Abstract: A method of determining olfactory perception signature of a subject is disclosed. The method comprises: providing the subject with a plurality of physical odorant samples for sniffing; for each sniffed odorant sample, presenting to the subject, by a user interface, a set of odorant descriptors and a respective set of rating controls, and receiving ratings entered by the subject using the rating controls. Each rating is indicative of a descriptiveness of a respective odorant descriptor for the odorant sample, thereby obtaining a set of descriptiveness levels for the odorant sample. The method also comprises calculating, by a computer, relations between pairs of sets of descriptiveness levels corresponding to pairs of odorant samples, to provide a vector of relations, wherein the vector represents the olfactory perception signature of the subject.

Abstract: Systems and methods for thermal sensing and imaging using the electro-optic effect. A thermal detection system comprises a temperature sensing element that includes an electro-optic (EO) material layer having a length axis and characterized by a temperature dependent index of refraction, an electrical mechanism for inducing a chance in the index of refraction, a laser beam propagating lengthwise through EO layer for probing the refraction index change, and a light intensity meter for measuring a laser beam intensity change caused by the temperature dependent refraction index change. Thermal imaging is obtained by using a pixel array of such thermal sensing elements. The intensity reading may be done in either a cross-polarizer or a Mach Zehnder Interferometry reading configuration.

Abstract: Methods for addressing a designated temperature operational range in a measurement that uses an optical readout of temperature and for enhancing that range are disclosed. The range is enhanced through providing at least one active detector with a periodic response, operative to provide a detector temperature through an electric field-dependent optical readout, and performing at least two measurements of the detector temperature to obtain a non-degenerate reading of an object temperature. The at least two measurements may include three same wavelength/different electric field measurements or two same electric field/different wavelength measurements.
