Automation of a Dobson ozone spectrophotometer
Abstract
The paper describes the principal electronic circuits of a Dobson ozone spectrophotometer which is automated in the sense that a servo system drives the calibrated disk that adjusts the optical wedge. Schematic diagrams of the circuits of the input amplifier, the level and polarity detector, the pulse generator and the power supply are shown along with a block diagram of the servo system performing automatic measurements. A list of interconnections and components is given.
