Definitions
- the basic challenge today consists in bringing on the market a smart solution both on the sensor as on detecting device side.
- the sensing element needs to be included into the detection area in such a way that is able to sense the interesting propriety (gas, pH,%) while still able to be remotely activated and interrogated by the distant measurement unit.
- the present invention proposes a device for the interrogation of an optical sensing probe, comprising a detecting unit for detecting an optical wave emitted from said optical sensing probe.
- the said detecting unit comprises at least one CMOS and/or CCD imager or at least one CMOS and/or CCD sensor matrix.
- the device further comprises an illumination source of a wavelength corresponding to an absorption wave-length of said optical sensing probe.
- the device may comprise multiple illumination sources of different wavelengths, said wavelengths corresponding to an absorption wavelength of different optical sensing probes.
- the realization of the measurement device is based on an optical matrix sensor, which is able to demodulate the reflected modulated light in such a way that the phase shift can be extracted.
- the sensing part has to be realized with an electronic shutter or a mechanical shutter to split the modulation.
- the basic of the measurement is well known due to the principle of the time of flight (TOF) measurement using a phase shift measurement as described in T. Spirig et al., "The multitap lock-in CCD with offset subtraction", IEEE Transactions on electron devices, Vol. 44, No. 10, 1643-1647, October 1997 or R. Lange, P. Seitz, "Solid State Time-Of-Flight Range Camera", IEEE Journal of Quantum Electronics, 37 (2001) 390.
- the difference between the use of the technology for the distance measurement is that the measurement has to be done in a special range of wavelengths.
- the device can be used for remote temperature sensing, wherein said optical probe comprises a temperature sensitive, luminescent dye.
- the demodulation on the receiver side has the possibility to demodulate the incoming wave front r(t) depending on the emitted wave front S(t) .
