Design Concept



Opto-Mechanical System


The Opto-Mechanical System is a design scheme that maximized the modularity of the MODIS instrument to permit parallel fabrication, construction, and testing of the principal components (Mainframe, Scan Mirror, Passive Radiative Cooler, Optical Bench, and the Door Assemblies).

Technical Description

The modular construction of the instrument allowed the most efficient system integration and testing at the same time that it guaranteed that each sub-assembly met system requirements before being integrated into a cohesive instrument. This design system allowed MODIS scientists and engineers to ensure that MODIS was using the most efficient design before it being launched into orbit, where it would be too late to change anything.
