12. An ocular surface temperature measurement apparatus comprising at least:
-
a supporting body for supporting a head; an infrared heat sensor disposed opposite to the supporting body such that the supporting body is positioned in a predetermined view field of the infrared heat sensor; a black body disposed on the supporting body and in the predetermined view field; a temperature sensor buried in and contacted with the black body, wherein the temperature sensor measures an actual black body temperature from the black body; and a working station electrically connected to the infrared heat sensor, the working station having at least a computing unit and a storage unit, wherein the infrared heat sensor detects a value of radiation emitted from the black body and the computing unit turn the value of radiation into a computed black body temperature according to a temperature rising curve; wherein a value of temperature shifting error is determined by subtracting the actual black body temperature from the computed black body temperature. - View Dependent Claims (13, 14)
