Publication number: 20110255093Abstract: In the interferometric system, the image plane is imaged by an output imaging setup via a transmission system of reflectors to the output plane and a reflection type diffraction grating is located in the image plane of an imaging setup of a reference branch. The transmission systems of reflectors are adjusted so that axes of both branches coincide at an entrance to the output plane and parallel with a normal line of the output plane, and an axial beam, diffracted by the reflection type diffraction grating at an angle ?, enters into the output plane at an angle ?, and the relation between angle ? and ? is sin(?)=sin(?)/m, where m is a magnification of the output imaging setup. The system enables the achievement of a holographic imaging of an object by low-coherence waves. Incoherent waves allow the imaging of objects immersed in scattering media.Type: ApplicationFiled: April 11, 2011Publication date: October 20, 2011Applicant: Vysoke uceni technicke v BrneInventors: Radim Chmelik, Pavel Kolman, Tomas Slaby, Martin Antos, Zbynek Dostal

Patent number: 4452196Abstract: Device for stopping a fuel injection internal combustion engine by turning a key in a stopping box into the STOP position. In hitherto known devices, when turning the key into the said position, current feeding the coil of the electromagnetic valve during the operation of the engine is cut off, and this valve is closed then by means of a prestressed spring. This makes impossible a free outflow of fuel leaving the reducing valve of a low pressure circuit of the injection device, and directs all fuel delivered by a delivery pump into a hydraulic member, the piston of which, by means of fuel pressure, shifts the control bar into the position STOP; in this way the engine is stopped. Such known arrangement requires too much power, since the coil of the electromagnetic valve is energized by current all during the operation of the engine. In accordance with the invention the coil of the electromagnetic valve is deenergized current during the operation of the engine.Type: GrantFiled: October 22, 1981Date of Patent: June 5, 1984Assignee: Vysoke uceni technicke v BrneInventor: Jaromir Indra
