Abstract :
Passive millimeter-wave microscopy that enables imaging of the thermal radiation emitted from a viewed sample with a spatial resolution below the diffraction limit is investigated. Experiments performed at 50 GHz (λ = 6 mm) at various sample temperatures demonstrate the feasibility of our passive millimeter-wave microscope to image thermal radiation even in the low temperature range where passive imaging systems in the infrared region are ineffective.
