LASER DOSIMETER Russian patent published in 2000 - IPC

FIELD: measurement of irradiancy. SUBSTANCE: laser dosimeter uses series- connected changeable photodetector, signal processing unit used at measurement of irradiancy, display, keyboard, and series - connected automatic range selection unit, analog-to-digital converter, microcontroller, control unit and driver amplifier unit; the output of the signal processing unit is connected to the automatic range selection unit, the second output of the automatic range selection unit is connected to the microcontroller, and its second input - to the driver amplifier unit, the second input of the analog-to-digital converter is connected to the microcontroller, the third input of the microcontroller is connected to the driver amplifier unit, its third output is connected to the display, and the third input - to the keyboard, the second output of the control unit is connected to the signal processing unit. The modification of the laser dosimeter designed for measurement of energy exposure is similar to the modification of the dosimeter for measurement of irradiancy; in the dosimeter for measurement of energy exposure the driver amplifier unit is coupled through its input and output to the signal processing unit. EFFECT: enhanced accuracy and speed of measurement of energy exposure to pulse radiation, irradiancy by continuous and microwave pulse-modulated radiation, frequency of radiation pulses, time of exposure, the laser operates in real time. 6 cl, 3 dwg
