Image-based Surface Measurement
Recent new developments in the electronics have leaded to the manufacturing of new high-resolution digital sensors (up to 39 mega pixel) for terrestrial cameras. These technological innovations, together with new processing algorithms of image matching, allow to obtain image-based surface models in an almost automatic way with an accuracy and a detail level that can be surely compared with the ...
متن کاملSingle-image far-field subdiffraction limit imaging with axicon.
This Letter presents a technique for subdiffraction limit imaging termed Bessel beam microscopy (BBM). By placing a lens in series with an axicon in the optical path of a microscope, the diffraction-limited resolution of the base microscope is improved by one third. This improvement is demonstrated experimentally by resolving individual subdiffraction limit fluorescent beads in a close-pack arr...
متن کاملSingle Image Appearance Measurement
Creating realistic renderings in computer graphics depends on having knowledge of the reflectance properties of materials in the scene. For opaque materials the bi-directional reflectance function (BRDF) captures these properties. Full BRDFs can be measured using highlyaccurate gonioreflectometers or more recently with techniques using digital cameras. These approaches sample the BRDF either de...
متن کاملMicrofluidic sensor for dynamic surface tension measurement.
A novel microfluidic sensor for measuring dynamic gas-liquid interfacial tension is reported. The device consists of a microfluidic chip with a microchannel network and an optical detection system. The sample is introduced into a main channel, while air is injected through a T-junction. Owing to the fixed flow rate ratio used for the sensor, surface tension is the only parameter determining bub...
متن کاملPhotoacoustic imaging velocimetry for flow-field measurement.
We present the photoacoustic imaging velocimetry (PAIV) method for flow-field measurement based on a linear transducer array. The PAIV method is realized by using a Q-switched pulsed laser, a linear transducer array, a parallel data-acquisition equipment and dynamic focusing reconstruction. Tracers used to track liquid flow field were real-timely detected, two-dimensional (2-D) flow visualizati...
