Space Observatory Relies on Precise Mirror Optics

摘要

Imagine a golfer making a hole-in-one over an 80-mile-long fairway. The 0.1-arc·sec angular accuracy needed to make this shot was achieved using electro-optical metrology by engineers atEastman Kodak Co., Rochester, NY, during the assembly and alignment of eight cylindrical mirrors for the National Aeronautic and Space Administration's (NASA) new space-based x-ray imaging observatory.
