Replication optics for a holographic 3D display system

Replication optics for a holographic 3D display system

Conference on current developments in lens design and optical engineering IV

作者： Wood, A Smith, M Stanley, M Thales Opt Ltd St Asaph LL17 0LL Denbigh Wales

ISBN: (纸本)0819450464

The display of 3D images containing all the depth cues required by the human vision system can be achieved using a reconfigurable Computer Generated Hologram (CGH) with high pixel count. A technique which has been developed to produce CGH's with the required number of pixels, and at video refresh rates, is known as Active Tiling((TM)) (AT). At the heart of an AT system is a set of replication optics which produces multiple images of a Spatial Light Modulator (SLM) onto the CGH. The design of two alternative optical systems for generating a 5x5 tiled array of de-magnified images of a single object is discussed. Results are presented from a 4-channel AT system which has recently been built and demonstrated.

Conference on current developments in lens design and optical engineering IV

作者： Bäumer, S Shulepova, L Willemse, J Renkema, K Philips High Tech Plast NL-5503 LP Veldhoven Netherlands

ISBN: (纸本)0819450464

Injection molded optics are frequently applied in many high volume applications. Bar code scanners.. CD / DVD systems, CMOS cameras are a few examples. In all of these applications cost effective and fast design cycles are essential. At Philips High Tech Plastics we developed a design system that touches on all different aspects of the system design. Starting with traditional lens design (sequential ray tracing) and tolerancing we transport the initial design into mechanical solid modeling. During mechanical modeling, tolerances, injection molding design rules and integration of mechanical features, reference marks, etc. are incorporated as well. Here the full advantage of injection molding can be utilized. After the opto - mechanical modeling the system is ported back to non - sequential ray tracing for ghost - and stray light analysis. Finally extended tolerancing is performed in order to come to a robust high volume product. If necessary all or several steps in this design process are repeated in order to arrive at the final design. As an additional requirement the metrology possibilities for the design are checked at an early stage. This integral system approach to optical design, including optical modeling (sequential and non-sequential) combined with mechanical solid modeling is presented using some recent examples.

Conference on current developments in lens design and optical engineering IV

作者： Malone, RM Frogget, BC Kaufman, MI Watts, PW Bell, PM Celester, JR Bechtel Nevada Los Alamos NM 87544 USA

ISBN: (纸本)0819450464

The National Ignition Facility (NIF) requested an optical diagnostic for measuring shock velocities, shock breakout times, and shock emission of objects with sizes of I to 10 mm. For the polar port of the target chamber, an 8-inch triplet lens collects light at f/3 inside a 30-foot-diameter vacuum chamber and uses an optical relay to send the image into two interferometers located at a distance of 160 feet. Light propagates through a VISAR (Velocity Interferometry System for Any Reflector) interferometer employing a Mach-Zehnder configuration. After exiting the interferometers the images are recorded, both by streak cameras and CCD gated imagers. Discrete magnification changes are accomplished by swapping out optical elements. Large dove prisms are used to rotate the image to align a selected region of the object with the slits of the streak cameras. Unique mounting structures are required to remotely control the alignment of the optical axis. Finite Element Analysis (FEA) was performed on all mounting structures. The first 8-inch triplet can be no closer than 500 mm from the target chamber center and is protected by a blast window that has to be replaced after every event. The first several lens groups have to be fused silica for radiation resistance. A frequency-doubled Nd:YAG laser, operating at 659.5 nm, is used to illuminate the moving object. The VISAR laser wavelength had to be different than the first, second, and third harmonics of the NIF drive lasers.

Conference on current developments in lens design and optical engineering IV

作者： Thibault, S Lacoursière, J Doucet, M Wang, M Reecht, J INO St Foy PQ G1P 4S4 Canada

ISBN: (纸本)0819450464

We present three designs and tolerances of wide-field imagers (30x30 arc-minutes or larger) for astronomical surveying. Two infrared cameras (CPAPIR and PANORAMix II) were designed for the 0.8-2.4 mum band and a third one (WIRCAM) for the visible and near-infrared band extending from 410 nm to 950 nm. The cameras are installed on the telescopes of the Canada-France-Hawaii (Hawaii, USA) and Mont Megantic Observatories (Quebec, Canada). The three cameras are compact, use only spherical refractive components and have an internal pupil accessible for insertion of filtering components. A Lyot stop must be used in the infrared camera for background rejection. For PANORAMix II, a set of filters is used at the internal pupil. Correction of the large off-axis aberrations generated by the telescopes, wide spectral coverage, material choices, cryogenic temperature and alignment were the main design challenges. Also, tolerancing was particularly critical for the infrared cameras because they are cryogenically cooled, thus forbidding adjustment of internal components. The cameras theoretical performances are presented in terms of point-spread function, encircled energy and distortion.

Structured design method for automotive lamp reflectors

Structured design method for automotive lamp reflectors

Conference on current developments in lens design and optical engineering IV

作者： Sikkens, M Nuyens, P Philips Ctr Ind Technol Ind Opt Grp NL-5600 MD Eindhoven Netherlands

ISBN: (纸本)0819450464

The design of critical automotive lamp reflectors, e.g. headlamps and fog lamps, is dominated by trial-and-error methods and rules-of-thumb, supported by optical ray-tracing tools like ASAP etc. In many cases these reflectors are designed by aiming small sections to construct the required illumination distribution, which is a time-consuming task and in which case it is very difficult to maintain a continuous reflector surface. The design method presented here is a more structured approach in which the total available front surface is divided in a few relatively large sections, each section designated to produce a certain part of the required light distribution. An optimizing algorithm is used to optimize the separate polynomial reflector sections in combination with a specific burner. In the final step, the separate sections are put together to form a more-or-less continuous reflector surface. Some iteration afterwards is still required because the intersection lines of the polynomial surfaces will generally change the original section boundaries. The design of a front fog reflector lamp is used as a carrier to demonstrate the approach. Three reflector sections are used to design a high-efficiency fog lamp. The light distribution has an excellent horizontal cut-off that basically meets the SAE requirements.

current developments in lens design and optical engineering IV

作者： Bruce Jr., C.F. Jet Propulsion Laboratory California Institute of Technology Pasadena CA 91109

This paper provides an overview of the Tropospheric Emission Spectrometer (TES) and its mission, as a part of NASA's Earth Observing System (EOS). The design of the re-imaging system and its detectors and the test set-up used to characterize the field of view response will be presented. Measured system optical response profiles will be presented for each of the four infrared spectral bands (3.5-5.3, 5.1-9.1, 8.3-12.2 and 11.1 - 15.4 μ) supported by TES. Specific emphasis will be placed upon the comparison of these measured optical response functions with the results of an analytic model of the response. The model includes a simple yet accurate representation of the detector response function, which includes the photo-generated electron's diffusion length.

We have developed a new method other than traditional technique based on ray tracing and optimization algorithm to design arbitrary aspherics. Analytic definition of the aspheric surfaces is done away with and numerical solution of nonlinear difference equations called Aspheric Intrinsic Equations (AIE) is implemented instead. Simulation results compared with traditional optical design software are presented, which prove that this new method is more effective and reliable in designing aspheric surfaces.
