A Laboratory Evaluation of the Suitability of a Xenon Flashtube Signal as an Aid-to-Navigation

Abstract

Single flick xenon flashtubes have periodically been used by the U.S. Coast Guard as visual signals on marine aids-to-navigation. Their deployment has met with mixed responses. The conspicuity of the signal is excellent; it stands out among other visual signals, both flashing and steady lights. However, the flick is apparently too short, approximately 100 micro sec, for the mariner to fixate on it. He, therefore, is unable to make an accurate judgement concerning the distance to the light. This thesis utilized a Howard-Dolman Box to examine the depth perception of subjects under various flashing light conditions.
