An evanescent field arising from photons tunneling through a total internal reflection boundary is employed as a high vertical resolution (less than 1 nm, detector-limited) height transducer which maps sample microtopography into a grayscale imagespace. A video densitometer and xyz oscilloscope restore the grayscale image to a 3D topographic image; restoration and viewing perspective manipulation are real-time. Depth of field is about 1 µm and lateral resolution is typical to an oil immersion… 

Photon Tunneling Microscopy of Polymeric Surfaces

The use of photon tunneling microscopy to study single crystals of polyethylene and processes such as latex film formation and the evolution of polystyrene topography while dewetting above the glass transition temperature are described.

Photon Tunneling Microscopy of Polymers

The photon tunneling microscope (PTM) can image polymer surface morphology with vertical resolution below a nanometer and lateral resolution of 0.10 μm. PTM produces visual, whole-field tunneling

DEVELOPMENT OF A NEW OPTICAL TUNNELING MICROSCOPE

An optical tunneling microscope with subnanometric resolution is described. This photon tunneling instrument is extremely sensitive to surface profile along the longitudinal axis, while its lateral

SCANNING TUNNELING OPTICAL MICROSCOPY

For overpassing the classical limit of resolution in optical microscopy, it is necessary to detect the light diffracted from small objects in the near field and not in the far field as in classical

Spectroscopic imaging in the near field with an apertureless solid immersion lens microscope

To achieve high lateral resolution in microscopy, we exploit the localized electromagnetic field of a Solid Immersion Lens (SIL). The lens is mounted on a cantilever of a Scanning Probe Microscope

Application of Solid Immersion Lens to Submicron Resolution Imaging of Nano-Scale Quantum Wells

We have discussed the resolution of submicron photoluminescence (PL) imaging using a solid immersion lens (SIL), which collects an evanescent light field. We apply the SIL microscope to measure PL

Evanescent-field scanning microscope with fourier-transform infrared spectrometer

An evanescent-field scanning microscope for infrared microanalysis has been developed. This microscope uses an evanescent field produced by total internal reflection with a high refractive index

Near-Field Microscope Probes Utilizing Surface Plasmon Polaritons

The near-field microscope is characterized by its super-resolution capability. It exceeds the classical limit of spatial resolution of the light microscope due to the wave nature of photons or the

New form of scanning optical microscopy.

The exponential decay of the evanescent field due to the total internal reflection (TIR) of a light beam in a prism is used to advantage in a new form of scanning optical microscope, the photon

General principles of scanning tunneling optical microscopy.

A homogeneous propagating wave falling onto submicrometer objects is partially diffracted into evanescent waves that can be converted into homogeneous ones and made detection possible by the use of a scattering probe of subwavelength size.

Scanning near‐field optical microscopy (SNOM)

SNOM is a non‐contact stylus microscopy analogous to STM. Optical near‐field interaction is used to sense approach and optical properties on the nanometre scale (≅1 nm normal, 20–50 nm lateral). SNOM

The Tunneling Microscope: A New Look at the Atomic World

A new instrument called the tunneling microscope has recently been developed that is capable of generating real-space images of surfaces showing atomic structure. These images offer a new view of

Optical Systems for Observing Surface Topography by Frustrated Total Internal Reflection and by Interference

If surface topography is examined by frustrated total internal reflection, light leaves the object plane in a direction displaced from the normal by at least the critical angle. If the optical system

Frustrated total internal reflection: A demonstration and review

Frustrated total internal reflection (FTIR) has been studied since the time of Newton and Fresnel. We review its history and applications in modern optics. A simple theoretical description of the

Frustrated Total Internal Reflection and Application of Its Principle to Laser Cavity Design

A general treatment of the phenomenon of frustrated total internal reflection is presented and numerical results are given which are related to cavity resonator design parameters. A minimum loss,
