Open the CIPO recordAbstract From the Canadian patent
The invention relates to a detection system according to which one or more , light sources are switched on at defined time intervals using a control unit. , The light emitted from the operational light sources is fed via the optical fibre that is assigned to the respective light source to a solid body sensor that is allocated to the light source. In said sensor the optical signal is , modified according to the temperature. The modified optical signal is fed via optical fibres to an optical mixer, in which the modified optical signals of all solid body sensors are combined and the resultant optical signal is fed from the mixer to an optical detection system where the spectral , …

Why it's free to use
- Filed May 23, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 23, 2021.
