A Pocket-Sized Solid-State Optical Waveguide Chemical Sensor for In-Field Monitoring of Toxic Species

摘要

We are introducing a prototype design of a working model for a pocket-sized, rugged, low-cost personal dosimeter or point detector which utilizes an optical waveguide chemical sensor that we have recently developed. We believe that this prototype, made possible by the use of the hybrid integrated circuit chip, is a giant leap forward in the technology of point dosimeters. With the appropriate communications and power source, the output can be fed into building monitoring grids, emergency response databases, and even Internet-based national or international monitoring grids. The device is suitable for detecting toxic species, industrial chemicals, drugs, and explosives.
