Abstract: PURPOSE: To decrease yield of noises due to phase deviation caused by rapid absorption and the like, by detecting a sample light component and a reference light component having different frequencies, and performing specified electric processing.
CONSTITUTION: Light emitted from a light source becomes sample luminous flux 13 with a frequency (f) and reference luminous flux with a frequency 2f through plane mirrors 2 and 3, concave mirrors 4 and 5, and choppers 17 and 18. Both luminous fluxes 13 and 14 pass a sample cell 15 and a reference cell 15, respectively, are guided to a monochrometer 11 through plane mirrors 6 and 7, a half mirror 8, a concave mirror 9, and a plane mirror 10, and are inputted to a detector 12. Its output is sent to an amplifier 19, filters 20 and 21, and rectifiers 22 and 23, and rectified by the aid of synchronized wave signal from a synchronized waveform device 24, which is synchronized with the choppers 17 and 18. The sample component output S' is sent to a differential amplifier 26 directly and through a differential circuit 25. A sample signal S, from which noises are removed, is sent to a divider 27. The ratio between the signal S and a reference signal R from the rectifier 22 is obtained and recorded in a recorder 28. Thus the generation of the noises can be decreased.

A second sector 9 has a pervious part and a reflective part each having a specific pattern and the reference light beam 14 permeated through the second sector 9 and the sample light beam 15 reflected by the second sector 9 mutually passes a monochromator 12 to be incident to a detector 13. The first sector 3 and the second sector 9 are synchronously rotated at a rotation ratio of 1:4 and the ratio of sample beam/reference beam is directly calculated from the output of the detector 13 by a frequency component detecting system.

Abstract: PURPOSE:To enable the calibration and inspection of equipment based on the intensity of a sample light at absolute 0 by getting the order and combination of taking out the sample light, reference light and a dark specified. CONSTITUTION:The output of a detector 8 such as thermocouple is applied to a signal component separation circuit 11 as amplified and separated into a frequency (f) corresponding to one cycle of an optical path switching means and a frequency 2f doubling it with BPFs 12 and 13. A signal proportional to the intensity I of sample lights and a signal proportional to the intensity I0 of reference light are obtained from a component synchronous rectification circuits 15 and 16 and applied to a ratio computation circuit 19, which outputs a signal corresponding to I/I0. The component of a fundamental frequency (f) is a function of the sample light I alone, hence irrelevant to the intensity I0 of the reference light. In other words, when the intensity I of the sample light is 0, the component of the fundamental frequency (f) is 0. Therefore, the sample light optical path is intercepted to turn the intensity I of the sample light to absolute 0. This enable the calibration and inspection of equipment based on it thereby facilitating the adjustment and inspection while improving the accuracy.
