Description
Technical field
The utility model relates to a kind of luminous energy sniffer, especially a kind of detector of laser energy.
Background technology
Existing detector of laser energy, its photosurface shape nearly all is planar shaped or taper shape, this detector can only carry out energy reception measurement to directional light or the less laser of the angle of divergence, and can't be applied to the measurement of the angle of divergence than the energy of the laser instrument of big or annular, special-shaped light-emitting area.Owing to there not be at present specially at the angle of divergence detector of the laser energy of big or annular, special-shaped light-emitting area, the reception measurement of the energy of the laser instrument of said circumstances has been brought very big inconvenience to the staff of association area.
The utility model content
The purpose of this utility model provides a kind of detector of laser energy, can measure than the energy of the laser instrument of big or annular, special-shaped light-emitting area the angle of divergence.
To achieve these goals, the utility model provides a kind of detector of laser energy, comprise housing, it is characterized in that: be provided with heat sink, cold junction support, thermoelectric pile and special-shaped absorber in the described housing, having the special-shaped absorber that matches with measured light light-emitting area shape is connected with the hot junction of thermoelectric pile, the cold junction of described thermoelectric pile connects the cold junction support, described cold junction support be arranged on described heat sink on.
The hot junction of described thermoelectric pile is uniformly distributed in the outer rim of described special-shaped absorber.
Described cold junction support is provided with equally distributed solder joint, and the cold junction of described thermoelectric pile is connected with described solder joint.
Described thermoelectric pile is composed in series mutually by a plurality of thermopairs.
Described housing is provided with loam cake.
Described special-shaped absorber is dark Heat Conduction Material goods, or the Heat Conduction Material goods of process surface colour processing.
Further, described special-shaped absorber is the Heat Conduction Material goods that scribble black heat conduction, heatproof coating.
The utility model proposes a kind of detector of laser energy, can measure than the energy of the laser instrument of big or annular, special-shaped light-emitting area the angle of divergence, absorber is designed to the polymorphic structure that matches with measured light light-emitting area shape, make the arbitrary luminous point emitted laser of measured light can both vertical irradiation to special-shaped absorber, be convenient to laser is accurately measured.The utility model is simple in structure, is easy to realize, can effectively measure than the energy of the laser instrument of big or annular, special-shaped light-emitting area the angle of divergence, brings great convenience for the work of various equivalent modifications.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model detector of laser energy structural representation.
Embodiment
Fig. 1 is the utility model detector of laser energy structural representation.As shown in Figure 1, the utility model comprises housing 5, be provided with heat sink 4, cold junction support 3, thermoelectric pile 2 and special-shaped absorber 1 in the housing 5, abnormity absorber 1 has the shape that matches with measured light light-emitting area shape, abnormity absorber 1 is connected with the hot junction of thermoelectric pile 2, the cold junction of thermoelectric pile 2 connects cold junction support 3, and cold junction support 3 is arranged on heat sink 4, and the said structure form makes the utility model detector of laser energy that metastable internal environment be arranged.Have the special-shaped absorber that matches with measured light light-emitting area shape 1 and be dark Heat Conduction Material goods, or the Heat Conduction Material goods of handling through surface colour, or scribble the Heat Conduction Material goods of black heat conduction, heatproof coating.Thermoelectric pile 2 is composed in series mutually by a plurality of thermopairs, and the hot junction of thermoelectric pile 2 is uniformly distributed in the outer rim of special-shaped absorber 1; The cold junction 22 of thermoelectric pile 2 is connected on the corresponding solder joint of cold junction support 3, and this solder joint evenly distributes, and making thermoelectric pile 2 is that the center radially distributes with special-shaped absorber 1; The special-shaped absorber 1 of thermoelectric pile 2 and other object are without any physical connection.Cold junction support 3 is arranged on heat sink 4, and with heat sink 4 good thermo-contact is arranged, to guarantee the temperature constant of cold junction 22.The top of housing 5 can also be provided with loam cake 6, is used to block and the irrelevant surround lighting of measurand.
Because the outer shape and the measured light light-emitting area shape of special-shaped absorber 1 match, on measured light 7 light-emitting areas arbitrarily some emitted laser can both vertical irradiation on special-shaped absorber 1, and make special-shaped absorber 1 produce temperature rise with the proportional relation of incident laser energy, thermopair converts the temperature signal on the special-shaped absorber 1 to voltage signal, and the thermoelectric pile 2 that is composed in series mutually by a plurality of thermopairs just can effectively improve signal amplitude.The cold junction of thermoelectric pile 2 since be connected thermal capacitance bigger heat sink 4 on, can keep the relatively stable of temperature, the output signal of thermoelectric pile 2 has just reflected the energy information of measured laser like this, directly measure the amplitude of this signal voltage with secondary instrument, needing just can to obtain the laser energy measured through demarcating.After adopting the special-shaped absorber design of this polymorphic structure, for each luminous point of special-shaped luminophor, special-shaped absorber 1 can both be realized the vertical incidence of loss minimum, has greatly improved the accuracy of measuring.
It should be noted that at last: above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
