Do parallel rays incident on a parabolic mirror meet at a pt. even if they're nt parallel to the prncpl axis?

I'm designing a mechanism on a Parabolic Solar Collector for tracking the solar motion. Just wanted some help with the geometry of reflecion frm a parabolic collector at diff angles of incidence

I haven't done any math to prove it, but my intuition is saying that a non-axial refection from a parabolic mirror results in a (curved?) focal line instead of a focal point.

Polarimetric Studies of the Solar Atmosphere $125.85 This book describes the design and development of an instrument called the Solar Vector Magnetograph or SVM. This instrument maps the magnetic field of the solar active regions. The magnetic field of solar active regions is responsible for the eruptive phenomena on the sun which expel large amounts of highenergy particles and radiation in the interplanetary space posing danger for human activities in space. The careful measurement of solar magnetic field is very important to track its evolution which may be useful for forecasting the solar eruptive events. The instrument SVM was developed by Dr. Sanjay Gosain during his Ph.D. at Udaipur Solar Observatory, India for which he received best thesis award by Astronomical Society of India. This book describes how the highcadence magnetic field measurements can be done by using a tunable FabryPerot etalon and a polarimeter. This book is useful for any solar astronomer who wishes to develop an instrument for measuring solar magnetic fields or wishes to understand how solar magnetic field is measured using Zeemaneffect diagnostics. The techniques of optical polarimetry is also discussed in depth.

A Survey of Passive Solar Buildings $35.09 This publication of passive solar projects built in the United States has been prepared to document the state of the art in passive solar design. Passive solar heating and cooling can provide a major percentage of the buildings energy requirement, while at the same time representing a heightened level of involvement for the architect in the design stages of the building. The full potential of this passive conditioning depends on a sensitive awareness of the relationship between climate, comfort, and the thermal characteristics of buildings and building materials. Passive solar systems are often misunderstood and vaguely defined. Many of the approaches to passive solar heating and cooling are at rudimentary stages, with little performance data and evaluation, few modeling techniques, and minimal published information. Yet for the building designer and the occupant, these concepts have major implications in the design and use of buildings. The purpose of this publication is to offer a working definition and a basic understanding of a number of existing applications of passive solar designs. Methods of passive solar design are not presented in this publication; nor are rules of thumb or passive solar assemblies and components. These subjects will be addressed in later publications. A reference bibliography has been included to assist the reader who desires more information and to stimulate additional individual research and testing. Passive design techniques can be integrated in an additive fashion in more typical buildings but this challenge for now, is left to the reader.

Solar Water Heating in Dragash Municipality, Kosovo $106.74 Water has been heated with the sun almost as long as there have been humans, but it is not until recently that more advanced and effective solar water heating systems have become common, and they are still gaining ground. Through the years new systems and new solar collectors have been developed. In Kosovo, however, not much attention has been paid to replace fossil fuels with renewable energy sources and solar water heating systems is a new concept. However, a solar water heating system has been installed at the hospital in Dragash Municipality in southern Kosovo. The system is a pilot project, to see how well solar energy can be used in this area. This thesis examines the existing solar water heating system at the hospital in Dragash. The possibilities of using the fundamental principle of the solar water heating system at the hospital on residential houses in Dragash is looked into. The total annual incoming solar radiation for one square meter is calculated. The environmental, social and economic effects of solar water heating in Dragash is considered and discussed. Economic calculations are made on the effects of installation of solar water heating systems. Author: Dahl H.
