# Tailoring the V-Model for Optics: A Methodology for Optomechatronic Systems
## 5 Summary and Conclusions  
The increasing complexity of high-resolution lighting systems in combination with the demand for high optical efficiency and image quality lead to the fact that established methods like the VDI guideline 2206 reach their limits. Therefore, in this contribution we introduce a V-Model to develop optomechatronic systems, in which both the concept-defining properties of the domain optics and the effect of these systems on humans are taken into account. Concretized in the phases of system design and domain-specific design by methods for the preliminary and detailed design of high-resolution lighting systems, we show how the conflict of objectives between high optical efficiency and image quality can be addressed. For this purpose, the concretization of principle solution variants is extended by specific design steps for high-resolution lighting systems within the phase of the system design. As a result, various preliminary designs of the high-resolution lighting system are available by means of beam models, which are used as the basis to create computational models of the overall optomechatronic system. The subsequent optional analysis of cross-domain interactions is used to derive solution variants of the overall system. The further elaboration of the selected solution concept in the phase of the domain-specific design is made concrete for the domain optics by the method for the sequential and non-sequential detailed design of high-resolution lighting systems. Finally, a detailed design of the optical system is available for the high-resolution lighting system, in which both influences on the image quality and optical efficiency can be quantified as well as measures to increase them are known (cf. Figure 9: Design step \"Evaluate image quality of the SC-Design\" resp. \"Evaluate efficiency of the NSC-Design\"). Once the manufacturing documents have been prepared and all components in the optical, mechanical, electronic and software domains have been procured, the next stage is system integration and property validation. In this process phase, the components of the system are first successively assembled into subsystems, which are then used to set up the overall system. The final property validation of optomechatronic systems is carried out taking into account interaction with humans. Finally, the integrated process model is illustrated by practical application examples from research projects in the works of [PERSON] and [PERSON] [9; 17]. Using the example of the cross-domain solution concept from the work of [PERSON] [9], restrictions are discussed with respect to the conflict of objectives between optical efficiency and image quality using standard components to realize the optical system. In order to demonstrate opportunities to address this conflict of objectives by using tailored optical elements, the non-sequential detailed design of a high-resolution lighting system from the work of [PERSON] is analyzed [17]. In this contribution, the process to develop optomechatronic systems of [9] by [PERSON] is presented, which can be extended by specific adaptations of the process phases. Which process phase and which steps within the process phase have to be adapted is significantly influenced by the main function of the optomechatronic system to be fulfilled (cf. Figure 1). For example, the system in [5] by [PERSON], [PERSON], and [PERSON], referred to in Section 1.1, requires an adapted approach for the preliminary design of the optical system. With the objective of increasing the penetration depth for non-invasive imaging in the field of medical diagnostics using a light modulator, the main function \"Measure\" is realized. Besides light generation and modulation, optical elements for beam splitting and polarization as well as a spectrograph are used for this purpose. The selection of a suitable spectrograph as well as elements for beam splitting (beam splitting cubes, beam splitting plates, etc.) and polarization (dichroic polarizers, reflective polarizers, etc.)
