symmetric optical surface description, and an anamorphic cinema lens employing non-rotationally symmetric surfaces for capturing a wider aspect ratio and offering a 1.33 x squeeze factor on a 4:3 sensor size. Methods and constraints for designing and optimizing the optical systems are discussed. The optical performances of these design examples are analyzed and the results verify the practicability and effectiveness of the proposed formulations and design strategies in the field of freeform imaging optical design.

In this study, a low glare and high-efficient tunnel lighting design which consists of a cluster light-emitting diode and a free-form lens is presented. Most of the energy emitted from the proposed luminaire is transmitted onto the surface of the road in front of drivers, and the probability that the energy is emitted directly into drivers' eyes is low. Compared with traditional fluorescent lamps, the proposed luminaire, of which the optical utilization factor, optical efficiency, and uniformity are, respectively, 44%, 92.5%, and 0.72, performs favorably in traffic safety, energy saving, and glare reduction.

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.

A refractive astigmatic lens is employed to generate a focus error signal (FES) for servo control in general optical pickup. In this paper, a diffractive optical element (DOE) is designed to implement optical functions of astigmatic focusing for a MEMS-based miniature optical pickup at 650nm wavelength. We present a diffractive astigmatic lens with its internal zones and external zones quantized into four, two phase levels, respectively based on fabrication consideration. The optical simulation based on scalar diffraction theory shows the efficiency of this quantized lens for astigmatic focusing and a comparison of the FES in the optical pickup system has been plotted.
