Abstract

The aberration compensation between binary optical Len and reversing prism of the hybrid telescope objective is analyzed under the guidance of aberration theory. Phase coefficients of the binary optical element are calculated. Primary configuration of telescope objective with reversing prism is ascertained. The optimized aberration results show that chromatic aberration is rectified exactly at 0.9 relative pupil height and maximal longitudinal spherical aberration is within range of tolerance 0.5 mm and maximal transverse ray aberration value is -0.115 mm. The MIF with aberration Compensation has been improved largely than the one without aberration compensation.

... The increment of functionality and structure complexity poses new challenges to system design. Du et al. [3] analyzed the aberration compensation of reversing the prism and binary optical lens and proposed a basic design to effectively improve the imaging quality of the system. Hu et al. [4] designed a sighting telescope with an exit pupil distance of 70 mm, which works in both the infrared light band at night and the visible band in daytime. ...

A sighting system based on the Galileo telescope structure generally suffers from the lack of a reticle, which poses great challenges to target aiming. In this work, a hybrid Galilean sighting system integrated with an augmented reality (AR) component is proposed, which produces an image of the reticle to serve as a reticle. The depth of the reticle can be adjusted flexibly to superpose with the image of the observed object. The designed system features a fourfold magnification, a large modulation transfer function (MTF)>0.3({\rm{MTF}}) \gt 0.3 ( M T F ) > 0.3 at 40 lp/mm, and a small distortion less than 0.3% in the full field of view. The superb imaging performance combined with the targeting function of the AR reticle renders the proposed design a powerful tool in the applications of target tracking.

A diffractive/refractive long wavelength infrared (LWIR) staring imaging system is designed to meet the commercial requirements. In this system the F-number is 1, waveband is 8-12μm, field of view is 12°, total track is 140 mm and the materials of the total two lenses are Germanium. The diffractive optical element (DOE) is fabricated on the convex of the second lens, and the DOE can be fabricated by diamond turning technology. The imaging quality is analysed that the Modulation Transfer Function (MTF) approaches the diffraction limit and the chromatic aberration is better corrected compared with the refractive system.

A hybrid diffractive/refractive achromatized telecentric f-θ lens system had been designed with a hybrid diffractive/refractive lens and three refractive lenses. The entrance pupil was placed at the focal plane so that it was a telecentric system. Contrast to the US patent 4, 925, 279, the lateral color reduced by one-order in magnitude (from 2.40 mm to 0.23 mm), and the maximal transverse aberration reduced from 260 μm, 1350 μm, 2090 μm to 5 μm, 250 μm, 318 μm for 0°, 14°, and 20° field of views, and the maximal field curvature reduced from 8 mm, 10 mm, 13 mm to 0.5 mm, 1 mm, 6 mm for the aforementioned field of views. The designed f-θ lens system could be applied in color scanning systems, such as color laser printers and color digital photo printers. It could also be applied in high energy scanning systems. When applying the designed hybrid diffractive/refractive achromatized telecentric f-θ lens system to the high energy scanning system, a big laser machine operating in one longitudinal mode could be replaced by a small multi-mode operating laser machine, and the system could be simplified greatly and the accuracy could be proved.

A hybrid diffractive-refractive infrared lens of germanium was fabricated by means of diamond turning, in which the diffractive surface was produced on an aspheric substrate. The test results for the hybrid lens and a comparative lens without the diffractive structure show that the diffractive surface is fabricated with good accuracy. It reduces the chromatic aberration of the single lens system, and significantly improves the image quality of the system, which corresponds well to the design result.

To form the theory and method of hybrid refractive-diffractive (HRD) optical design that can join to the Chinese conventional optical design system, the primary aberration theory expressed by PWC about HRD systems has been investigated, and the function relation between Seidel sums and P, W, C, between P̄∞, W̄∞, C̄∞, and the diffractive lens structure have been established. Using the PWC primary aberration theory and the ultra-high index design method, the original structure of the achromatic HRD medium-power Lister-type microscope objectives has been obtained. The result shows that its design of Seidel sums tallies with the theoretic value, so the PWC primary aberration theory and the ultra-high index design method about HRD systems proved to be effective. Comparing with the conventional two doublet design, it is shown our hybrid objective has a larger work distance and a higher imaging quality, and is suitable for mass production because the front is a singlet plastic lens.
