The temperature controller is fixed on background thermal insulation board middle, for adjustment control grey body heater temperature, the thermometric plate
It is fixed at temperature controller surface cavities, makes temperature uniform and stable, the grey body heater is placed on thermometric plate, described
Digital thermometer is arranged on outer side surface, and the contact temperature probe placement is in the drilling of thermometric plate, the light harvesting
Luminaire, which buckles, to be installed on above background thermal insulation board, is installed in the round aperture of collection light illuminator, is treated built in the collimator
Survey infrared imaging device alignment collimator.The surface of the grey body heater is provided with array groove with angle, and the depth of groove is not
Together.
Furtherly, the light illuminator that integrates is a semi-round ball using grey body heater center as the center of circle, in semicircle
A circular apertures are cut out at the top of ball, the collection light illuminator uses the metal with heat conductivility to make, can prevented infrared
Line penetrates, and its arcuate structure causes the infrared ray of reflection to return at grey body heater center.
Furtherly, the round aperture that its semi-round ball of collection light illuminator top is cut out is installed on built in the collimator
Interior, the collimator is cylindrical structure, and outer surface is brought into close contact with the circular apertures cut out at the top of collection light illuminator semi-round ball,
So that into infrared imaging device the lucky vertical irradiation of infrared ray at grey body heater center.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is surveyed by the minimum resolvable temperature difference of design
Trial assembly is put, and structure is single, easy to use, is easy to carry, and can be produced by the tilt angles for changing grey body heater array groove
The raw different temperature difference, the test to infrared imaging device minimum resolvable temperature difference parameter can be realized independently of environment temperature, is changed
Grey body heater, it is possible to achieve the quick test in scene of different infrared imaging device minimum resolvable temperature difference parameters.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1, Fig. 1 is the structural representation of the present invention.
For embodiments of the invention by taking thermal infrared imager as an example, the embodiment includes shell 1, background thermal insulation board 2, temperature control
Device 3, thermometric plate 4, grey body heater 5, digital thermometer 6, contact temperature probe 7, collect light illuminator 8, collimator 9, heat
Imager 10.The enclosure is containing have powerful connections thermal insulation board, temperature controller, thermometric plate, grey body heater, contact temperature
Probe, collection light illuminator, collimator, the background thermal insulation board are fixed on the inside of outer casing bottom, and the temperature controller is consolidated
Background thermal insulation board middle is scheduled on, the thermometric plate is fixed at temperature controller surface cavities, the grey body heater
It is placed on thermometric plate, the digital thermometer is arranged on outer side surface, and the contact temperature probe placement is in thermometric
