摘要
Optical fibers are utilized to provide high efficiency, spatially resolved coupling of light from collection optics to an imaging spectrometer. In particular, a micro lens array may be utilized to couple light from multiple spatial locations into individual optical fibers. At the opposite end of the fiber bundle, the fibers are packed tightly together to send the light into an imaging spectrograph. The light that enters this spectrograph maintains its spatial separation, for instance, along the array dimension and is spectrally dispersed, for instance, along a dimension orthogonal to the array dimension. This spatially separated, wavelength resolved light can then be recorded on a two dimensional detector such as a CCD camera.
