Atmospheric Optical Propagationâ€â€?An Integrated Approach

Optical Engineering, 1982
The task of characterizing optical wave propagation through the earth's atmosphere under low-visibility weather conditions is extremely difficult; it requires, in essence, solution of the general multiple-scattering problem. This paper describes results from an integrated approach to propagation through the turbid atmosphere in which experiments are ...

CCD/Transit Instrument Deep Photometric And Polarimetric Surveyâ€â€?A Progress Report

Optical Engineering, 1984
We have previously reported on the conceptual design and predicted performance of a new type of dedicated astronomical telescope to be used for a deep photometric survey for galactic and extragalactic variability and polarization.' Data derived from this survey will be useful for a wide variety of astronomical investigations including the definition of

Strain Determination On Curved Surfaces Using Far•Field Objective Laser Speckles

Optical Engineering, 1982
Most of the laser speckle methods utilize subjective speckles in that speckles are recorded through a lens whose aperture determines the admitted spatial frequencies. Objective speckles are those intrinsically formed by the scattering wavelets. In this paper we propose the use of far-field objective speckles generated from a ground glass to measure ...

Design Of Null Lens Correctors For The Testing Of Astronomical Nnfit‘C

Optical Engineering, 1988
Some design examples are presented that illustrate the design of null correctors for the testing of strong aspherical surfaces such as those that are of interest in astronomical instrumentation. The design and analysis of an Offner corrector for an f/1 paraboloid is given.

Когнитивниот дефицит кај возраÑни пациенти по анеÑтезија во не–кардијалната хирургија [PDF]

open access: closed, 2017
Studies of the early 21st century indicate that the decline in cognitive functionis as a complication of anesthesia and operative intervention. Whether there would be changes and the amount of changes in mental status will cause a type of anesthesia is a
