Abstract: With the development of high resolution sensors in remote sensing satellites the shadow phenomena has appeared clearly in satellite image. The shadow is a separated feature in the satellite image, some time it may be considered as a problem due to the loss of ray information at the shaded region, other may be considered as a criteria to the height of the body which has a shadow. The length of shadow depends on the height of the body, location on the earth surface, and the sun location in sky at the imaging time. The sun location is varying every hour during the day and every day during year. These varying is calculated by complex astronomic equations. In this article we simplified these calculation to just on equation depend on one parameter, and examine this equation by a field measurements. The suggested equation is sum-sine equation with an enough accuracy to be used in civil, ecological, gardens designing near the high buildings, or architectural purposes. The equation can be used to estimate the building height from the shadow length in the satellite image, as will as it may used to estimate shadow length from the known body height on the earth.

Abstract Using ZEMAX software, a designing of beam splitter in a different wave length is adapted in this paper presented. The design was made in a visible band (F=0.486 μm), (d=0.587 μm), (C=0.656 μm), and the optical properties of the polarizing beam splitter have been studied in order to modeling and manufacturing the prism of beam splitter. Different graph plots are using as a criteria. The Results shows that the optimization design can be done by ZEMAX software in order to be simulated and tested in laboratory.

Abstract Computer simulation has been used to enhancement the quality of astronomical image formed by a singlet eyepiece. And by examining the Zernike coefficient values of an aberrated image wave-front for this system and utilizing them to show the effect on image quality. The aim of this research is to measure Zernike coefficients and added them to the lens surfaces of eyepieces, in order to avoid the atmospheric turbulence .The simulations carried out with ZEMAX-EE Optical Design Program (Version 2009) in three different wave length (0.486133, 0.587562, 0.656273). The results show an enhancement on image quality by means of FFT MTF, OPD Fan, RMS field and FFT PSF.

Abstract In this work, an examination upheld data of air temperature , wind speed, relative humidity, and Rainfall gathered from an Automatic Weather Station of the observatory of Kufa University . These station is set inside the Faculty of Science, wherever the outcomes demonstrate a run of the mill drawback inside the programmed stations portrayed by an achievable alteration inside the normal level of the predisposition once a disappointment inside the station. The outcomes demonstrate a typical issue in the programmed stations described by a conceivable change in the normal level of the inclination after a disappointment in the station.
