Holographie en infrarouge sur de minces couches d'huile
Abstract:
Oil films of approximately 1-microm thickness on glass plates are used as a holographic recording medium at a 10.6-microm wavelength. This dynamic recording medium (on which the recording is not permanent) shows diffraction efficiencies up to 20% when reconstructing at 632.8 nm, the spatial frequency at the recording being as high as ~50 cycles/mm. Furthermore, the response time of these oil films when recording ir can be as small as 2 msec so that ir holography of moving objects is possible in real time.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
