Special Issue Information

Dear Colleagues,

Optomechatronics is a blend of optics (and photonics), mechanical engineering (especially through precision mechanics), electronics, a strong component of control and automation, as well as IT. This formerly multi-disciplinary approach is more and more getting together in the last two decades as a single, complex problem-solving domain.
The aim of this Special Issue is to offer a forum for recent research in the field, but also for reviews and communications on relevant topics, concerning the development of macro- and micro-optomechatronic devices and systems (the latter as Micro-Electro-Mechanical Systems (MEMS)). Analytical studies, numerical simulations, and/or experimental approaches are considered. Such equipments (for example laser scanners and modulators of different types) usually include rapidly and/or precisely moving parts, therefore Finite Element Analysis (FEA) and sensors and control structures, respectively, have to be considered, and often kynematic and dynamic aspects, as well.
Optomechatronic applications are also targeted. They encompass areas as diverse as industrial (from measurement techniques to robotics and laser manufacturing, for example), biomedical (from imaging, for example, with Optical Coherence Tomography (OCT), to laser systems in medicine), remote sensing, as well as security & defence. We hope thus to offer the scientific community an insight into a rapidly evolving and fascinating field.
While this forum is open to all researchers, it also provides a selection of papers that will be presented at the 1st International Conference ‘Advances in 3OM: Opto-Mechatronics, Opto-Mechanics, and Optical Metrology’ , Dec. 13-16, 2021 (Timisoara, Romania), organized in celebration of 100 years of the Polytechnic University of Timisoara.

Off-Axis Three-Mirror Optical System Designs: From Cooke’s Triplet to Remote Sensing and Surveying Instruments

The off-axis three-mirror optical system is derived from the classical Cooke triplet or a derivative of the inverse-telephoto lens. By properly arranging an internal reimaging mechanism or altering the location of the optical stop, one can create different versions of three-mirror optical systems. They include very compact configurations and wide field-of-view imagers. Insights into the optical design process, manufacturing, stray light management, and remote sensing applications are presented. Full article

The integration of optical technologies into once purely mechatronic systems enables innovative functions, but simultaneously increases the complexity of previous mechatronic system development. Therefore, a process has been elaborated to develop these so-called optomechatronic systems by Knöchelmann at the Institute of Product Development at Leibniz University Hanover, which is based on the V-Model of VDI 2206 and can be applied to various fields of application. For a target-oriented development in a specific product context and for systems with competing main requirements, detailing and adapting the process is recommended. High-resolution lighting systems are one of them, where requirements for high optical efficiency and image quality lead to a conflict of objectives. Focusing on the optics domain, Ley elaborated methods for the preliminary and detailed design of high-resolution lighting systems to address the aforementioned conflict of objectives. This contribution focuses on the integration of Ley’s design methods into Knöchelmann’s process model within the phases of system design and domain-specific design, allowing us to analyze the impact of the system design on the fulfillment of main requirements to achieve an optimal solution of the conflict of objectives. To illustrate this, the integrated process model is described using an example from automotive lighting technology. Full article

Abstract
Rotational Risley prisms are one of the fastest two-dimensional (2D) optomechanical scanning systems. Their drawback is the strong non-linearity of the scan patterns they produce, in contrast to the most common (but slower) raster scanning modalities of 2D dual axis galvanometer scanners (GSs) [...] Read more.
Rotational Risley prisms are one of the fastest two-dimensional (2D) optomechanical scanning systems. Their drawback is the strong non-linearity of the scan patterns they produce, in contrast to the most common (but slower) raster scanning modalities of 2D dual axis galvanometer scanners (GSs) or Micro-Electro-Mechanical Systems (MEMS) with oscillatory mirrors. The aim of this work is to develop a graphical method, which, to our knowledge, we have introduced to determine and characterize, using a commercially-available mechanical design program (for example CATIA V5R20 (Dassault Systems, Paris, France)) to simulate the exact scan patterns of rotational Risley prisms. Both the maximum and minimum angular and linear deviations of this type of scanner are deduced theoretically to characterize the outer diameter/Field-of-View (FOV) and the inner diameter (of the blind zone) of its ring-shaped patterns, respectively. This multi-parameter analysis is performed in correlation with the shape of the scan patterns, considering the four possible configurations of laser scanners with a pair of rotational Risley prisms, as well as all their parameters: prisms angles, refractive indexes, rotational speeds, distance between the two prisms, and the distance from the system to the scanned plane. Marshall’s synthetic parameters are also considered, i.e., the ratios of the rotational velocities and of the angles of the prisms. Rules-of-thumb for designing this optomechanical scanner are extracted from this analysis, regarding both shapes and dimensions of the scan patterns to be produced. An example of experimental validation completes the mathematical analysis and the performed simulations. Full article
