- W2940122433 abstract "The wide application of laser systems and the increase in the values of their energy characteristics, which may hazard to the health of staff and other people in the area of direct and reflected laser radiation, necessitates a permanent dosimetric monitoring in these areas. However, the methods of measuring the parameters of laser radiation at a given point in space to determine the degree of radiation safety for the human body, established in the standard DSTU EN 60825-1: 2016, are difficult to implement when using obsolete monitoring equipment. Therefore, the development of an automated method for determining the characteristics of a laser system and the rapid detection and determination of the direction and coordinates of laser radiation is relevant.
 The proposed method for automated determination of the laser system characteristics differs by applying an additional measurement channel with a photodetector, as in the main channel, and a compensated filter to ensure the difference of the readings in the channels, so that each difference of measured channel values corresponds to the one wavelength value. For the formation of a compensation filter with a constant spectral characteristic in the most demanded wavelength range from 0.4 microns to 1.1 microns are used by known methods of calculation and manufacturing. A combination of optical glass NSNU 13 and SZS-9 with varying thickness as a compensation filter is permitting measure of laser irradiation doze for radiation in this range with an error that does not exceed 15%.
 It is necessary to perform the tasks of quickly finding and estimating the angular coordinates of the laser sources for monitoring the parameters of laser radiation in the working area. Improving the design of the device for detecting and determining the angular coordinates of laser radiation is made by using an optical system that directs laser radiation to a photodetector of radiation and an information processing unit, in front of which a volume matted screen is installed so that the distance from the middle of the optical system to the nearest point of the screen is greater distance of the optical system. The photodetector matrix installed in the optical system focus is used as a photodetector of laser radiation.
 The application of spherical screens for direct laser radiation and cones for diffused and diffused reflected radiation is proposed for the effective and rapid determination of radiation corners in the working zone.
 Dosimeters with automated wavelength monitoring and detection and determination of the angular coordinates of laser radiation will facilitate and reduce the cost of conducting dosimetry monitoring." @default.
