Abstract
The paper describes the process of data obtaining for designing electro-optical sensors using a television aerosol particles image analyzer. Using simulation based on Mie theory, the process of calibration of simple electro-optical aerosol (dust) sensor is carried out. In the paper the main dependences for sensor calibration are shown. The proper calibration allows power saving by selection certain laser beam power level.
Highlights
In the development of optical-electronic sensors to control the concentration of industrial dust, there is the problem of their graduation for a specific type of dust
To obtain input data for computer modeling, it is proposed to use television measuring devices, whose work is based on image analysis of particles of industrial aerosol flowing through a measuring chamber [3, 4]
To obtain the model's input data, it is proposed to use a television measuring device, whose operation is based on television analysis of images of industrial aerosol particles flowing through a neasuremet chamber volume, which allows determining and storing in the computer the main aerosol parameters necessary for modeling, calculating and calibrating electro-optical sensors
Summary
In the development of optical-electronic sensors to control the concentration of industrial dust, there is the problem of their graduation for a specific type of dust. It is necessary to calibrate the sensors only on the site of their installation or in laboratory conditions on special stands. The currently existing mathematical models allow to design the parameters of such sensors with sufficient accuracy for practical implementation [1, 2, 5]. Existing television aerosol analyzers helps to obtain he missing data to make adequate models of electro-optical sensors. Obtaining adequate model of dust allows use optimal conditions for electro-optical sensors. It means that we can set the optimal level of laser beam power. It leads to common power saving in this sphere
