Reflections on immersion, death and renewal in film, literature and the arts are also extensive, often invoking the religious antecedents. Classic examples include Alice's transformation in the pool of tears in Lewis Carroll's Alice in Wonderland, and the swimming pool scene in Mike Nichol's film, The Graduate.
Methods of immersion or multiangular ellipsometry are applied to find the optical constants of the material with rough sample surface or presence of inhomogeneous media. New methodological approaches allow the use of reflection ellipsometry to measure physical and technical characteristics of gradient elements in case the surface layer of the ...
Merrill Swain is a Canadian applied linguist whose research has focused on second language acquisition (SLA). [1] Some of her most notable contributions to SLA research include the Output Hypothesis and her research related to immersion education. [2]
A total internal reflection fluorescence microscope (TIRFM) is a type of microscope with which a thin region of a specimen, usually less than 200 nanometers can be observed. TIRFM is an imaging modality which uses the excitation of fluorescent cells in a thin optical specimen section that is supported on a glass slide.
Parts of the Mirau interferometer: 1. Lens of the microscope, 2. Semitransparent mirror, 3. Object surface, 4. Reference mirror with reference beam, 5. First reflection of reference beam, 6. Third reflection of reference beam, 7. Reflection of object beam. A Mirau interferometer works on the same basic principle as a Michelson interferometer.
In the case of an interface with air (Z = 0), total reflection of the ultrasonic wave occurs; therefore, SAM is highly sensitive to any entrapped air in the sample under testing. [ 6 ] In order to enhance the insertion of the acoustic wave into the specimen both the acoustic transducer and the sample are immersed in a coupling media, typically ...
This index is determined by comparing two minerals directly, or comparing a mineral to a reference material such as Canada Balsam or an oil of known refractive index (oil immersion). When permanently mounted to a slide under a cover slip, the mounting medium is normally chosen to have the same refractive index as Canada Balsam ( n =1.55) to ...
Although similar physics guides the focusing process, [11] Scanning probe microscopes and scanning electron microscopes are not typically discussed in the context of optical sectioning as these microscopes only interact with the surface of the sample. Total internal reflection microscopy is a fluorescent microscopy technique, which ...
