Abstract: PURPOSE: A device using a linear optical fiber bundle for optically detecting dangerous liquid is provided to determine whether liquid contained inside a container is dangerous or not by using a spectroscopic analysis method. CONSTITUTION: A device using a linear optical fiber bundle for optically detecting dangerous liquid includes a target object arrangement unit (C), a laser emitting unit (50), a semi-cylindrical collecting lens (20), a linear optical fiber cable (30), and a spectrum determining unit (60). The target object arrangement unit is formed into a chamber form of which an internal space capable of placing a container (10) containing liquid is opened/closed by a cover or a lid, and the inner surface thereof is covered with a black body. The laser emitting unit is connected to the target object arrangement unit so that continuous wave lasers (40) of a frequency of 532 nm, which has energy of 150 mJ or less, are incident into the internal space of the target object arrangement unit. The semi-cylindrical collecting lens collects Raman signals generated when the continuous wave lasers are penetrated through the liquid inside the container. A collecting lens head (31) and a spectrum determining unit head (32) are arranged on both end portions of a linear optical fiber bundle (33) composed of a plurality of linear optical fibers respectively. When the Raman signals are inputted, the spectrum determining unit splits lights with a light splitter (62) and compares and analyzes the split lights with a dangerous material spectrum information stored in the database of a computer (63), thereby determining whether the liquid inside the container is dangerous or not.
