These days, nothing lasts very long, and things often change for the better, but there are sure things in our community, such as this annual event, which has been going on for 25 years. The first edition in 2000 of the current developments in lens design and optical Systems engineering conference took place during International Symposium on optical science and technology, 30 July - 4 August 2000 in San Diego. Over 45 oral presentations and ten posters were presented. The chairs were Robert E. Fischer, Warren J. Smith, R. Barry Johnson, and William H. Swantner. The proceeding was numbered 4093 and 24 years later the number is 12666 (2023). This paper looks back on the great moments of our conference, its speakers, the subjects that have come and gone, and those that have remained.

In this work, an optical design approach is presented to design an ultrashort throw distance projection system by combination of an off-the-shelf refractive lens and two off-axis freeform mirrors. These two freeform mirrors are used to greatly shorten the projection distance by more than three times compared to conventional (rotationally symmetric) systems, while still maintaining a good imaging quality. Firstly, a direct design method that enables the simultaneous calculation of two off-axis freeform-profile mirrors by partially coupling more than three fields is introduced. The specifications of the conventional refractive lens are taken into account during this procedure. The pupil matching principle is applied to ensure good performance between the two sub-systems. The calculated mirrors then serve as a good starting point for optimization using commercial optical design software. To step from freeform profiles to freeform surfaces, the calculated two profiles are fitted into odd polynomials to evaluate the image quality and then re-fitted into XY polynomials for further optimization. Finally, the polynomial coefficients of the two freeform mirrors are imported into the optical design program. The merit function is built from RMS spot radii over the full field, and additional constraints are made for correcting distortion. After optimization, the calculated initial design quickly converges to a well performing imaging system. As an example, an ultrashort throw distance projection lens with a large 80-inch diagonal image at 400mm throw distance is designed, analyzed and compared with literature data. The values of MTF are over 0.6 at 0.5 lp/mm and the distortion is less than 1.5%: showing a very good and well balanced imaging performance over the entire field of view.

Several common impediments to successful lens design can be removed by application of new techniques. These involve using information that has long been calculated during the design process, but then discarded. Problems so addressed include the nuisance of discovering ray failures in the starting configuration, and that of tolerance desensitization, among others.

Genetic algorithm and its application in lens design is studied. A new algorithm is presented which includes a genetic algorithm (GA) and damped least square (DLS) method. The convergence property of GA in lens design is demonstrated. A GA. generated design is obtained without artificial intervention. The aberration correction has to be done by DLS, and the result is close to the starting configuration generated by GA.

ALGEBRAIC APPROACH FOR OPTIMIZING A TRIPLET lens

ISBN: (纸本)081941249X

Using the concept of matrix theory for lens design, a triplet lens can be replaced by a singlet lens which has an equivalent system matrix without changing its optical performance. Then, using third order Siedel's first aberration coefficient of the singlet lens is equal to zero, and the focal length and the physical length of the triplet lens are kept constant as constraints, an algebraic technique for optimizing a triplet lens is derived. Results show that this new optimizing technique is more effective than other conventional techniques for optimizing a triplet lens in the case of plane waves.

A zoom objective lens for a multi-layer optical recording has been designed. A newly proposed optical power arrangement enables varying back focal length while focal length invariant by a linear movement of single zooming component. The zoom lens is implemented into multi-layer and multi-bit holographic recording system employing 405 nm blue lasers.
