Fabrication of the 6 . 5 m primary mirror for the Multiple Mirror Telescope Conversion
نویسندگان
چکیده
The Steward Observatory Mirror Lab is in the process of fabricating the 6.5 m mirror for the conversion of the Multiple Mirror Telescope (MMT) to a single primary mirror. For this purpose the Lab has developed a versatile polishing system built around the stressed lap polishing tool. The system must produce an f/1.25 parabolic surface with an accuracy corresponding to 0.09 arcsecond FWHM seeing and 1.5% scattering loss at 500 nm wavelength.

Interferometric hartmann wave-front sensing for active optics at the 6.5-m conversion of the multiple mirror telescope.
A little-used interferometric modification to the classical Hartmann optical test is being used for active optics corrections at the 6.5-m Multiple Mirror Telescope (MMT) Observatory. The technique produces compact interference spots whose positions depend on discrete wave-front phase-difference errors. A diffraction model illustrates the formation of interference spots. The limitations on wave...

The new findings show that the brain has group of neurons which has mirror properties; these neurons called mirror neurons. Despite the fact there is no reliable physiological symptoms associated with Autism , it seems deficit in the mirror neurons in the prefrontal associated with this disorder. The purpose of this survey was finding the evidence on disordered function of the neurons in the ch...
متن کاملNew method for characterizing the state of optical and opto-mechanical systems
James Webb Space Telescope Optical Telescope Element (OTE) is a three mirror anastigmat consisting of a 6.5 m primary mirror (PM), secondary mirror (SM) and a tertiary mirror. The primary mirror is made out of 18 segments. The telescope and instruments will be assembled at Goddard Space Flight Center (GSFC) to make it the Optical Telescope Element-Integrated Science Instrument Module (OTIS). Th...
متن کاملA Power Efficient Gain Enhancing Technique for Current Mirror
This work introduces a new and simple method for adjusting the gain of current mirror. The major advantage of the proposed architecture is that, unlike the conventional variable gain current mirror, it does not need the change of the biasing current to adjust current gain. Therefore, the power dissipation remains constant in all of the gain settings. In addition, the proposed variable gain curr...
متن کاملImmediate Effect of Mirror Therapy Using Pegboard Training on Hand Function and Muscle Activities in Individuals with Asymmetrical Hand Function
Objectives: Hand function is critical for daily life and work, especially with the use of electronic devices. This study determined the effect of mirror therapy in individuals with asymmetrical hand function. Method: Forty-two men with asymmetrical hand function were recruited. All participants were randomly divided into two groups: sham control (n = 21) and mirror therapy (n = 21). Both group...
