In order to meet the requirement of miniaturization, high image quality and large field of view of monitor lens, based on the characteristics of monocentric lenses, and the development of curved image sensors, we designed a monitor lens optical system and all refraction surfaces and its curved image surface have the same spherical center. The monitoring optical system's FOV is 140°, the focal length is 7.88mm, the F-number is 1.50, and the total length is 14.47 mm. The monitoring optical system is up to 11-megapixel. The final design result shows that the MTF value is closed to the diffraction limit in the central field of view and the 0.7 field of view, and is greater than 0.59 at all fields of view. The RMS radiuses of different fields of view are all less than 1.1 μm . It can be clearly seen that the aberrations of each field of view are well controlled from the quantitative analysis of the transverse ray fan plot. The monitor lens has good performance in quite a large FOV with a miniaturization structure.
In this paper, the prism's static imaging relationship and dynamic imaging theory are used to express the influence of the prism on the optical path in an ideal state. At the same time, the influence of manufacturing error and position error of the prism on the optical path is also analyzed and the corresponding action matrix is deduced. The feasibility of using prism deflection to compensate for prism manufacturing error is discussed, which provides a feasible solution to the general problem, and the corresponding theories are illustrated using the right angle prism as an example.
Star sensor is a high accuracy sensitive instrument for attitude determination, and the optical system is an essential part of the star sensor. According to the user requirements and CODE V patent library, the optical lens of a star sensor with large relative aperture and wide-spectrum range is optimized. The final design consists of 8 spherical lenses. The focal length is 50mm, the relative aperture is 1/1.35, the field of view is 7° × 7° (the diagonal field is 9.9°), and the spectral range is 500nm to 800nm. The design results show the optical lens has good performance. The distortion is less than 1%, the energy concentration is more than 80%, and the MTF of all fields of view is close to each other. The energy concentration of the spot diagram on the off-axis field of view and the on-axis field of view remains basically the same. The optical system meets modern design requirements for the star sensors.
In order to meet the requirement of high image quality and super-wide-angle mobile phone lens, a super-wide-angle mobile phone lens with a curved image surface and 10 megapixels based on monocentric lenses is designed in the paper. The mobile phone lens is composed of 4 monocentric lenses. The focal length is 3.32mm, the F-number is 1.85, the FOV is 95° and the total length is 5.24mm. The final design shows that the MTF is larger than 0.52 in the 0.7 field of view and the MTF of the whole FOV is larger than 0.45 at 209 lp/mm. The MTF is larger than 0.3 in the 0.7 field of view and the MTF of the whole FOV is larger than 0.2 at 417 lp/mm. The RMS radiuses of different fields of view are less than 3 μm . The relative illumination values are greater than 0.6 in the full field of view. The optical system has good image quality.
