Hyperspectral imaging calibration device

A disposable hyperspectral imaging calibration device comprising a reflectance standard having a predetermined reflectance or emission value at a plurality of known wavelengths over a known wavelength range.

A system for obtaining spectral information from the surface of a body part comprising:

• a. a calibrator that is form fitting to the body part to assume the shape of that part, and has at least one surface exterior to the body part that reflects light at two or more wavelengths;
• and
• b. a hyperspectral imaging instrument that has a light source and detector capable of detecting a two dimensional image at the two or more wavelengths and which further comprises a computer with a program for calculating an intensity variance as a function of the lighting conditions for a hyperspectral image, using detected reflectance values from the calibration pad at the two or more separate wavelengths.

A system for obtaining spectral information from the surface of a body part comprising:

• a. a calibrator that is form fitting to the body part to assume the shape of that part, and has at least one surface exterior to the body part that reflects light at two or more wavelengths;
• and
• b. a hyperspectral imaging instrument that has a light source and an imaging-quality wavelength-separation device that can image light at the two or more wavelengths to generate spectral information from the calibrator.

A system for obtaining electromagnetic spectral information from the surface of a sample comprising:

• a. a calibrator that is form fitting to the sample to assume the shape of that sample, and has at least one surface exterior to the sample that reflects electromagnetic rays at two or more wavelengths;
• and
• b. a hyperspectral imaging instrument that has a source of electromagnetic rays and an imaging-quality wavelength-separation device that can image reflected electromagnetic rays at the two or more wavelengths to generate spectral information from the calibrator.
