2.The process of increasing the magnitude of a variable quantity, especially the magnitude of voltage, power, or current, without altering any other quality.
3.Brillouin amplifier was numerically simulated by the theory model of transient stimulated Brillouin scattering including depleted pump. Energy extract efficiency. Stokes seed amplification factor and Stokes output pulse width versus encounter time in the Brillouin amplifier were given.
4.Based on the analysis of traditional methods and the laser scanning method to measure the curve of revolving shafts,thispaper puts forward a light-electronic system with a constant magnifying ower tsoachive an exact and accurate measurement of the revolving of revolving shafts.
5.The magnification of the microscope used for indentation measurement is 640.There are six loading stages which are 50, 100, 200, 300, 500 and 1000 grams.
6.The digital radiography system is a fiber-optics taper-coupled imaging system based on two CCD arrays.
7.YSX Series Operation Microscopes,using fibre-optic cable for coaxial illumination,have different working distance and illumination,have different working distance and magnification.They are featured for flexible handling and easy operation.They have found wide applications in ophthalmology,gynecology,ear-nose-throat,surgery and orthopedics etc.
8.The tendon contour of the flexible connector is imaged on CCD through illumination and a high magnifying lens. Then the actual dimension of the tendon thickness is obtained through image pre-processing,image segment,edge extracting and parameter calculation.
9.An electron tube used to amplify or generate ultrahigh frequency by means of velocity modulation.
10.The diagnostic accuracy of magnifying endoscopy is much better than routine endoscopy.
