Abstract: An integrating photometer for measuring total exposures to ultraviolet radiation. The circuit for the photometer includes a threshold limiter to suppress operation of the integrator until the illumination level exceeds a predetermined threshold. A power saving circuit turns the photometer off when no illumination is received during a predetermined time interval.

Abstract: The following steps are performed in connection with a photodiode circuit: a) resetting the photodiode circuit; b) determining when a photodiode voltage changes in response to illumination to reach a threshold; and c) updating a counter in response to the determination in step b). The steps a) to c) are repeated until an end of a measurement period is reached. The value of the counter at the end of the measurement period is then output to indicate an intensity of the illumination.

Abstract: A photometer in which a measuring phase, a reference phase and a dark phase are produced by means of a chopper. These phases are staggered in time, so that a single detector can be provided for all phases. In the photometer the object to be measured is situated between two light conductors, the one light conductor leading to the detector and the other light conductor leading to the chopper input. The chopper output is carried by an additional light conductor to the detector.

Abstract: The invention relates to measuring illuminating power of light incident on a light sensor without an outside power supply. The light is converted conventionally to a pulse train, the frequency of which varies as the illuminating power. During conversion the incident light illuminates a series connection (2) of a plurality of photo diodes, which thus generate a current. This is utilized as a power source for the converter and also as electrical input quantity for the conversion itself. The pulse train generated by the converter comprises light pulses, the frequency of which is detected at the converter or at the other end of an optical fibre (7) coupled to it.
Abstract translation: 本发明涉及在没有外部电源的情况下测量入射到光传感器上的光的照明功率。 光被传统地转换成脉冲串，其频率作为照明功率而变化。 在转换期间，入射光照亮多个光电二极管的串联（2），从而产生电流。 这被用作转换器的电源，也用作转换本身的电输入量。 由转换器产生的脉冲串包括光脉冲，其频率在耦合到其的光纤（7）的转换器或另一端检测。
