Description
Technical field
The technology belongs to hot spot homogenization field, and in particular to a kind of high power laser light hot spot uniforming device.
Background technology
Development in the heat protection design of manned spaceship and retrievable satellite etc., experiment and in-flight, and it is civilian
The industries such as fire-fighting, the energy, the building energy conservation in field, can use substantial amounts of radiant heat flux sensor.In order to ensure these are radiated
Heat flow transducer measurement value is accurate, it is necessary to set up corresponding hot-fluid standard and standard set-up, wherein topmost device is energy
It is enough that the stable, radiation source of uniform heat radiation energy is provided.
Generally, calibration radiant heat flux sensor uses calibrated radiation source method, be exactly using black matrix as radiant heat flux standard, its
Principle is, according to blackbody radiation law, radiant heat flow valuve to be traced to the source to the temperature value of radiation source by theoretical calculation.But, for
Measurement range is higher than 150W/cm2Big hot-fluid radiant heat flux sensor, limited (3500K or so) by the blackbody temperature upper limit,
More and more widely calibrated as heating flow source using superpower laser at present.But, laser output facula uniformity itself
It is poor, very big is influenceed on result in a calibration process.
The method that the utility model uses channel-type integrator, integrator, multiple reflections are introduced by high power laser light hot spot
After homogeneous, uniform light spots output is formed in integrator exit.By the research of the present apparatus, high hot-fluid radiation is applied it to
In the calibration of heat flow transducer, application effect is good.
Utility model content
The purpose of this utility model is：A kind of high power laser light hot spot uniforming device is provided, high power laser light is solved
Hot-fluid hot spot uniformity is poor, the problem of influenceing calibration result.
The technical solution of the utility model is as follows：A kind of high power laser light hot spot uniforming device, including integrator entrance,
A cuboid is collectively constituted between matrix A, matrix B, matrix C, matrix D, wherein matrix A, matrix B, matrix C, matrix D, it is long
Cube is located in connection adjusting bracket, and integrator entrance is provided with cuboid horizontal level；There is cooling between matrix C, matrix D
Water flow passage A, there is cooling water flow conduits C between matrix C, matrix A, has cooling water flow conduits B5 in matrix B, matrix D.
A cuboid is collectively constituted by screw between wherein matrix A, matrix B, matrix C, matrix D.
Matrix A, matrix B, matrix C, matrix D material are oxygen-free copper, outer surface nickel coating.
Remarkable result of the present utility model is：High power laser light hot spot is introduced into integrator, after multiple reflections are homogeneous,
Uniform light spots output is formed in integrator exit.By the research of the present apparatus, high hot-fluid radiant heat flux sensing is applied it to
In the calibration of device, application effect is good.
