Laser stroboscopic photography. Technique for cell orientation studies in flow.

Tissue blood flow measurement by laser Doppler technique

  Measurement of blood flow and the effects of different factors on tissue blood flow are important fields of research in physiology and pharmacology. So far, different methods have been innovated, using laser light is the Last one. In this article history, principles and specifications of laser technique along with its advantages and disadvantages ( in comparison with other methods) are revie...

Placing photography in memory studies

A commonsensical way of relating photography to memory is one that assumes that photographs in some way “preserve” or “capture” memories for posterity. A photograph album with the inscription “Treasured Memories” on the cover, or a Kodak ad promoting the camera “as a means of keeping green the Christmas memories” (Paster 1992: 138), are perhaps the most quotidian instantiations of this assumpti...

Laser speckle photography for surface tampering detection Citation

It is often desirable to detect whether a surface has been touched, even when the changes made to that surface are too subtle to see in a pair of before and after images. To address this challenge, we introduce a new imaging technique that combines computational photography and laser speckle imaging. Without requiring controlled laboratory conditions, our method is able to detect surface change...
