Abstract
High-resolution spectroscopy using spatial heterodyne spectrographs (SHS) offers exceptional performance and cost-effectiveness in the UV-Vis region for space missions.SHS instruments deliver high-resolution capabilities with larger etendues compared to similar instruments.This study presents a Python-based SHS model with a web interface for star selection, parameter generation, and 2D interferogram creation.The model also provides system optimization results and SNR values for aiding parameter selection.SHS proves to be a versatile and effective tool for numerous scientific applications, such as studying atomic and molecular emissions from comets, planetary atmospheres, Earth's atmosphere, the Sun, and the interstellar medium (ISM).
