Thermal Resolution & Validation

Mathematical modeling of a potential THIRFLIS sensor geometry (10-bit ADC) yields a thermal resolution of 9.4 µK per pixel in the sensor plane, when operating at a transformation layer temperature of T=306 K.

This graph is expected to be measured in the next months by the TECHNICAL RESEARCH CENTRE OF FINLAND (VTT) as validation of the THIRFLIS invention in the PHOTONHUB EUROPE Innovation Project No. 101016665, under supervision by VRIJE UNIVERSITEIT BRUSSEL (VUB).

Other THIRFLIS sensor geometries can be created where the transformation layer is cooled.
