One potential option was to insert corrective optics, lenses or mirrors in the telescope tube between the primary mirror and the secondary reflector. However the tube was too narrow for even the smallest astronaut to slither down it, leading to a search for a means of inserting the required corrective components into the tube.
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...

Mirror matter could also be responsible for the GZK puzzle [broken anchor]. Topological defects in the mirror sector could produce mirror neutrinos which can oscillate to ordinary neutrinos. [30] Another possible way to evade the GZK bound is via neutron–mirror neutron oscillations. [31] [32] [33] [34]

The technology goes back to 1973 with Harvey C. Nathanson's (inventor of MEMS c. 1965) use of millions of microscopically small moving mirrors to create a video display of the type now found in digital projectors. [1] The project at Texas Instrument's began as the deformable mirror device in 1977 using micromechanical analog light modulators.
