While some instrument requirements are levied on a per-pixel basis, efficiencies and economies can be gained by testing them in parallel. Furthermore, the use of detector arrays as imagers with extended targets enables the derivation of geometrical i

We have recently demonstrated the ability to measure the absolute change in optical power (focus) of a 152 mm diameter flat mirror in vacuum between room and cryogenic temperatures (133K) with a peak-to-valley measurement error of only 22nm. Such a m

Deep Impact Mission: Looking Beneath the Surface of a Cometary Nucleus ISBN: 1402035993
A suite of three optical instruments has been developed to observe Comet 9P/Tempel 1, the impact of a dedicated impactor spacecraft, and the resulting crater formation for the Deep Impact mission. The high-resolution instrument (HRI) consists of an f

Unpolished diamond turned mirrors are common for infrared systems. We report the successful use of unpolished mirrors in a visible spectrum, all aluminum telescope for the planned New Horizons mission to Pluto. The Ralph telescope is an F/8.7 Three M

Deep Impact is NASA's Discovery class mission to Comet Tempel 1. The probe will separate into two spacecraft, one of which will impact the surface and excavate a large crater. Optical observations will allow the mission to determine much about the co

Deep Impact is a NASA Discovery Mission to impact and observe the nucleus of Comet Temple 1. The instrumentation includes a 300 mm aperture telescope that will operate at 130K once in deep space. It is critical that the telescope mirrors maintain the
