U of A engineering professor Dileepan Joseph and two graduate students produced a 3-D imaging system called Virtual Reflected-Light Microscopy. The technology consists of a regular optical microscope, a light source, a platform that moves the objects being photographed and software programs that extract shape and reflectance from images and transform this digital information into a 3-D image. To see the full effect on a computer screen viewers wear simple, paper framed 3-D glasses with red and cyan coloured lenses. Viewers also control a virtual light source, which they reposition using their web browser.
The test subjects used in the development of the VRLM were drilling core samples taken from beneath the floor of the Pacific Ocean. Joseph, Ph.D candidate Adam Harrison and master's student Cindy Wong produced 3-D images of ancient protozoa or microfossils that were mixed in with the sand and rock in the core samples.
Joseph says the VRLM gives geoscientists and computer programs in development much more information than simple images. The goal is to accelerate species identification of the tiny and numerous microfossils. Such identifications are used to date the rock from which the creatures are pulled. The microfossil species digitized by the U of A's VLRM prototype were found in rock known by geologists to be 60 million years old.
Geoscientists can use that kind of strata dating information in Earth sciences research and in the search for energy resources. The U of A researchers say there are multiple industrial and academic uses for their 3-D microscope technology.
The development of the VLRM technology is documented by the U of A researchers in the academic publication Journal of Microscopy.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
