“…The equations and values of the focal lengths of individual optical elements concerning the transverse magnification were derived [69]. A paraxial and aberration analysis of an optical zoom imaging system consisting of three-element lens systems based on two adaptive liquid lenses (Optotune OL1024) and one classic solid glass lens made of N-ZK7 glass material was also studied by Miks et al The general formulas for calculating basic optical variables and structure parameters of the adaptive liquid lenses and the solid lens were derived [70][71][72][73]. They also conducted a theoretical analysis of the paraxial optical properties of the optical zoom lens system using three adaptive liquid lenses [74,75].…”

An optical zoom imaging system that can vary the magnification factor without displacing the object and the image plane has been widely used. Nonetheless, conventional optical zoom imaging systems suffer from slow response, complicated configuration, vulnerability to misalignment during zoom operation, and are incompatible with miniaturized applications. This review article focuses on state-of-the-art research on novel optical zoom imaging systems that use adaptive liquid lenses. From the aspect of the configuration, according to the number of adaptive liquid lenses, we broadly divide the current optical zoom imaging systems using adaptive liquid lenses into two configurations: multiple adaptive liquid lenses, and a single adaptive liquid lens. The principles and configurations of these optical zoom imaging systems are introduced and represented. Three different working principles of the adaptive liquid lens (liquid crystal, polymer elastic membrane, and electrowetting effect) adopted in the optical zoom imaging systems are reviewed. Some representative applications of optical zoom imaging systems using adaptive liquid lenses are introduced. The opportunities and challenges of the optical zoom imaging systems using adaptive liquid lenses are also discussed. This review aims to provide a snapshot of the current state of this research field with the aim to attract more attention to put forward the development of the next-generation optical zoom imaging systems.

“…The first-order characteristic analysis of optical system which reveals the difficulty and tolerance of the system at the beginning of design, is a central issue for an optical system design [13][14][15][16][17] . However, most previous studies focus on the challengeable narcissus suppression [18][19][20] , and the problem of cold shield matching is rarely reported as it is seems quite simple [21,22] .…”

To solve the problem of cold shield matching in a cooled infrared (IR) imaging optical system with aperture stop placed away from the lens, a pupil matching method based on the telecentric optical structure is proposed. The formulae of Gaussian parameters between the relay lens and the objective lens are derived by using the ideal imaging process. A specific discussion and numerical analysis are carried out. The objective lens is designed as image-space telecentric and the relay lens is designed as object-space telecentric to achieve the requirement that the aperture stop far away from the objective lens. And a specific designing example is added to show the effectiveness of the analysis.

“…The aim of our design method is to find first-order layouts that are adapted to the specific requirements of the respective application and the capabilities of the available tunable lenses. Although there is a wide range of literature discussing first-order calculation approaches for zoom lenses based on tunable lenses in detail, 22 the number of studies covering methods for a systematic search for layouts for this kind of zoom systems seems to be quite limited. Unlike other methods for classical zoom lenses, [23][24][25] our method sets the main focus on mapping the first-order solution space applying traditional thin lens aberration equations.…”

It is well known that tunable lenses, with refractive power that can be varied, e.g., by changing the curvature of a membrane, can replace the motion of lens groups in zoom systems. Similar to classical zoom systems, the performance of these systems is heavily influenced by the fundamental first-order layout. Moreover, the first-order layout sets the most important requirements for the employed tunable lenses. In this contribution, we present a method for the analysis of a large number of possible first-order solutions for typical requirements and for the selection of the most promising layouts. The first-order solution space is mapped, allowing the layouts to be automatically filtered and plotted depending on pre-defined characteristics. Ray tracing of the marginal and chief rays combined with the traditional thin lens aberration theory provide efficient estimations of the expected installation space requirements and performance for each firstorder layout. Using an example, we demonstrate good agreement between these estimations and the corresponding real lens layout, optimized by commercial raytracing software. The presented design method for zoom systems based on tunable lenses is compared with similar approaches for classical zoom lenses.
