smoke detector chamber

macro image of the inside of a optical smoke detector chamber, the square elements house a photo emitter and photo receiver, when smoke enters the chamber light is scattered by the smoke and reflected into the receiver this triggers the alarm; to confirm the receiver is working correctly periodically the intensity of the emitter is increased this it detected by the receiver via reflections from the inside of the chamber to confirm that the receiver is correctly calibrated.
