Interference Microscopy

 

a method of investigating the structure of various, mainly biological, objects and of measuring their dry weight, thickness, and refractive index. Based on light interference, interference microscopy makes use of the interference microscope.

White-light interference microscopy, which is the basis for many products from Zygo Corp., Middlefield, Conn., is useful for fast, non-contact analysis of surface height structures, and has become a powerful alternative to ellipsometry, atomic force microscopy, and electron microscopy.
Nevertheless, interference microscopy is best suited to measuring small height differences within a limited range.
Thus, a nondestructive, noninvasive tool such as interference microscopy or confocal microscopy is more suitable to monitor physical changes throughout the entire degradation process.
The techniques used to make measurements in an attempt to determine the TPO surface morphology have included X-ray microfocus fluoroscopy [2], visible-light differential interference microscopy [2] and photoacoustic Fourier transform infrared spectroscopy [5].
Formation of two spherical nuage/ Balbiani bodies along the long axis of previtellogenic oocytes in Acheta domestica was demonstrated by differential interference microscopy. Both form adjacent to and on opposite sides of the germinal vesicle, the anterior body earliest.
We used Nomarski interference filters on a Leica microscope to perform differential interference microscopy at a magnification of 500X.
Diverse observation: The episcopic illumination models of the ECLIPSE LV-N series allow for bright-field, dark-field, simple polarization, differential interference epi-fluorescence, and two-beam interference microscopy.
The only other technique capable of phase measurement is interference microscopy. However, QPm does not require the additional information that interference microscopy does in order to unwrap the wavefront information.
