Imaging Spectroscopy with Monochrome CCD Cameras, 1997 Process & Product Quality Conference Proceedings
Conventional spectrophotometers usually measure an optical spectrum from a specified spot surface area. This is accomplished either with one detector scanning a narrow wavelength band or with an array detector. If one desires to measure different spatial locations the object must be moved incrementally in the X and Y direction several times. However, it is possible to obtain spatial information from a line geometry (X-axis) and spectral information from equally spaced points on the line with a common area detector such as a CCD camera.
