The invention discloses a dual-field thermal imager and a temperature measurement method thereof. The dual-field thermal imager includes a dual-field optical system, an infrared detector component, a stepper motor, and a core component. The dual-field optical system is connected with the stepper motor and the infrared detector component. The stepper motor is connected with the infrared detector component. The infrared detector component is connected with the core component. The dual-field optical system is used for focusing collected infrared radiation energy of a current field to the infrared detector component. The infrared detector component is used for converting the received infrared radiation energy into an electrical signal and sending the electrical signal to the core component, and receiving a focusing instruction sent by the core component to drive the stepper motor to move. The stepper motor is used for changing the focal length of the dual-field optical system. The core component is used for sending a focusing instruction and comparing a received electrical signal with a calibration temperature control table to get the temperature value of a measured object. Through the thermal imager and the temperature measurement method disclosed by the invention, the temperature of the current field can be accurately measured.
Description
technical field [0001] The invention relates to the field of thermal imagers, in particular to a dual-field thermal imager and a temperature measurement method. Background technique [0002] Because the thermal imager can detect the surface temperature of the measured object, has a certain penetrating ability, and can observe all-weather, it is widely used in national defense, industry, medical treatment, security and other fields. And because the dual-field optical system can achieve the purpose of focusing clearly in the large field of view and small field of view mode, the thermal imager installed with the dual-field optical system can conveniently realize long-distance and short-distance observation. However, most of the dual-field thermal imagers on the market are used for imaging and observation, and cannot measure temperature accurately. Contents of the invention [0003] The purpose of the present invention is to provide a dual-field thermal imager and a temperatu...
