Segmentation for Plate Microscopic Image

2008 International Conference on Computer Science and Software Engineering, 2008
With the rapid development of the Computer-To-Plate (CTP) technology, the detection and control of the dot area coverage on the plate become one of the key technologies to control quality during printing and copy processes. With regards to the characteristic of low contrast in plate image and fuzzy dot edge, the Fuzzy C-Means (FCM) clustering algorithm

Microscopic Imaging with Electrogenerated Chemiluminescence

Analytical Chemistry, 2001
The use of electrogenerated chemiluminescence (ECL) at microelectrodes as a light source for scanning optical microscopy is demonstrated. Cone-shaped microelectrodes were constructed by flame etching carbon fibers to a fine point. ECL generated in solution at such electrodes was forced to the apex of the conducting surface by using high-frequency (20 ...

Lensless stereo microscopic imaging

ACM SIGGRAPH 2007 emerging technologies, 2007
A simple inexpensive high-contrast stereo microscopic is constructed from a single video imager sensor. Two field-synchronous LEDs illuminate the subject creating disparity. The stereo microscope outputs standard field-sequential 3D video and is compatible with commercial head mounted displays and LCD shutter glasses.

Imaging with the tunneling and force microscopes

IEEE Proceedings on Micro Electro Mechanical Systems, An Investigation of Micro Structures, Sensors, Actuators, Machines and Robots., 1990
THE SCANNING TUNNELING MICROSCOPEThe STM is an instrument that is used for measuring surface structure. The new instrument was introduced when Rohrer, together with Binnig, discovered that a single atom at the end of a sharp tungsten needle could probe the electronic structure of smooth conducting surfaces.

Electron Microscopic Imaging of Integrin

2011
Rotary-shadowed samples often used for electron microscopy do not preserve native integrin conformations. Negatively stained integrins - or, more desirably, unstained integrins in a cryo-condition - are now being used with sophisticated imaging techniques.

An image intensifier for the electron microscope

Journal of Physics E: Scientific Instruments, 1968
An image intensifier system using a four-stage image intensifier optically coupled to a phosphor screen in the electron microscope is described. The system is shown to be limited by the quantum noise inherent in the electron image. The system can detect images down to 10 fA cm−2 which is at least an order of magnitude better than can be achieved by a ...

Contrast in the Electron Microscope Image

Nature, 1958
THE detail seen in a highly magnified electron micrograph is to-day limited more by a lack of contrast in the image than by any lack of resolution in the microscope, which is now usually capable of resolving objects at least as small as 15 A., that is, only a few atoms in diameter.

The Optics of Microscope Image Formation

2003
Although geometric optics gives a good understanding of how the microscope works, it fails in one critical area, which is explaining the origin of microscope resolution. To accomplish this, one must consider the microscope from the viewpoint of physical optics.
