摘要： Disclosed is an error correction unit enabling constant accurate measurement of a moving object by correcting an error attributable to a change in sensitivity of a thermal image sensor, a change in distance between a thermal image sensor and an object, or an ambient environment. Further disclosed is an object temperature detection device equipped with the same. The error correction unit includes a first arm member rotatably coupled to a thermal imaging camera unit, a heating element holder rotatably coupled to the first arm member, the heating element fixed to the heating element holder, and a temperature sensor configured to measure a temperature of the heating element. The heating element is positioned within an angle of view of the thermal imaging camera unit through rotational motion of the first arm member and the heating element holder. The temperature sensor measures the temperature of the heating element at a first time and a second time different from the first time so that the controller can use a temperature change value of the heating element. Data of the temperatures of the heating element, which are measured respectively at the first time and the second time, are transmitted to the controller.

摘要： An electronic device provided with a bacteria detection element and a bacteria detection sensor, and a method of detecting bacteria by using the same are proposed. The electronic device provided with the bacteria detection element and the bacteria detection sensor are disclosed such that a first semiconductor layer, a light absorption layer, and a second semiconductor layer are provided to have respective inclined surfaces in a mesa structure, the respective inclined surfaces are passivated by an oxide, and the light absorption layer is formed as a multi-layer. The electronic device having the bacteria detection sensor provides a function capable of detecting the bacteria and even sterilizing the detected bacteria. In particular, a UVC light source and a UVA light source are mounted on a single printed circuit board, whereby the electronic device may be produced in a small size and may reduce production costs.
