Improving the Design of Optical Devices Through STOP Analyses

There is an ever-increasing interest in structural-thermal-optical performance (STOP) analysis for optical systems, in which temperature change and structural loads affect the optical performance. The need for STOP analysis is greatest for extremely high-power systems, those in extreme operating environments, or those in which highly accurate predictions are vital. Examples include industrial fiber laser systems, space-based laser interferometers, balloon-based telescopes, and solar thermal desalination systems.

Using Simulation Applications to Develop Digital Twins

Simulations represent an important component of a digital twin. However, a physical twin must be included in a digital twin process. Measured values from this physical twin provide input to the simulation to assess how the device changes over time. These measurements provide important data to the simulation to enable engineers to develop their best understanding of the current state of the device. Thus, digital twins require functionality that traditional simulations developed during product design do not. Simulation applications (SimApp) provide an excellent tool for moving from a traditional simulation to a digital twin. The SimApp provides the opportunity to accept measurements from the physical twin as inputs to the digital twin. In addition, the SimApp can be programmed to execute comparisons of the digital twin and measured values form the physical twin, update the underlying simulation, and execute decision making on the current state of the device.
