Abstract: 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.

Abstract: The drift (°/h) for an interferometric fiber optic gyroscope (IFOG) means the variations on the voltage generated versus the zero angular (rotation) rate, while IFOG is not under influence of any angular rate effect. If the drift of an IFOG is predefined, the compensation of the drift can trivially be carried out by a subtraction process. However, with this invention, the necessity of the predefinition of the zero rotation rate voltage of the IFOG which belongs to the primary coil called “Gyro Coil” herein, is removed because the instantaneous variations on the zero rotation rate voltage of the IFOG can be monitored either periodically or whenever required with help of a secondary coil, called as “Monitor Coil”, which is able to be switched by a microcontroller controlled-MEMS fiber optic ON/OFF switches.

Abstract: 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.
