Terahertz Intracavity Spectrometer

reportActive / Technical Report | Accesssion Number: AD1194545 | Open PDF

Abstract:

A hand-held sensing and alarm system is needed for ultra-trace concentrations of chemical gases, biological aerosols, and explosive vapors. Unprecedented sensitivity is required due to low concentrations and low vapor pressures for many targets of interest. Zyberwear has identified intracavity laser absorption spectroscopy (ICLAS) as a promising solution. Our working name "Hyperdog" anticipates its sensing capabilities for trace vapors. Hyperdog provides greater than kilometer effective optical path lengths in a device with centimeter dimensions.
