HYPERSPECTRAL IMAGING SPECTROMETER FOR EARLY DETECTION OF SKIN CANCER

摘要

An hyperspectral imaging system that may acquire high resolution spectral and image data in one step, avoiding image registration or image distortion problems, or the need for moving components. The invention employs an optical system that remaps light from normally contiguous elements of an object onto a planar detector in a way that provides interstitial space on the detector between the light from each object element. A dispersion element then generates a spectrum extending into the interstitial space so that the detector simultaneously captures imaging and spectral information. Eliminating the need for moving parts allows perfectly registered and skew-less image and spectral analysis of the skin and allows the practical construction of a rugged handheld device.
