Abstract
The contribution of integrating sphere speckle pattern on the instrument line shape of a Fourier- transform hyperspectral imager is investigated. A new measurement technique that minimizes the speckle effect is presented. This technique consists of agitating the sphere while integrating with the instrument camera. Experimental results are presented that show the speckle effect on the instrument line shape and how it can be removed. This work is motivated by the constant goal of better identification and correction of the instrument line shape.
