Fresnel Reflections - RP Photonics

WebThe Fresnel design uses less expensive reflector materials and absorber components. It has lower optical performance and thermal output but this is offset by lower investment and operation and maintenance costs. The Fresnel system also provides a semi-shaded space below, which may be particularly useful in desert climates for agriculture. WebA straight line connecting the two-way time and frequency intersects the central line at the same point as a line connecting the average velocity and the Fresnel Zone radius. For example, a 20-Hz reflection at 2.0 seconds and velocity of 3.0 km/s has a Fresnel Zone radius of 470 m.
