conference on Advanced optics for Defense Applications - UV through LWIR II

Recently, optical materials have been developed by Schott and NRL to improve material selection in the SWIR, MWIR, and LWIR wavelength regions. In addition, new multiband detectors are reaching maturity, leading to a natural push for common aperture lens systems. Detectors that can span the SWIR/MWIR, MWIR/LWIR or SWIR/MWIR/LWIR wavelengths regions will require complex optical systems to effectively utilize their full potential. designing common aperture wide-band systems that are both achromatized and passively athermal, especially while maintaining SWAP-c (size, weight, power and cost), poses significant challenges. Through use of the updated gamma v-v diagram, which provides guidance on material combinations that both achromatize and athermalize, part of that challenge is reduced. This updated gamma v-v diagram uses instantaneous Abbe number and peak wavelength. The instantaneous Abbe number is a function of wavelength and is the scaled reciprocal of the instantaneous dispersion. The instantaneous Abbe number is defined at the peak wavelength, which occurs when the second derivative of the index of refraction goes to zero. Three examples will be presented using this updated athermal/achromatic glass map to demonstrate its effectiveness. These design examples will include a SWIR/MWIR design, a MWIR/LWIR design and, a SWIR/MWIR/LWIR design.

Development of laser systems requires optical components with high performance, and a high-precision double-beam laser photometer was designed and established to measure the optical performance at 1064nm. Double beam design and lock-in technique was applied to decrease the impact of light energy instability and electric noise. Pairs of samples were placed symmetrically to eliminate beam displacement, and laser scattering imaging technique was applied to determine the influence of surface defect on the optical performance. Based on the above techniques, transmittance and reflection of pairs of optics were obtained, and the measurement precision was improved to 0.06%. Different types of optical loss, such as total loss, volume loss, residual reflection and surface scattering loss, were obtained from the transmittance and reflection measurement of samples with different thickness. Comparison of optical performance of the test points with and without surface defects, the influence of surface defects on optical performance was determined. The optical performance of Nd-glass at 1064nm were measured as an example. Different types of optical loss and the influence of surface defects on the optical loss was determined.

Students at the school level from grade 7 to 12 are taught various concepts of geometrical optics but with little hands-on activities. Light propagation through different media, image formation using lenses and mirrors under different conditions and application of basic principles to characterization of lenses, mirrors and other instruments has been a subject which although fascinates students but due to lack of suitable demonstrating setups, students find difficulty in understanding these concepts and hence unable to appreciate the importance of such concepts in various useful scientific apparatus, day to day life, instruments and devices. Therefore, students tend to cram various concepts related to geometrical optics instead of understanding them. As part of the extension activity in the University Grants Commission major research project "Investigating science hands-on to promote innovation and research at undergraduate level" and University of Delhi at Acharya Narendra Dev College spie student chapter, students working under this optics outreach programme have demonstrated various experiments on geometrical optics using a five beam laser ray box and various optical components like different types of mirrors, lenses, prisms, optical fibers etc. The various hands-on activities includes demonstrations on laws of reflection, image formation using plane, concave and convex mirrors, mirror formula, total internal reflection, light propagation in an optical fiber, laws of refraction, image formation using concave and convex lenses and combination of these lenses, lens formula, light propagation through prisms, dispersion in prism, defects in eye-Myopia and hypermetropia. Subjects have been evaluated through pre and post tests in order to measure the improvement in their level of understanding.

conference on Dimensional optical Metrology and Inspection for Practical Applications III

作者： Harding, Kevin GE Global Research (United States)

3D structured light systems based upon phase shifting analysis are well described in the literature. One of the challenges to obtaining high quality data is the noise often associated with the mechanism to shift the projected pattern accurately. The common methods of realizing a phase shift is to either mechanically move a grating pattern that is then projected to the part, or to move the pattern electronically in a programmable projector such as an LCD, LCOS or other projector. These projectors, often made for office use, are limited by the pixel resolution and the stability of the projectors. Mechanical shifts can be very precise, but require time and the maintenance of a mechanical movement. Other systems using projected interference patterns that use piezo shifters are faster and more reliable, but then can suffer from coherent speckle noise. This paper will discuss a unique optical design using a lens made telecentric in image space and an electro-optical image shifting approach that provides very fast image shifts in a very repeatable and controlled manner.

ISBN: (纸本)0819452920

We present design-for-manufacturing and yield (DfM/DfY) results on SRAM of the 65-nm node by connecting knowledge of device performance with that of lithographic optical enhancement techniques. Of special interest was the lithographic quality of line-ends and gates, the former being the most critical for yield and manufacturing control. Scalability towards lower technology nodes was also part of the choice. All these considerations led to the choice of alternating-aperture phase-shift lithography as optimal reticle-enhancement technique. Predictions from simulations were verified on the wafer for SRAM cells of multiple geometry contexts, misalignment was included, and the illuminator was optimized.

IRIS is a diffraction-limited imaging spectrograph designed for first light of the Thirty Meter Telescope (TMT). It is fed Multi-Conjugate Adaptive optics (MCAO)-corrected light from the Narrow-Field Infrared Adaptive optics System (NFIRAOS). IRIS, however, is responsible for sensing the low order modes: tip, tilt, focus, and plate scale modes to which the NFIRAOS Laser Guide Star (LGS) Wavefront Sensors (WFSs) are blind. During the IRIS final design, we developed a noise-equivalent angle budget that included the optical throughput of the telescope, NFIRAOS and OIWFS, the detector pixel size, quantum efficiency, readnoise and excess shot noise, diffraction including optical aberrations, and sky and thermal backgrounds. The noise equivalent angle was calculated for the near-infrared star brightness corresponding to 50% sky coverage at the North Galactic Pole for an exposure time required to meet the overall TMT wavefront error budget. We present the trade studies, performance budgets and simulation results which drove the final design of the optics, mechanics and detectors of the IRIS OIWFS system.

High-resolution vehicle headlamps represent a future-oriented technology that can be used to increase traffic safety and driving comfort. As a further development to the current Matrix Beam headlamps, LED-based pixel light systems enable ideal lighting functions (e.g. projection of navigation information onto the road) to be activated in any given driving scenario. Moreover, compared to other light-modulating elements such as DMDs and LCDs, instantaneous LED on-off toggling provides a decisive advantage in efficiency. To generate highly individualized light distributions for automotive applications, a number of approaches using an LED array may be pursued. One approach is to vary the LED density in the array so as to output the desired light distribution. Another notable approach makes use of an equidistant arrangement of the individual LEDs together with distortion optics to formulate the desired light distribution. The optical system adjusts the light distribution in a manner that improves resolution and increases luminous intensity of the desired area. An efficient setup for pixel generation calls for one lens per LED. Taking into consideration the limited space requirements of the system, this implies that the luminous flux, efficiency and resolution image parameters are primarily controlled by the lens dimensions. In this paper a concept for an equidistant LED array arrangement utilizing distortion optics is presented. The paper is divided into two parts. The first part discusses the influence of lens geometry on the system efficiency whereas the second part investigates the correlation between resolution and luminous flux based on the lens dimensions.

conference on Modeling, systems Engineering, and Project Management for Astronomy VI

Aero-thermal simulations are an integral part of the design process for the Thirty Meter Telescope (TMT). These simulations utilize computational Solid-Fluid Dynamics (CSFD) to estimate wind jitter and blur, dome and mirror seeing, telescope pointing error due to thermal drift, and to predict thermal effects on performance of components such as the primary mirror segments. design guidance obtained from these simulations is provided to the Telescope, Enclosure, Facilities and Adaptive optics groups. computational advances allow for model enhancements and inclusion of phenomena not previously resolved, such as transient effects on wind loading and thermal seeing due to vent operation while observing or long exposure effects, with potentially different flow patterns corresponding to the beginning and end of observation. Accurate knowledge of the Observatory aero-thermal environment will result in developing reliable look-up tables for effective open loop correction of key active optics system elements, and cost efficient operation of the Observatory.

The MCAO Assisted Visible Imager and Spectrograph (MAVIS) is a new visible instrument for ESO Very Large Telescope (VLT). Its Adaptive optics Module (AOM) must provide extreme adaptive optics correction level at low galactic latitude and high sky coverage at the galactic pole on the FoV of 30arcsec of its 4k x 4k optical imager and on its monolithic Integral Field Unit, thanks to 3 deformable mirrors (DM), 8 Laser Guide Stars (LGS), up to 3 Natural Guide Stars (NGS) and 11 Wave Front Sensors (WFS). A careful performance estimation is required to drive the design of this module and to assess the fulfillment of the system and subsystems requirements. Here we present the work done on this topic during the last year: we updated the system parameters to account for the phase B design and for more realistic conditions, and we produced a set of results from analytical and end-to-end simulations that should give a as complete as possible view on the performance of the system.
