50 results about "Soft focus" patented technology

In photography, soft focus is a lens flaw, in which the lens forms images that are blurred due to spherical aberration. A soft focus lens deliberately introduces spherical aberration in order to give the appearance of blurring the image while retaining sharp edges; it is not the same as an out-of-focus image, and the effect cannot be achieved simply by defocusing a sharp lens. Soft focus is also the name of the style of photograph produced by such a lens.

Main electrode probe based on soft focus array side direction

The invention relates to a main electrode probe based on a soft focus array side direction. The main electrode probe comprises a metal mandrel, an upper connector, a lower connector, an upper pressure bearing connector and a lower pressure bearing connector. The two ends of the metal mandrel are fixedly connected with the upper connector and the lower connector through pins. A front amplifying module is arranged on the outer circle surface of the front end of the metal mandrel. The outer circle surface of the metal mandrel is sleeved with a mandrel insulating sleeve. A contact spring is fixed to a fixing groove of the mandrel insulating sleeve. Two wire passing grooves are provided with a transmitting wire bundle and a receiving wire bundle. One end of the transmitting wire bundle and one end of the receiving wire bundle are connected with the contact spring in a soldering manner, and the other end of the transmitting wire bundle and the other end of the receiving wire bundle are connected with the upper pressure bearing connector and the lower pressure bearing connector in a soldering manner. A plurality of electrodes and a plurality of isolating sleeves are alternately connected at intervals and are sequentially arranged into the mandrel insulating sleeve, and the electrodes are in pressing contact with the contact spring on the mandrel insulating sleeve. By means of the main electrode probe based on the soft focus array side direction, a plurality of resistivity change curves from a formation invasion zone to an undisturbed formation can be obtained under high temperature and high pressure.
