WebThe beam of laser light is shined across the path into some kind of receiver on the other side of the path. When the laser beam is broken, the alarm is triggered. This alarm can be located inside the house, or it can even be a text message sent to your cell phone. 2. Laser fence: Laser fences are essentially big nets of laser tripwires. They ... WebThe gas detector then modulates the emission wavelength of the LD so that the absorption line peak is kept at the center with 10 kHz, and irradiates the laser light to the space. This generates a 1f (10 kHz) component proportional to the light intensity, and a 2f (20 kHz) component via gas absorption if methane exists in the optical path.
