A technique is proposed for the determination of the tritium to deuterium density ratio in ITER using collective Thomson scattering at a wavelength of 10 {mu}m. The measurement is made by viewing the component of scattered laser power nearly perpendicular to the magnetic field giving rise to ion cyclotron modulation of the scattered spectrum. The tritium/deuterium ratio may be inferred by a deconvolution of the scattered laser power. Due to the narrow bandwidth of the scattered signal and the spatially varying magnetic field, a narrowband heterodyne imaging array receiver will be required to observe the scattered spectrum. {copyright} {ital 1997 American Institute of Physics.}
