Optical olfactory sensor with holographic readout |
| abstract |
This invention relates to optical detection of vapors, in particular devices and methods for detection of vapor concentration and changes in vapor concentration using dynamic holography. The devices and methods employ a transducer which absorbs the vapor to be tested, thereby leading to a change in the transducer. The changes in the transducer cause a change in the optical path length of an image beam which is interacted with the transducer. Dynamic holography allows determination of the change in the dimensions and index of refraction of the transducer, and thus the change in the concentration of the vapor to be tested. The devices and methods of the invention are capable of testing a plurality of vapors by using a transducer array. |
