Abstract: 【課題】受光素子により得られる信号を安定化することが可能な受光回路を提供する。 【解決手段】受光回路15は、受光素子12が接続される入力ノードN1における信号レベルと逆位相の出力信号SRを生成する信号生成回路21と、出力信号SRを入力ノードN1に帰還する帰還回路23と、を有する。逆位相の出力信号SRを受光素子12が接続される入力ノードN1に帰還することで、受光素子12に入射する光による信号レベルが帰還される出力信号SRによってキャンセルされる。このため、入力ノードN1の信号レベルを安定化する、つまり出力信号SRを安定化することができる。 【選択図】図2

Abstract: The present invention provides a photodetection apparatus having such an arrangement that when signals from the light receiving means in the photodetection device are sampled at a frequency substantially equal to the lowest frequency at which the source of pulse rays is lighted on, one of the noise signal I nc due to the pulsed illumination as from the fluorescent lamp and the normal output signal I nc from the laser beam necessarily presents for each of the sampling periods. In the preferred forms, output signal values sampled in the number of cycles corresponding to at least three times the sampling period are compared with each other. If it is judged that one output signal is larger than the other two output signals which are substantially equal to each other, it is determined that the one output signal is a normal output signal I sc from the laser beam. The one output signal is then taken for the subsequent signal processing step. In the other case, all the output signals are determined to be noise signals from disturbance rays as from the fluorescent lamp, including AC components and will not be taken for the subsequent signal processing step. In such a manner, any adverse affection due to the pulsed AC rays can be eliminated.

Abstract: A process for spectroscopically measuring the content of a component in a liquid mixture involves passing a single optical beam through the mixture without the use of a reference beam and measuring the intensitites of transmitted light in two different wavelength bands by means of two adjacent detectors responsive to light in the two wavelength bands respectively. The component being measured absorbs light within one of the wavelength bands. The ratio of the detector outputs can then be related to the component concentration. The principal use of the invention is for in-situ measurement of methanol in gasoline for motor vehicles.

Abstract: An optical measurement apparatus 10 primarily includes: a photon detection unit 12 for detecting incident photons, a time signal output unit 14 for outputting a time signal, and a storage unit 16 for storing the time signal outputted from the time signal output unit 14 when the photon detection unit 12 detects photons. The photon detection unit 12 includes a HPD 24 having a photocathode 24a and an APD 24b, a TZ amplifier 26, a peak holding circuit 28, and an A/D converter 30. The time signal output unit 14 includes a timer 32 and a counter 34. The storage unit 16 includes a comparator 36 and a memory 38. When photons impinge on the HPD 24, a trigger signal is outputted from the comparator 36, causing the photon-number outputted from the A/D converter 30 and the time data outputted from the counter 34 to be stored in the memory 38.
