Abstract :
Two attenuated total reflection (ATR) spectrometers for study of substances highly-absorbing in the terahertz range have been developed. First system is a home-made single-reflection silicon ATR sampling module with an isolated sample cell to VECTOR-30 and IFS 66v/S Bruker spectrometers. This module was used for the examination of biological objects, including human blood, grounded rat bone, and other tissues. Second system is an imaging terahertz spectrometer using a tunable 100-W terahertz free electron laser as a source and a 160times120 microbolometer focal plane array camera (repetition rate up to 90 frames/s) as a recorder.
