Abstract
We present a differential Near-field Scanning Optical Microscope (NSOM) operating with subwavelength resolution in the THz spectral region. The system, which employs a quantum cascade laser emitting at λ =105 μm as source, has been been tested on metal and graphite objects, with a resolution of ~ λ/10.
