High angular resolution studies of celestial X ray sources and design of aspect camera, proportional collimators, telemetry, and attitude control systems
Reflector antenna of the parabolic type offers complete control of its aperature illumination function. The antennas beam width can be changed easily by excitation of various amounts of the line-source feed. The conical reflector collimates a beam when the feed complies with certain geometric constraints.
System will collimate and direct an argon laser beam with high angular tracking accuracy at objects on the moons surface. It can be adapted to missile and satellite tracking.
Design and performance of collimated beam solar simulator
Spectrum of high energy X ray flux from Sco XR- 1 during balloon flight using active collimator detector and graded shield detector
Diffuse cosmic X ray background measured during balloon flight with actively shielded and collimated detector
X ray source Cyg XR-1 angular diameter upper limit determined from balloon experiment data obtained with collimated X ray telescopes
Refractive indices for various glasses obtained as function of wavelengths and temperature, using spectrometer as collimator
Luminous tenuous collimated electron beam from plume of MPD arc in fiberglass vacuum tank, examining beam trajectory in geomagnetic fields
Diffusion filter comprised of small particles in colloidal suspension reduces the coherence of a laser beam used as a photographic light source. Interference patterns which obscure details in photographic film are eliminated, the intensity and collimation are moderately affected.
Screen permits front surface projection of collimated light beam under conditions of high extraneous illumination. Screen has high reflective efficiency over any desired viewing area. Its optical properties are maintained when moisture droplets are present on the external front planar surface. Surface is easily cleaned and maintained.
