Abstract
One century ago the Danish physicist C. Christiansen described some experiments in which he index matched various powders in mixtures of two liquids. He observed that a perfect match was only possible for one wavelength at a time due to the difference in the dependence of the refractive index on wavelength between the powder and liquid. In the experiments reported here, the powder has been replaced by a relief hologram. When immersed in liquid mixtures this diffraction grating can be made inoperative at a narrow band of wavelengths and tunable by varying the composition of the liquid mixture and/or changing an external parameter such as the temperature.
