Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

Abstract: To enable measurement over a wide dynamic range from weak light quantity to strong light quantity in a light quantity detection device for detecting the light quantity, a detection signal from a photon counting light detector is A/D converted. When the A/D converted detection signal has a preset threshold value or more, the detection signal is transmitted as it is to a number-of-photons calculation circuit in a subsequent stage, and when the detection signal has the threshold value or less, threshold value processing for transmitting a preset reference value to the subsequent stage is performed. In the number-of-photons calculation circuit, the number of photons or the light quantity incident on the photon counting light detector is acquired from the dimension of an acquired detection signal waveform until the light quantity measurement ends.

Abstract: A method of determining lighting contributions of elements of a lighting component includes obtaining optical data representative of light output of the lighting component. Relative intensity data may be calculated from the optical data, and may indicate intensity differences in the light output of the lighting component as compared to that of a reference component. An optical property of an element of the lighting component is determined based on a comparison of the optical data with that of the reference component, where the reference component includes at least one reference element. Related systems and apparatus are also discussed.

Abstract: A display device is provided including a photosensor PS that detects the ambient light amount of a display area, a comparator that compares the output of the photosensor PS with a predetermined reference value, and a backlight controller that controls the amount of light supplied to the display area depending on a comparison result by the comparator, a switch SW for controlling application of a precharge potential is connected to a metal that exists near the light-receiving part of the photosensor PS with the intermediary of an insulating film. The embodiment apparently decreases the parasitic capacitance of the detection element to thereby suppress the influence of the parasitic capacitance of the detection element itself at the time of light amount detection.
