Freeform surfaces provide more degrees of freedom for design of optical systems, and enhance the ability of compensation and correction aberrations. Freeform surfaces are of advantage to balance the unsymmetrical aberrations, especially for the wide-field off-axis optical systems. This paper focus on an off-axis reflective optical system, which focal length is 550mm, F# is 6.5 and field of view (FOV) is 76 degrees. The system adopts some freeform surfaces. We discuss the problems we noticed in processes of design, manufacture, measurement and alignment, and the solutions. At last, the periodical research result and the expected performance are given.

In order to determine the vibration effects on performance in optical system, a simple vibratory model is proposed. The model suggested is compared with FE model. Both models are validated by modal tests for an existing simple optical system. The material properties of adhesive, which play an imported role in the vibratory model of an optical system, are found experimentally by using a simple test setup. The model suggested is used to investigate the dynamic behavior of the optical system under random vibration load conditions. It is concluded in this study that the analytical model suggested can successfully be used in preliminary design stage of simple optical systems when optical housing and lens behave rigidly in the frequency range of interest.

Introducing the desired amount of distortion in an optical system is possible and relatively straight forward for optical designer. Known f-theta lenses used in laser scanner system is one of the most popular lenses of this type. With the development of DWDM system, compact spectrometer and various grating based devices, the interest in solving optical problems with innovative optical design has been a revival. On the other hand, it is possible to simplify considerably the task of the software by designing more sophisticated optical element. The F-sin(theta) lens is such a device which can be used in various grating based devices to improve the performance. This optical device is intended to provide a new lens or lens group which can be used with a diffraction grating to provide a linear output plane with the wavelength (lambda), but also with the order of diffraction (m), or with the grating spatial frequency, or with the inverse of the index of refraction (l/n). Based on theoretical consideration, we calculated which amount of distortion is desired to get linear output plane for a grating based device. We present singlet. achromatic doublet and mirror having this characteristic. These F-sin(theta) lenses present satisfactory distortion charateristic and have an improved correction for the curvature of image plane. F-sin(theta) lens will be also name F-lambda lens.

We have designed a light-guide for lighting applications, including automotive headlamps. The light-guide is designed based on a free-form slab. Our intention has been to optimize the design for creating legal patterns. One of our objectives has been to investigate how the changes in the shape of the freeform light-guide affects the light pattern, and how the light source geometry affects the design. For prototyping purpose, we use a particular polymer that exhibits optical performance close to acrylic (PMMA).

An original method to enable the exact solution for the noncemented two-lens objective by means of any number of simultaneous non-linear equations is described. The method is limited to spherical surfaces without decentrations. Separations and refractive indices of glasses are fixed. Ail curvatures of surfaces are indirectly determined in the final stage. The typical meridional aperture aberrations deal with aplanatic and achromatic conditions. Essence of the method relies on formulation functions which contain trigonometric expressions and are nested up to certain depth. The method uses the advanced professional mathematical software which is indispensable for serving the non-linear system of equations. Numerical examples confirm the helpfulness of the method.

In missile applications, new counter measure methods are getting more complex. To discriminate and detect counter measure and to understand target signature from scene is getting harder. Because of all that concerns, using triple-mode seeker for a system solution is a good solution for system total performance. By this way, tri-different wavelength could be used for same system and same scene. In this study, triple mode system's optical designs have been made for mid-wave infra-red imaging, long-wave infra-red imaging and short-wave infrared imaging. optical designs performances have been illustrated in simulation results. Finally, conceptual design of triple mode seeker will be summarized.

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.

The main characteristic of adaptive lenses is to change their shape, and consequently their focal length, by modifying their physical parameters. On the other hand, Fresnel lenses have such features as large aperture, short focal length, they are slim and reduced in size. These kind of lenses have become very popular due to their applications, such as in compound eyes, optical communication systems, photolithography, imaging systems, etc. Nowadays, several kinds of tunable lenses exist such as those made with dielectric materials, lenses that change their focal length by varying the refractive index of the material, liquid lenses composed by elastic membranes and solid elastic lenses. In this work, we present the design, simulation of the mechanical behavior using Finite Element Method (FEM) and cost analysis of an Adaptive Fresnel lens made of an elastic material, together with a mechanical mounting system. Our study considered the use of design thinking methodology to obtain the best optical design at minimal cost. Analysis, results and future applications are presented.

Most lens design problems involve the time-consuming task of finding a proper starting point, that is, a lens design that approximately fulfills the desired first-order specifications while decently correcting aberrations. In recent work, a fully-connected (FC) deep neural network was trained to learn this task by extrapolating from known lens design databases. Here, we introduce a new dynamic neural-network architecture for the starting point problem which is based on a recurrent neural network (RNN) architecture. As we show, the dynamic network can learn to infer good starting points on many lens design structures at once whereas the previous model was limited to a given sequence of glass elements and air gaps. We also show that a pretrained RNN model can generalize its knowledge over new lens design structures for which we have no reference lens design and obtain a significantly better optical performance than a RNN trained from scratch.
