Abstract

The present invention relates to a system, method and handheld device for measuring the internal temperature of a body by measuring thermal noise radiation at frequencies in the GHz range emitted from the body. The device comprises at least one receiver, a self contained power source, such as a battery and a front end comprising at least one reception circuit and at least one antenna, and optionally means for recording data. The total receiving cross section of the antenna area is less than 0,04m2, due to the longer wavelength in the GHz range and the deeper emission profile, measurement of the body temperature with the present invention does not depend on placing it over or near particular spots on the body. The device may be used with animals, foods and in many other contexts where the sub-surface temperature is of interest.
