摘要：
A smoke detector is shown in which smoke particles are detected by the collection and detection of blue light emitted from a radiation source (3) and scattered by the particles. The emitted radiation (7) is passed into a volume (9) and is scattered by any smoke particles present. Scattered radiation is collected by an ellipsoidal mirror (13) and focussed on a silicon photodiode (15). The light collected by the mirror (13) has been scattered through angles substantially less than 45 DEG and preferably between about 10 DEG and 35 DEG .
