    Abstract: PROBLEM TO BE SOLVED: To provide a technology for detecting a quantity of light, which enables measurement in a wide dynamic range from a quantity of weak light to a quantity of intense light in a light quantity detecting apparatus for detecting a quantity of light.SOLUTION: In the light quantity detecting apparatus, a detection signal of a photon count type photo-detector is A/D converted. A threshold-value processing is carried out such that if the A/D converted detection signal is equal to or higher than a preset threshold value, the detection signal is transmitted to the subsequent photon counting circuit as it is, and if the detection signal is equal to or lower than the threshold value, a preset reference value is transmitted to the subsequent circuit. In the photon counting circuit, the number of photons or the quantity of light that has entered the photon count type photo-detector is obtained from the area of the wave shape of the detection signal obtained until the measurement of the quantity of light finishes.

    Abstract: A system to detect or determine vehicle lamp performance and a method using the system is described. The system includes a first optical sensor having a field of view which includes the location of a vehicle lamp or into which light from a vehicle lamp is emitted, the optical sensor providing an output indicative of vehicle lamp performance; and a controller in communication with the first optical sensor to receive the output, the controller including at least one processor adapted to analyze the optical sensor output and provide a control output at least when the optical sensor output is indicative that the vehicle lamp performance is below a threshold.
