Paper Abstract

In the present work we present a novel approach of the null-screen test for testing a Parabolic Trough Solar Collector (PTSC) that involves the usage of custom designed dynamic patterns projected on a LCD display, in a new off-axis disposition that allows for more consistent retrieval of information as well as the ability to extract larger amounts of data in each test. We present images depicting an ongoing test that show clearly the advantages of this method compared to earlier versions of the null-screen test for the same collector.
