A Tiny Optical Mask Could Help NASA See Other Earths
A precision optical vortex phase mask is emerging as a key technology for directly imaging faint Earth-like planets by canceling out the overwhelming light of their host stars.
Key Takeaways
- NASA’s planned Habitable Worlds Observatory would need to suppress starlight by a factor of ten billion.
- An optical vortex phase mask can cancel centered starlight through destructive interference.
