Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
A METHOD OF OBTAINING SPECTROSCOPIC INFORMATION IN A FORM SIMILAR TO THAT OBTAINED FROM AN INTERFERENCE SPECTROMETER BY MEANS OF A DISPERSION SPECTROMETER, WHICH COMPRISES: SUBDIVIDING LIGHT AT AN ENTRANCE PLANE OF A DISPERSION SPECTROMETER INTO AN ARRAY OF STRIPS; FOCUSING THE DISPERSED LIGHT EMERGING FROM THE DISPERSION SPECTROMETER INTO A MULTIPLICITY OF DISPLACED IMAGES OF SAID ENTRANCE SLIT APERTURE ARRAY UPON AN EXIT PLANE WHICH CONTAINS AN ARRAY OF STRIPS SIMILAR TO THAT AT SAID ENTRANCE PLANE; AND SYNCHRONOUSLY ROTATING THE ENTRANCE AND EXIT SLIT APERTURE STRIP ARRAYS WHILE MAINTAINING THE PLANES OF SAID STRIP ARRAYS IMAGED ON EACH OTHER; WHEREBY VARYING DISPLACEMENTS OF THE DISPERSED LIGHT EMERGING FROM THE ENTRANT SLIT ARRAY RELATIVE TO THE EMERGENT SLIT ARRAY, UPON SUCH ROTATION, PRODUCE TRANSMISSION VARIATIONS WHICH, BY CONTROLLING THE RATE AND ECCENTRICITY OF ROTATION DEPENDENT ON THE DISPERSION, CAN BE CAUSED TO SIMULATE AN INTERFERENCE SPECTROMETER OUTPUT, DIFFERENT ROTATIONAL POSITIONS OF THE APERTURE STRIPS CORRESPONDING TO DIFFERENT RETARDATION SETTINGS OF AN INTERFERENCE SPECTROMETER.

Claim 3
Dependent Claim
51 words
A SPECTROMETER COMPRISING: AN IMAGE FORMING OPTICAL SYSTEM INCLUDING DISPERSIVE MEANS FOR DISPLACING IMAGES FORMED BY SAID SYSTEM TO A DEGREE DEPENDENT UPON THE WAVELENGTH OF THE IMAGE CARRYING RADIATION; AND AN APERTURE ARRAY OF LINEAR PARALLEL SLITS FOR MASKING BOTN INGOING AND OUTGOING DISPERSED RADIATION, SAID ARRAY BEING SYNCHRONOUSLY ROTATABLE.
