Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
In a spectrometer having a dispersive element to refract incident light into its' component wavelengths, a detecting means to determine which wavelengths are present, and a readout means for observing the wavelength information detected, the improvement comprising: a plurality of charge coupled devices positioned to have the refracted light from the dispersive element spread over them; control means for timing the charge coupled devices so that they are periodically scanned for information they contain, said control means being operatively attached to the charge coupled devices; amplifying means operatively connected to the charge coupled devices electrical output; a reference operated by said control means for comparing observed information on the charge coupled devices with known signals; and display means operated by the control means in conjunction with reception of signals from the reference and amplifying means.
