Abstract
Exemplary systems for detecting water include: a light source positioned to transmit thermal radiation through a sample; a lens assembly positioned to: receive the thermal radiation transmitted through the sample; and focus the transmitted thermal radiation onto a filter positioned between the lens assembly and a detector; and a cooling subsystem for cooling the filter and the detector to a temperature below that of the sample. Methods for detecting presence of water in a sample are also disclosed.
Claims20
A system, comprising:
- a light source positioned to transmit thermal radiation through a sample;
- a lens assembly positioned to:
- receive the thermal radiation transmitted through the sample;
- and
- focus the transmitted thermal radiation onto a filter positioned between the lens assembly and a detector;
- and
- a cooling subsystem thermally coupled to at least the filter and the detector to cool the filter and the detector to a temperature below a temperature of the sample.
