    • 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 133Cs (or 87Rb) 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.

    • The drift (°/h) for an interferometric fiber optic gyroscope (IFOG) means the variations on the voltage generated versus the zero angular (rotation) rate, whilst 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. The new configuration of IFOG, to be referred as Dynamical Drift Monitoring-Interferometric Fiber Optic Gyroscope (DDM-IFOG) and the new method presented and implemented in this invention are valid for IFOG having open-loop and closed-loop schemes by engaging the voltage of zeroing the total phase (Feedback Phase Ø plus Sagnac Phase Shift) in the sensing coil instead of directly using the voltage of the demodulation circuit induced by the Sagnac Phase Shift (SPS).
    • 用于干涉光纤陀螺仪(IFOG)的漂移(°/ h)表示产生的电压与零角度(旋转)速率的变化,而IFOG不受任何角速率影响。 如果预定义了IFOG的漂移,则漂移的补偿可以通过减法处理进行。 然而,利用本发明,由于IFOG的零旋转速率电压的瞬时变化可以是由IFOG的零旋转速率电压的瞬时变化,因此除去属于这里称为“陀螺线圈”的初级线圈的IFOG的零旋转速率电压的必要性 通过被称为“监视器线圈”的次级线圈,可以通过微控制器控制的MEMS光纤开/关开关来周期性地或需要时进行监控。 IFOG的新配置,被称为动态漂移监测 - 干涉光纤陀螺仪(DDM-IFOG)和本发明中提出和实现的新方法对于具有开环和闭环方案的IFOG是有效的,通过接合电压 而不是直接使用由Sagnac Phase Shift(SPS)引起的解调电路的电压,使感测线圈中的总相位(反馈相位Ø加Sagnac相移)归零。

    • Segmentation of certain regions defined on a firearm cartridge case for successful automatic matching of cartridge cases after a cartridge is fired, on the basis of the marks left on the cartridge cases fired. Disclosed is a method for segmentation of a cartridge case base by using surface height matrix information comprising: detecting the center of the cartridge case base; according to this center, obtaining the polar height matrix by subjecting the surface height matrix to polar transformation; acquiring a one-dimensional signal, “Average Height Signal on the Basis of Radius” (AHSBR), by calculation of the mean value on the radius axis applied on the polar height matrix; determining regions similar to circle signal models on the AHSBR and detecting circles; determining the firing pin mark region by threshold processing of the primer region surface height matrix. Letters on the cartridge case base are detected by using slope matrices.
