Interferometric microscopy or Imaging interferometric microscopy is the concept of microscopy which is related to holography, synthetic-aperture imaging, and off-axis-dark-field illumination techniques. Interferometric microscopy allows enhancement of resolution of optical microscopy due to interferometric (holographic) registration of several partial images (amplitude and phase) and the numerical combining. ==Combining of partial images== In interferometric microscopy, the image of a micro-object is synthesized numerically as a coherent combination of partial images with registered amplitude and phase 〔 For registration of partial images, the conventional holographic set-up is used, with the reference wave, which is usual for the optical holography. The multiple exposition allows the numerical emulation of a large Numerical Aperture objective, at moderate values of the Numerical Aperture of the objective used to register partial images.〔 Similar techniques allows scanning and precise detection of small particles.〔 〕 As the combined image keeps both amplitude and phase information, the interferometric microscopy can be especially efficient for the phase objects,〔 〕 allowing detection of light variations of index of refraction, which cause the phase shift or the light passing through for a small fraction of a radian. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「interferometric microscopy」の詳細全文を読む スポンサード リンク
