The development of a parallel-channel spectrographic detector: Applications to Raman scattering
Abstract
A parallel-channel detector was developed for use in visible and near infrared light scattering experiments. The design goal of obtaining quantum limited response simultaneously over 100 resolvable spectral elements was achieved. This level of performance allows a significant decrease in the time required to obtain a low light level spectrum, when compared to the acquisition times of conventional detectors. Details of the design, construction, and operating characteristics of the parallel channel detector were given, along with the results of Raman scattering measurements to determine: (1) the vibrational rotational temperature of a flame; and (2) the gas concentration profile of a gas dynamic system. Implications of these measurement techniques were discussed.
