The basic measurement principle uses interferometric recording of light waves reflected from component surfaces. By clever use of several lasers with different wavelengths, also macroscopic objects can be measured with sub-micrometer accuracy. Scientists at Fraunhofer Institute for Physical Measurement ...
The principle of thelight microscopeis based upon the image obtained after a light is crossed through a thin sample and submitted to a system of lenses. So, a light microscope consists of an optical system with a tube with lenses on each tip: the ‘ocular’ near the eye and the ‘object...
the same chip to normalize the transmission spectra of the device. The designs of mode (de)multiplexers are based on traditional ADCs structures. Figure2dshows the scanning electron microscope (SEM) image of a TE0-TE2metamaterial BB. Both the simulated and measured mode manipulation efficiency are...

thus are almost transparent in a conventional bright field microscope. A number of approaches for increasing contrast have been developed, among which staining and fluorescence are possibly the most far-reaching development since the inception of the light microscope [Fig.1]. In the twentieth century...
The ability of the microscope to align via phase modulation alone also ensures its accuracy for multicolor 3D imaging and makes the microscope reliable and easy to operate. Here we describe the working principle and design of the microscope. We demonstrate its utility by imaging various cleared ...

Many polarisation techniques have been harnessed for decades in biological and clinical research, each based upon measurement of the vectorial properties of light or the vectorial transformations imposed on light by objects. Various advanced vector measu
Based on this principle, the prototype ultraviolet microscope was constructed by Köhler7 in 1904, while X-rays8,9 were later introduced into the micro-imaging system. The natural progression of this work was the realization of electron microscopy,10 where electrons with a critically shorter de ...
