Shock waves passing through a metal sample can produce ejecta particulates at a metal-vacuum interface. Holography records particle size distributions by using a high-power, short-pulse laser to freeze particle motion. The sizes of the ejecta particles are recorded using an in-line Fraunhofer holography technique. Because the holographic plate would be destroyed in an energetic environment, a high-resolution lens has been designed to relay the scattered and unscattered light to a safe environment where the interference fringes are recorded on film. These interference fringes allow particles to be reconstructed within a 12-mm-diameter, 5-mm-thick volume. To achieve resolution down to 0.5 mu m, both a high-resolution optical relay lens and ultraviolet laser (UV) light were implemented. The design and assembly of a nine-element lens that achieves > 2000 lp/mm resolution and operates at f/0.89 will be described. To set up this lens system, a doublet lens is temporarily attached that enables operation with 532-nm laser light and 1100 lp/mm resolution. Thus, the setup and alignment are performed with green light, but the dynamic recording is done with UV light. During setup, the 532-nm beam provides enough focus shift to accommodate the placement of a resolution target outside the ejecta volume;this resolution target does not interfere with the calibrated wires and pegs surrounding the ejecta volume. A television microscope archives images of resolution patterns that prove that the calibration wires, interference filter, holographic plate, and relay lenses are in their correct positions. Part of this lens is under vacuum, at the point where the laser illumination passes through a focus. Alignment and tolerancing of this high-resolution lens will be presented, and resolution variation through the 5-mm depth of field will be discussed.

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.

Studies on adaptive lenses, which are formed of two transparent elastic surfaces and have a transparent liquid medium between them, have focused mostly on the characterization, analysis and optical performance of the proposed lenses. No attention, however, has been given to the mechanical design that would allow the conception of a user-friendly functional mounting that is adaptable to conventional optical systems. This work, therefore, presents the design and manufacturing processes of the mounting for a 20 mm diameter biconvex adaptive lens. It also presents an analysis of the membranes used as elastic surfaces and the images formation of the proposed lens.

A compact zoom lens design for cell phone is presented. A three groups lens system with five lens element is designed for cell phone camera with 3M pixels and 2.5 similar to 3X optical zoom. The first lens is a negative lens with a concave surface facing the object so that, when used for a long focal length, the rear principle plane is moved forwards to shorten the total length of the lens. A positive lens group composed of three lens elements is arranged at the second lens group. By control the optical power of the second lens group, the distortion can be reduced and also shortens the moving distance of the second lens group while zooming. The fifth lens in the third lens group is a positive lens to control the incident angle entering the photosensitive element. It is used for focusing when the object distance has changed.

This research proposes a newly developed method to high zoom lens for mobile phone use, which the overall length is restricted in mobile phone size acceptable. Generally speaking, the optical design with liquid lens might be more complicated in optimization than traditional optics;not only because aspherical coefficient in liquid lens element is difficult to be defined and measured, but also because efficient optics layout needs more efforts to study in the near future. The paper mainly utilizes liquid lens in order to short total length;two liquid lens elements must be included. Besides consider total length, Lateral aberration also is very important. Lateral aberration will play a significant role in the Modulation Transfer function (MTF), so, the optical design will be able to arise very big, and that the many kinds of chromatics aberration with two groups of liquid lens. Using Digital Signal Processing technology principal factor why this also is.

We propose a novel method to correct the spherical and coma aberration using a hybrid element (refractive-diffractive). The refractive surface is used to correct the coma, we obtain this condition curving the second principal plane and centred it on the axial point image. The diffractive element is used to correct the spherical aberration using an exact ray trace and the diffractive coefficients as variables. The optimization routine is no required. This method can be used for any conjugates position.

Some all-spherical designs are presented that are variations of the positive-negative-positive triplet with the stop at the front. Examples include a compact wide angle (60° field of view) near-telecentric lens, as well as super-achromatic, telecentric lenses for the visible to infrared (450-1000nm or 450-2300 nm) and mid-wave and thermal infrared. This design form, loosely thought of as a boosted version of the rear landscape lens, has provided a useful optimization starting point for a variety of designs with different requirements.

Practical guide to saddle-point construction in lens design

Saddle-point construction (SPC) is a new method to insert lenses into an existing design. With SPC, by inserting and extracting, lenses new system shapes can be obtained very rapidly, and we believe that, if added to the optical designer's arsenal, this new tool can significantly increase design productivity in certain situations. Despite the fact that the theory behind SPC contains mathematical concepts that are still unfamiliar to many optical designers, the practical implementation of the method is actually very easy and the method can be fully integrated with all other traditional design tools. In this work we will illustrate the use of SPC with examples that are very simple and illustrate the essence of the method. The method can be used essentially in the same way even for very complex systems with a large number of variables, in situations where other methods for obtaining new system shapes do not work so well.

The traditional approach to optical system engineering separates the scene, optics, and detector as static entities, optimizing the design to meet subsystem specifications of aperture, field size, encircled energy, read noise, dynamic range, and other electro-optical properties. The Scene-Based Sensor Model (SBSM) represents a different approach by simulating the scene, optics and detector as a cohesive model using commercially available optical ray-tracing software. The objects are modeled as temporally changing entities, with characteristics including reflectance, absorbance, fluorescence, and scattering. Likewise, the detectors are modeled with their properties of temporal noise, spatial non-uniformity, nonlinear gain, and offset drift. The end-to-end simulation produces "photons-to-bits" analysis applicable to a variety of optical systems. First results are illustrated with ray tracing simulation of moving fluorescent objects and laser induced breakdown spectroscopy.
