If you have been flying since 9/11 you know that not even bottled water is accepted on planes. Airport security got really strict with bottled containers but lets hope it will all be history pretty soon. The INSIGHT100 airport security scanner is able to identify the liquid contents of various containers. The scanner utilizes Spatially Offset Raman Spectroscopy, or SORS. The process begins with security personnel placing an individual container inside the microwave oven-sized device. Then, the system shines a near-infrared laser into that container at various locations. Some of that light is reflected back to the device by the liquid. The wavelength of that light, however, is shifted by energy levels of the liquid’s molecules. By assessing the wavelength shifts of those various light readings, the machine is able to identify what the liquid is – within five seconds, to boot. According to the manufacturer that INSIGHT100 has a false alarm on 0.5% of the trials and works with clear, colored or opaque plastic or glass containers. It can be used on bottles up to three liters (0.8 US gallons) in size, and the height of its reading device can be adjusted for partially-filled containers.
