Smoke Detection
DIVERSE consultants work with several of the leading smoke detector companies in Europe. The requirement is to detect (at a particular level) the change in scattered (Tyndall Cell) or transmitted light. The principle relies on light scattering from fine smoke particles such as those found in the early stages of a fire. Smoke particles coalesce over time and form larger particles, so a more sensitive smoke detector will detect a fire earlier.

DIVERSE has designed optics for this application and provided assistance with the attendant electronic design.

Nuisance Dust
DIVERSE has been involved in evaluating dust collected on a sample paper. The density of the collection is used to make assessment of a legal nuisance.

Escapeway Exit Guide
DIVERSE provided the technology input for an award winning emergency exit direction indicator. The system is based on a laser pointing system that relies on optical back scatter from smoke particles. The scattered light, at near floor level, provides a direct and obvious indication of the escape route. As with the smoke cells this laser technique relies on Rayleigh and Mie scattering principles.
