6. A non-contact condensation detecting apparatus, comprising:
a measurement unit disposed at two or more locations, near an object surface and distant from the object surface, the measurement unit including
a temperature/humidity sensor configured to measure temperature and humidity of gas of an atmosphere surrounding the object surface, and
a flowsensor configured to measure one of a flow direction and flow velocity of the gas of the atmosphere surrounding the object surface; and
a processing unit configured to
determine distribution of the atmosphere with respect to the object surface and a transportation state of the atmosphere based on measurement results of the temperature/humidity sensor and the flowsensor, and
detect a behavior of the gas adhering and aggregating onto the object surface, and a behavior of aggregated liquid transpiring from the object surface.
