An original device for the automatic measurement of the luminance distribution in an observer's visual field

This work describes a new device that enables the photometric evaluation of an observer's visual field by measuring the luminance distribution. To provide an example of the applications, we have obtained the equivalent veiling luminance for different directions of the observer's line of vision. The results enable us to compare different luminous environments from direct measurements, without having to resort to theoretical methods. © 1996Peer Reviewe
