Abstract

PURPOSE:To perform a good correction to improve the SN ratio and simplify the optical system by detecting a reference light and a signal light in the time division system for trace analysis and by operating them. CONSTITUTION:The light emitted from spectrum ligh source 1 is condensed by lens 10 and is focused onto atomizing equipment 12, where the magnetic field is applied, after becoming a plane rotately polarized light through light shielding plate 2 and polarizer 4. After incident onto spectroscope 16 through photo detector 14, the polarized light is detected by detector 17 and is supplied to time division circuit 18. Meanwhile, a reset signal is supplied to circuit 18, and a synchronizing signal dependent upon synchronizing stripe 3 is supplied circuit 18 also, and respective signals are stored. The rotately polarized light is picked up by signal light pick-up pulse 40 is signal position 36 dependent upon light shielding plate 2, and in this stage, the blank stored previously is subtracted, and the rotately polarized light is stored. The blank for reference light and the reference light are picked up by pulses 11 and 12 at points of positions 37 and 38 similarly. At this time, the output from circuit 18 is subjected to processings such an division in operation circuit 19 and is outputted.
