The principle and structure of cyclic radial shearing interferometer are briefly discussed and the process of spatial phase modulation,Fourier transform method and wavefront reconstruction are analyzed.
The principle and structure of this system was described, the hardware and software design of wireless data transmission module based on CC1020 RF chip and PIC single chip computer were discussed in detail.
Take arsenic content measurement in product sample with Swiss ARL-9800 XP X-ray fluorescence spectrometer as an example,trouble occured for measuring is analyzed and energy profile graphics before and after spectrometer broke down are given. Working principle and structure of pulse height analyzer and scintillation counter are discussed. Causes of trouble are studied.
The principle and structure of this NSA are discussed, and its training algorithm is derived.
First, we explain the basic principle and structure of our robot, and show the specifications of our prototype robot and the result of some mechanical experiments.
This note presents the principle and structure of a tribological measure for floppy disks.
The underlying principle and structure of an automatized apparatus for identification mark sensing from the tubing string surface are considered.
An apparatus was designed to measure the temperature of the grnding spot in a grinding process. The dimension of the target area is about 0.4 × 0.6mm8 Its measuring temperature range is from 600℃ to 1700℃.Thus,this apparatus can be used for many other purposes.The principle and structure of this infrared thermometer were briefly stated. The situations of it's application in the grinding experiments were also mentioned.
This paper introduces an automatic infrared optometer, describes its basic principle and structure and the design of the optical system.
The article describes the applications,opreating principle and structure of the detector for optical point injector developed by us;and we hope that detector can be used to determine the optoelectronic characteristics of CCD image sensor.
