    • A light sensor comprises a first photodetector (52) sensitive in a first wavelength range; a second photodetector (60) sensitive in a second wavelength range different from the first wavelength range; and a processor for determining, using the output of the second photodetector, a correction to the output of the first photodetector for compensating the output of the first photodetector for a difference between the spectral response characteristic of the first photodetector and a reference spectral response characteristic. The processor is adapted to apply the correction to the output of the first photodetector. For example, the first photodetector (52) may be sensitive over the entire visible wavelength range and the second photodetector (60) may be sensitive in a blue wavelength range - this allows the output of the first photodetector to be corrected for an increased sensitivity in the blue wavelength range compared to the reference spectral response characteristic.The light sensor may be used in an Ambient Light Sensing (ALS) system, for example in the ALS of a display.

    • The averaged pulse energy (J) of a Pulsed Type Laser Source can be measured by several types of commercial laser energy meters, such as pyroelectric detector or thermopile sensor, the spectral responsivity and the time/frequency related response properties of which are compatible with those of the Pulsed Type Laser Source. These Commercial Laser Energy Meters, regardless of sensor/detector type, should be calibrated against the working standards calibrated in a national (or an international) traceability chain relying on primary standards on the highest level having the lowest uncertainty in realizations of the fundamental SI units. FCIS based-LEMCS designed in this invention accomplishes both of the above proficiencies of measuring the averaged pulse energy of the Pulsed Type Laser Source and calibrating the Commercial Laser Energy Meters, which are traceably to primary level standards. FCIS based-LEMCS contains an integrating sphere having a novel port and an interior design and a series of mechanical choppers having separate Duty Cycles, each of which is rotated by an electrical motor in FCIS based-LEMCS, used for generating a chopped type laser, called as Chopped Type Laser Source, in order to provide the reference and averaged pulse energy for traceable calibration of Commercial Laser Energy Meters. With this invention, in addition to generating the reference and averaged pulse energy to be used during the calibration of Commercial Laser Energy Meters to be performed by means of FCIS based-LEMCS, the peak pulse energies of the Pulsed Type Laser Source and the Chopped Type Laser Source, which is a strict part of FCIS based-LEMS and which is used for producing the reference averaged pulse energy in the calibration of Commercial Laser Energy Meters, are also measured by FCIS based-LEMCS, traceable to Electrical Substitution Cryogenic Radiometer (ESCR) in primary optical watt scale (W), to 133 Cs (or 87 Rb) Atomic Frequency Standard in time scale t (s), and to direct current unit (A) realized with Quantum Hall - primary resistance standard (ohm) and DC Josephson primary voltage standard (V). With this configuration presented as a preferred embodiment, the averaged pulse energy measurements are performed and achieved for a range extending from 16.5 p J to 100 mJ.
