pinhole/occulter facility, describe the basic concepts and their implementa-tions, and present one possible strawman configuration of instruments. Section VI presents results of the initial feasibility studies and parts of the contract reports that are deemed particularly valuable in assessing the merits of the pinhole/occulter facility by: 1. The Pinhole/Occulter Facility The Pinhole/Occulter Facility Hudson, Hugh S.; Davis, John M. To image X-radiation efficiently at energies above about 10 keV requires To image X- radiation efficiently at energies above about 10 keV requires the use of "shadow optics" use of "shadow optics" techniques. The Pinhole /Occulter Facility (P/OF) represents an application of these. Pinhole Occulter Facility Pinhole Occulter Facility Dabbs, J. R.; Tandberg-Hanssen, E. A.; Routh, D. E. Scientific Objectives Solar Observations Solar The scientific objectives for the Pinhole /Occulter Facility in solar astronomy can be for the Pinhole/Occulter Facility in can be The into three areas: solar activity, coronal structure and solar wind generation, solar. The Pinhole/Occulter Facility takes major steps in improving the angular resolution and the sensitivity over prior observations. In angular resolution, P/OF will give arc s as opposed to the 8 arc s of the Solar Maximum Mission (Van Beek et al., ); in sensitivity, P/OF has a.

The Pinhole/Occulter Facility. By R. P. Lin, E. Tandberg-Hanssen, R. M. Macqueen, H. S. Hudson, J. L. Kohl and J. R. Pabbs. Abstract. A large occulting system in space can be used for high resolution X-ray observations and for large aperture coronagraphic observations in visible and UV light. The X-ray observations can combine high angular.

The Pinhole/Occulter Facility uses an end-mounted pointing- control system to manipulate the by: 1. In recent years, X-ray astronomy has become an integral component of solar and celestial observing programs. The development of soft X-ray imaging by grazing-incidence optics, such as those flown on Skylab and the Einstein Observatory, has established soft X-ray telescopes as a major observational tool.

THE PINHOLE/OCCULTER FACILITY J. R. Dabbs, E. A. Tandberg-Hanssen, and H. S. Hudson October The frontispiece for NASA TP was inadvertently omitted in its recent publication. The attached photograph of the PINHOLE/OCCULTER FACILITY should be included as a frontispiece in your copy/copies of the report. Date issued: The technical basis for performing observations with a large occulting system in these three wavelength ranges is described as well as a pinhole/occulter facility presently being considered for Spacelab. Some indications about future developments are included. Turn your memories into beautifully simple lifestyle photo gifts. Carefully crafted for quality, with smiles % guaranteed. Browse our entire collection. The Pinhole/Occulter Facility is based upon a simple idea for obtaining high angular resolution in astronomical X-ray observations, for example for solar flares at energies >10 keV. The scheme uses a coded aperture device (multiple pinhole camera) with a large separation between the aperture encoder and the detector. Such an imaging device can have an angular resolution much better than 1 arc.
