Vision Equipment Comprising an Optical Strip with a Controlled Coefficient of Light Transmission
First Claim
1. Vision equipment comprising a translucent optical strip covering all or some of the visual field of the user of the said equipment and a device for projecting images onto the said strip in at least one zone of the visual field of the user, called the image-projection zone, wherein the optical strip comprises a plurality of zones covered by a layer of material with a controlled coefficient of light transmission of the photochromic type, a zone at least covering the image-projection zone andthe vision equipment further comprises a means for controlling the coefficient of light transmission comprising a means for activating the photochromic reaction onto at least one zone of the optical strip in order to control the coefficient of light transmission of the zone capable of receiving status information and of controlling the coefficient of light transmission of each of the zones and independently of one another as a function of the said status information.

Abstract
The invention relates to vision equipment including a translucent optical strip covering all or some of the visual field of the user of the said equipment and a device for projecting images onto the said strip in at least one zone of the visual field of the user, called the image-projection zone. The optical strip includes a plurality of zones covered by a layer of material with a controlled coefficient of light transmission, a zone at least covering the image-projection zone and in that the vision equipment also comprises a means for controlling the coefficient of light transmission capable of receiving status information and of controlling the coefficient of light transmission of each of the zones and independently of one another as a function of the said status information. The invention preferably applies to helmet visor equipment or head-up displays for an aircraft cockpit and to vision equipment in the motor vehicle field.
