IEEE 4001-2025

This standard defines performance characteristics for hyperspectral imaging devices, usually referred to as hyperspectral cameras or imagers, as well as metadata for hyperspectral images, for a set of use cases defined to represent a wide range of applications. In the context of this standard, a hyperspectral camera or data set is defined as one in which pixel spectra are measured over a specified spectral range without gaps and with a spectral sampling interval not exceeding 1/30 of the spectral range. The standard considers cameras operating in the spectral range from 250 nm to 2500 nm wavelength, and applies to a defined set of hyperspectral camera architectures. Camera characteristics are defined to cover all key aspects of camera performance. Within the applicable camera architectures, the characteristics are defined so as to be directly comparable between cameras. Metadata are defined for describing camera-related aspects of a hyperspectral image, which can aid information extraction in the subsequent exploitation of the image.

This standard aims to serve camera manufacturers, buyers, and users of hyperspectral cameras by defining characteristics that give a comprehensive specification of camera performance, in a form that is directly comparable between cameras. The characteristics quantify the performance of hyperspectral cameras in such a way that the quality of the spectral image data can be robustly predicted from the camera specification. This standard also aims to serve users of hyperspectral images by defining image metadata that quantify camera-related image properties. A basic premise of the standard is that hyperspectral imaging, by its nature, is optical spectroscopy applied in a multitude of pixels across some scene or object of interest. Therefore, an important purpose is to specify the quality of the pixel spectra in a form relevant to spectroscopic interpretation as well as to provide metadata to aid such interpretation.
