1. A non-touch thermometer to measure temperature, the non-touch thermometer comprising:

  • a microprocessor;

    a battery operably coupled to the microprocessor;

    a single button operably coupled to the microprocessor;

    a camera operably coupled to the microprocessor and providing at least two images to the microprocessor;

    a digital infrared sensor operably coupled to the microprocessor, the digital infrared sensor having ports that provide only digital readout; and

    a display device operably coupled to the microprocessor,wherein the microprocessor is operable to receive from the ports that provide only digital readout a digital signal that is representative of an infrared signal detected by the digital infrared sensor and the microprocessor is operable to determine the temperature from the digital signal that is representative of the infrared signal and the microprocessor including a pixel-examination-module configured to examine pixel values of the at least two images, a temporal-variation module to determine temporal variation of the pixel values between the at least two images being below a particular threshold, a signal processing module configured to amplify the temporal variation resulting in amplified temporal variation, and a visualizer to visualize a pattern of flow of blood in the amplified temporal variation in the at least two images.
