Abstract: A radiometer for a microwave receiver according to an embodiment of the present invention comprises: an antenna line through which radiation power corresponding to the temperature of a probe is received from an antenna; a first reference rod having a first reference temperature fixed in advance; a second reference rod having a second reference temperature fixed in advance; a first microwave switch for selectively switching the antenna line, the first reference load, and the second reference load; a second microwave switch switched with the same clock as the first microwave switch; a demodulator for multiplying a signal output from the second microwave switch by a predetermined gain value and outputting same; an integrator for integrating the signal output from the demodulator; and a controller for measuring the temperature of the probe on the basis of a signal output from the integrator.

Abstract: Provided are a radio frequency (RF) receiver module for sensing core body temperature and an RF microwave core body thermometer system having the same. The RF receiver module for sensing core body temperature and the RF microwave core body thermometer having the same include: an RF contact-type patch antenna attached to a body part to sense the core body temperature; an RF receiver circuit unit attached to the body part to receive any one RF frequency signal within an RF frequency range of 1 to 10 GHz except for 1.4 GHz, 1.6 GHz, 1.7 GHz, 2.6 GHz and 2.7 GHz through the RF contact-type patch antenna for sensing core body temperature; and an interface circuit unit for connecting the RF receiver circuit unit to a control unit of a microprocessor control unit.

Abstract: Disclosed is a portable device for measuring temperature with infrared array sensor. This portable device includes: an infrared array sensor module for taking temperature values in a unit of pixel and including a plurality of infrared sensors arranged in an array of pixels; a controller for calculating a resultant temperature value of a subject with reference to the temperature values taken each by the sensors; a display for expressing the resultant temperature value calculated by the controller; and a view finder with an indicator defining a target point to be measured for temperature and having a profile corresponding to the whole or a local shape of the subject. The view finder is formed of a transparent plate on which the subject's shape is reflected. The transparent plate is formed of: a notch representing the indicator; and a lens at least provided in the indicator.

Abstract: Disclosed is a device and method for measuring temperature with infrared array sensor. This device includes: an infrared array sensor module to take thermal picture information of a subject, including a plurality of infrared sensors arranged in an array of pixels; an on-screen display module to generate an indicator having a profile corresponding to an entire or local shape of the subject and defining a target point to be measured for temperature; a display module to express the indicator and the thermal picture information; and a controller to enable the infrared array sensor module to measure the subject's temperature if the target point displayed by the thermal picture information overlaps with the indicator while the thermal picture information is expressed on the display module along with the indicator.
