  • Methods and apparatus for collection of optical reference measurements for monolithic sensors
    Publication number: 20050007582
    Abstract: Methods and apparatus are provided for collecting optical data. Light is propagated through a reference sample from a source of light to a detector of light to produce a measured reference spectral distribution. Light is also propagated through a subject sample from the source of light to the detector of light to produce a measured subject spectral distribution. At least one of an intensity change and a wavelength shift between the measured reference spectral distribution and a stored reference spectral distribution is identified. The measured subject spectral distribution is compared with a stored subject spectral distribution associated with the stored reference spectral distribution. Such comparison includes accounting for the identified one of the intensity change and the wavelength shift.
