Super resolution mid infrared imaging using photothermal microscopy
Mid infrared photothermal heterodyne imaging (MIR PHI) overcomes the diffraction limit of traditional MIR imaging and uses visible photodiodes as detectors. Our MIR PHI experiment achieved high sensitivity (S/N >100) sub diffraction limit spatial resolution and high acquisition speed. Sensitive, affordable and widely applicable, this technique is a promising imaging tool for biological systems.
