Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The present embodiment provides a kind of Ia supernova telemetry apparatus for demonstrating, as shown in Figure 1, comprise the casing 10 be made up of nontransparent sheet material, isolated extraneous light interference, the side of described casing 10 is provided with one and punches, the described place of punching is mounted with a ray-collecting cylinder 20, except the part that punches inside described casing 10, all be lined with black light-absorbing material, reduce box house reflective, there is the LED point light source that two luminosity are identical described casing 10 inside, described two LED point light source are all placed in the plane of described ray-collecting cylinder 20 primary optical axis, a LED point light source 31 near described ray-collecting cylinder is as the nearly star model of Ia supernova, another LED point light source 32 away from described ray-collecting cylinder is as Ia supernova star model far away.Can be, but not limited to, two described LED point light source are circumscribed with high-precision regulated power supply, identical to guarantee two LED point light source luminosity.
As shown in Figure 2, the one end being positioned at the described ray-collecting cylinder 20 of described casing 10 outside is provided with a photodiode 40, and described photodiode is connection signal amplifier 50, AD analog to digital converter 60, data acquisition computer 70 successively.
During use, the brightness of two LED point light source luminescences is identical, when one of them is luminous, another must extinguish, interfere with each other to avoid light, the light of described LED point light source is collected in one end that described ray-collecting cylinder 20 is positioned at cabinet interior, and by described photodiode 40, light signal is converted into electric signal, through signal amplifier 50, AD analog to digital converter 60 transfers data to described data acquisition computer 70 after processing, according to ray-collecting cylinder 20 from Ia supernova model more away from, the light intensity observed is also lower, apparent brightness according to the Ia supernova model observed just can calculate the distance of Ia supernova model from ray-collecting cylinder 20.
Can be, but not limited to, described two LED point light source are placed on height adjustable optical bench, and optical bench can move in casing, for regulating the distance between described LED point light source and ray-collecting cylinder 20.
As shown in Figure 3, described ray-collecting cylinder 20 is connected with described casing 10 place of punching by a rotation axis 80, and described rotation axis 80 can do and low-anglely to horizontally rotate, can aim at one of them LED point light source collecting light.
Therefore, due to owing to adopting the principle that the model of each celestial body is directly perceived, clear, show the range finding of Ia supernova accurately, be convenient to the understanding of teaching and student, excite the interest of student.
