Cotton maturity is a fiber parameter related to thickness of the cotton fiber cell walls. There is a need for developing quick, non-destructive methods for measuring fiber maturity. In response, infrared (IR) methods of estimating fiber maturity have been proposed. The current study seeks to expand IR-based determinations of fiber maturity using an IR macro sampling chamber equipped with a Focal-Plane Array (FPA) detector. The systems is capable of simultaneously examining cotton fibers bundles at 64 sampling points. Vibrational spectra and chemical images were acquired by grouping data points in the FPA. Grouped data presented reduced spectral noise and enhanced chemical images. The established method was used to estimate fiber maturity in a variety of international cotton standards. Imaging studies were quick and provided a distribution of cotton bundle composition and fiber maturity.<br/>
