Abstract

An extinction-type luminance measurement method using an inexpensive illuminance meter for low-light-level measurements is described. The method has application in night-time crime and accident scene investigations where poor and inadequate visibility may be a contributing factor. The meter is useful for measuring luminances under field conditions.
