Abstract:
The present invention relates to the detection of optical sensors by means of measurement of information relative to the signal intensity and signal modulation phase shift. The proposed method employs the use of CMOS and/or CCD imager and illuminations with different wavelengths. The system is able realize a contactless measurement of a phase shift to curse on a gas concentration an distance.
