It is proposed to design a test facility and develop a testing plan for a hypervelocity projectile launcher facility and for a target impact facility. the hypervelocity projectile launcher facility shall be capable of generating rod-like projectiles up to 4-feet long and up to 0.5-inch diameter, at… More

National technical systems (nts), under sponsorship of department of energy, has been successful in achieving super high efficiency holographic reflection mirrors. because the technology allows for adjustable reflection band pass wavelengths, both narrow band (delta lambda < than 20nm) and broadband… More

It is proposed to explore a new optical approach referred to as shearography for nondestructive inspection of bonded metallic/elastomeric interfaces. shearography is equivalent to a full-field strain gage; it reveals defects by looking for defect-induced strain anomalies. this approach is superior… More

Concepts exist for a new form of thermal rocket propulsion system. this system would require 10,000 to 1 solar energy concentration to heat the rockets working medium. holographic concentrators can be made to supply thermal wavelengths to the engine and visible wavelengths to solar cells. they would… More
