There is a technology called millimeter wave technology that is being experimented with that is longer wavelength than IR and can "see" through clouds and dense fog. It has not been commercialized at this time.
Yes, these types of IR cameras do not see any differently between Night and Daytime because they are using Long Wave Infrared detectors, not visible light. The image would appear about the same as in either condition.
I use my Forward Vision EVS both day and night. It does help alot in reduced visibility situations. Long wave IR does not see THROUGH a cloud but it does sense further INTO a cloud if there is something on the other side with a significant infrared signature. We usually acquire the runway environment 8-10 seconds earlier with the systems than we do with our eyes as a rule. Please ask if this answer leaves you with more questions!

Is there any system today that allows the pilot to see through dense fog ?

Nope, from what I know IR doesn't go through clouds. Not so dense smoke or ash yes, you can see through them.
