Digital holography of total internal reflection.

چکیده
We introduce a new microscopy technique termed total internal reflection holographic microscopy (TIRHM). Quantitative phase microscopy by digital holography is used to image the phase profile of light in total internal reflection, which is modulated by the materials present on or near the surface of internal reflection. The imaging characteristics are theoretically modeled and imaging capabilities are experimentally demonstrated.

Off-axis digital holography typically uses a beam splitter to combine reference and object waves at an angle matched to the sampling period of the sensor array. The beam splitter determines the thickness of the recording system. This paper describes and demonstrates a total internal reflection hologram that replaces the beam splitter and enables hologram recording over a large aperture with a t...
متن کاملTotal internal reflection holography for optical interconnections
Planar diffractive optical elements are well suited to fulfill the needs of optical interconnections. They are efficient and can serve as focusing elements, imaging elements, beam deflectors, and fan-out elements. Almost any shape of structure can be realized. This flexibility allows complex and compact interconnections. Two different types of diffractive optical elements exist: the holographic...
متن کاملAdvances in digital holography
Digital holography development has reached the level, which allows mass-manufacture of large size digital holograms – i-Lumograms, as well as manufacture of colour reflection holograms for security applications. Geola Digital also has proved that colour reflection holograms can be used as auto-stereoscopic projection displays for 3D gaming and home cinema applications. All that became possible ...
متن کاملA Thin Layer Imaging with the Total Internal Reflection Fluorescence Microscopy
Total internal reflection fluorescence microscopy (TIRFM) is an optical technique that allows imaging of a thin layer of the sample with a thickness of about 100-200 nm. It is used in science of cell biology to study cellular processes, especially near the membranes of living cells. This method is based on the total internal reflection phenomenon, where the evanescent wave is generated in the l...
متن کاملStochastic Digital Holography for Visualizing Strongly Refracting Transparent Objects
This paper presents a digital holographic method to visualize and measure refractive index variations, convection currents, or thermal gradients, occurring inside transparent but strongly refracting object. The proof of principle is provided through the visualization of refractive index variation inside a lighting ampoule. Comparison with transmission and reflection holography is also provided....
