Physical Measurement of Flashing Lights - Now and Then

Published

Author(s)

Yoshihiro Ohno

Abstract

This paper begins with a historical review of flashing lights and physical measurement of flashing lights since the time the Blondel-Rey equation was developed. Then the recent work on the physical measurement standards for flashing lights, developed in 1997 at the National Institute of Standards and Technology is introduced. The paper also discusses the physical requirements and practical aspects of measurements based on the four formulae(Blondel-Rey equation, Form Factor method, Allard method, and Modified Allard method) for effective intensity.
