Open-source Python pipeline for optical performances and alignment analysis using ray-tracing tools

Le résumé fourni par la source

This paper presents a fast, accurate, and easily integratable open-source pipeline for analyzing optical system performance under mechanical and thermal perturbations. Built on the Batoid ray-tracing library, the method replaces complex multi-tool workflows with a unified Python-based framework. It processes design variations such as alignment errors, rigid-body motions, and surface deformations-imported directly from standard finite-element-analysis (FEA) outputs-and applies them to the optical model. The pipeline includes automated conversion of Zemax prescriptions, deformation ingestion, system updating, and extraction of optical diagnostics. Using a three-mirror anastigmat telescope and sample Structural-Thermal-Optical-Performance (STOP) data, the paper demonstrates the pipeline's ability to rapidly compute wavefront error, boresight shifts, optical motions, and surface deformation impacts. This approach enables fast feedback loops for design teams and accelerates the development.
