Abstract

PURPOSE:To avoid the failure due to drive system and to enable the measurement with high accuracy, by intermittent laser current with a given period to detect laser light power and amplifying the output signal of infrared ray detector with amplifier. CONSTITUTION:The laser light emitted from the wave length variable laser 1 is made parallel with the convex lens 2, the path is bent by 90 deg. at the flat mirror 3 and radiated outside the analyzer A. The current to excite the laser 1 is fed from the laser current source 4 controlled with the program by the current limit circuit 5. The laser light emitted externally is reflected at the bent reflection mirror 7 and again returns to the unit A. The laser light returned is converged with the concave mirror 8, and again into parallel light at another concave mirror 9, and image is focussed on the light reception plane of the infrared ray detector 21 at the final concave mirror 10. The output signal of the detector 12 is in DC amplification at the DC amplifier 13 and delivered to the signal processing circuit 14. Thus, the measurement with high accuracy can be made.
