孔子英语摘要：On-board ILS nsors for detecting illegal drugs and bad on intracavity lar spectroscopy (ILS) are provided for detecting the prence of drugs and their metabolized by-product vapors in an enclod space, such as a vehicle. The nsor compris: (a) a lar comprising a gain medium having two oppod facets within a lar resonator and functioning as an intracavity spectroscopic device having a first end and a cond end, the first end operatively associated with a partially reflecting (i.e., partially transmitting) surface; (b) a reflective or dispersive optical element (e.g., a mirror or a diffraction grating) operatively associated with the cond end to define a broadband wavelength lar resonator between the optical element and the first end and to thereby define an external cavity region between at least one facet of the gain medium and either the first end or the cond end or both ends; (c) the external cavity region being expod to air in the enclod space to enable any drugs or their metabolized by-product molecules to enter thereinto; (d) a detector spaced from the first end; (e) appropriate electronics for measuring and analyzing the detector signal; (f) a housing for containing at least the lar, the partially reflecting surface, and the optical element, the housing being configured to prevent escape of stray radiation into the enclod space

and to permit air from the enclod space to continuously circulate through the external cavity region
for analysis; and (g) means for driving the lar (e.g., electrical or optical). A method is provided for measuring concentration of drug vapors and their metabolized by- product vapors in the vehicle or other enclod space employing the on- board nsor. The method compris: (1) nsing any drugs and their metabolized by-product vapors in the enclod space by the on-board nsor; and (2) providing a signal indicative of prence of any drugs or metabolized vapors.
