Title: LIQUID EXAMINATION DEVICE AND LIQUID EXAMINATION METHOD
Abstract:
Provided is an examination technique that can quickly and reliably examine, from the outside of a container, whether a liquid which fills the container contains an explosive or the like, without being influenced by such things as the light transmissivity or size of the container, or the amount of liquid remaining in the container or the position of a label. In the present invention, a liquid examination device is formed by integrating the following: a near infrared-light examination device that examines whether a liquid which fills a container contains an explosive, an explosive raw material, and/or an illicit drug by projecting near infrared light into the liquid from outside of a light transmissive container, receiving the near infrared light which passed through the liquid or the near infrared light which was scattered by the liquid, and analyzing the absorption spectrum of such light; and an ultrasonic wave examination device that examines whether a liquid which fills a container contains an explosive, an explosive raw material, and/or an illicit drug by receiving the reflected waves of ultrasonic waves projected towards the liquid from outside of a metal container, and analyzing the ultrasonic wave speed of such waves.
