Abstract: An apparatus for measuring temperature of an object using compensation of board temperature may include an infrared light sensor module for providing output voltage due to the infrared light emitted by an object; a board temperature compensation module for compensating the provided output voltage to the output voltage at the reference configuration temperature of the board using a first function of output voltage to board temperature obtained at a reference configuration temperature of a blackbody; and a calculation module for obtaining the temperature of the object from the compensated output voltage using a second function of temperature of the blackbody to the output voltage obtained at a reference configuration temperature of the board.

Abstract: An apparatus for correcting a temperature of an object using a shutter may comprise a temperature measurement module for measuring the temperature of the object and a temperature of the shutter, a noise temperature calculation module for calculating the temperature due to noise using the measured temperature of the shutter, and a temperature correction module for correcting the temperature of the object by subtracting the calculated temperature due to noise from the measured temperature of the object.

Abstract: A temperature measuring device using a thermal imaging camera according to an embodiment of the present invention may comprise: a first operation module for obtaining, for the thermal imaging camera, a curve of temperature difference versus output code difference where the X axis represents the output code difference and the Y axis represents the temperature difference indicated by a plurality of measured values; a second operation module for obtaining a function of temperature difference versus output code difference, the function curve-fitted by using the curve of temperature difference versus output code difference; and a third operation module for measuring the temperature of an object by applying the curve-fitted function of temperature difference versus output code difference.

Abstract: A micro electro mechanical systems (MEMS) sensor packaging includes a first wafer having a readout integrated circuit (ROIC) formed thereon, a second wafer disposed corresponding to the first wafer and having a concave portion on one side thereof and a MEMS sensor prepared on the concave portion, joint solders formed along a surrounding of the MEMS sensor and sealing the MEMS sensor jointing the first and second wafers, and pad solders formed to electrically connect the ROIC circuit of the first wafer and the MEMS sensor of the second wafer. According to the present disclosure, in joining and packaging a wafer having the ROIC formed thereon and a wafer having the MEMS sensor formed thereon, the size of a package can be reduced and an electric signal can be stably provided by forming internally pad solders for electrically connecting the ROIC and the MEMS sensor.
