This paper presents a Hadamard-multiplexed spectrometer based on an acousto-optic tunable filter (AOTF). The multifrequency capability of the AOTF enables it to be operated in a multiplexed mode. The AOTF can then be operated at lower power to obtain

Two identical Fourier transform infrared (FT-IR) field monitoring systems have been used to investigate differences in apparent plume concentrations as a function of height. The two systems also have been used to monitor the same plume simultaneously
