ABSTRACT:
A spectrometer provides a substantially simultaneous electronic output over a broad spectral range while maintaining a relatively high resolution. The spectrometer uses a fiber-optic transformer having an arcuate one-dimensional input region, associated with the image plane of a Rowland circle, and produces a rectangular two-dimensional output image, for illuminating the active area of a two-dimensional CCD sensor.
