As part of the effort to localize the technology of the measurement of aspheric
optical surfaces within the available capabilities locally, we conducted a theoretical
study that includes the importance of these surfaces and design algorithm to achi
eve
better performance of optical systems, in addition to studying the most important
methods of measurement, with the allocation of the bulk of the research on the study
of optical systems that called "Optical Corrector", And methods of its investment,
and then seek to develop special optical correctors.
According to the importance of economic solar ponds in domestic and industrial
daily practical applications and its international widespread, this created the basis of an
experimental study on a prismatic solar pond. It is internally painted in bla
ck with a surface
measurement of (1m2) and a lower measurement of (0.42m2) and 1m deep. It constitutes
four levels of gradual salinity separated by transparent glassy tablets /home glass/ of
(6mm) thickness. On its lower level, a black solid mass is placed (black volcanic stones of
equal dimensions; almost around 1cm). Upon studying the temperature and the stored
thermal amounts of via subsidiary time every day from 9 am until 5 pm, the average rate of
stored thermal amount each hour calculated according to the following equation:
(Q = m.Cp.ΔT) during six months (February until July 2016) was:
9962.445 KJ, 9516.28 KJ, 10783.471 KJ, 9765.836 KJ, 14010.393 KJ, 12164.320 KJ
respectively.
