Abstract (en)

[origin: WO0038283A1] A method and system provides for remotely sensing an environmental condition of an object (10). The method includes the steps of: providing the object (10) with an amplifying scattering medium (12), such as a dye and randomly distributed nanoparticles scatters, that exhibits a dependence of laser emission on at least one environmental condition; scattering medium with a pump laser beam (14A) for inducing a laser-like emission (14B) from the amplifying scattering medium; detecting a wavelength of an emission peak of the laser-like emission; and correlating the detected wavelength with a value of the environmental condition. The environmental condition may be temperature, and it is shown that there is a linear dependence in the 77K-380K range, with a slope of about 0.09 nm/K.
