Description
Technical field
The invention belongs to laser energy meter collimation technique field, be specifically related to high-power halogen tungsten lamp residual amount of energy radiation efficiency measuring system and measuring method for a kind of laser energy meter calibrating.
Background technology
When utilizing high-power halogen tungsten lamp as calibration source, High Energy Laser Energy Meter to be calibrated, the electric flux part consuming on high-power halogen tungsten lamp converts light ray radiation to the absorption cavity of the High Energy Laser Energy Meter being calibrated, a part is trapped in the form with heat energy on the filament and lampshade of high-power halogen tungsten lamp in addition, and high-power halogen tungsten lamp can utilize photoelectric detector to measure at the actual gross energy to extraneous radiation of the power remove moment.After high-power halogen tungsten lamp dump, on halogen tungsten lamp remaining energy still can be constantly outside emittance, this part energy constantly increases along with the growth of time, finally levels off to a constant.Because the absorber of High Energy Laser Energy Meter just can reach thermal equilibrium in certain hour after high-power halogen tungsten lamp power remove, during this period of time the heat energy affecting on absorber due to the radiation of high-power halogen tungsten lamp residual amount of energy still can increase, therefore must measure the radiation of high-power halogen tungsten lamp residual amount of energy and account for the ratio that consumes gross energy, it is the radiation efficiency of residual amount of energy, in final calculating, just can this part energy be revised and be compensated like this, thereby improve calibration accuracy.
