    Abstract: A photometric device with a wide dynamic range. The photometric device includes a constant current generation circuit, a fixed clock signal generation circuit which generates a fixed clock signal having a fixed frequency, a photoelectric conversion element, a variable clock signal generation circuit and a digital signal generation circuit. The fixed clock signal generation circuit generates a fixed clock signal that oscillates at a fixed frequency, from constant current The variable clock signal generation circuit generates a variable clock signal that oscillates at a frequency proportional to the amount of photocurrent, from photocurrent generated in the photoelectric conversion element. The digital signal generation circuit sets a measurement period using the fixed clock signal, counts the number of pulses of the variable clock signal that oscillates for the measurement period, and outputs a digital signal including the count value as data.

    Abstract: A photometric device with a wide dynamic range. The photometric device includes a constant current generation circuit (104), a fixed clock signal generation circuit (105) which generates a fixed clock signal having a fixed frequency, a photoelectric conversion element (100), a variable clock signal generation circuit (101), and a digital signal generation circuit (103). The fixed clock signal generation circuit generates a fixed clock signal that oscillates at a fixed frequency, from constant current. The variable clock signal generation circuit generates a variable clock signal that oscillates at a frequency proportional to the amount of photocurrent, from photocurrent generated in the photoelectric conversion element. The digital signal generation circuit sets a measurement period using the fixed clock signal, counts the number of pulses of the variable clock signal that oscillates for the measurement period, and outputs a digital signal including the count value as data.

    Abstract: Die Erfindung befaßt sich mit der Verbesserung eines Ver­fahrens und einer Vorrichtung zur Messung der Strahlungs­absorption durch ein Medium mit dem Ziel der Erreichung und Einhaltung einer hohen Meßgenauigkeit geringer Drift über eine lange Standzeit ohne Notwendigkeit zum Austausch einzusetzender Komponenten in kürzeren Abständen. Zur Lösung der Aufgabe wird verfahrensmäßig vorgeschlagen, daß durch das Medium Strahlungs­blitze extrem kurzer Dauer hindurchgesandt und die empfangenen Strahlungsimpulse vor ihrer Weiterverarbeitung zeitlich gedehnt werden. Die Vorrichtung ist derart ausgestaltet, daß eine Strahlungsquelle eine Blitzlampe (11,12) aufweist und daß einem Detektor (13,14) ein die empfangenen Blitzimpulse zeitlich dehnender Verstärker (15,16) nachgeordnet ist.
