Specific embodiment
The utility model is described in detail with reference to specific embodiments and the drawings explanation.
As shown in Figure 1, 2, 3, a kind of utilization temperature control system realizes the inteference imaging spectrometer of actively focusing, including along light path
Preposition component 8 of looking in the distance, collimation mirror assembly 9, interferometer component 10, fourier mirror assembly 11 and the focal plane group for setting gradually are put down in transmission
Part 12.By Optical system, fourier mirror assembly is using the thermalization optical design scheme that disappears, it is ensured that interference surface is in complicated work
Stabilization under environment；Preposition component of looking in the distance is using long-focus, large relative aperture Cassegrain system；Increase by preposition component of looking in the distance
Plus temperature control system, temperature control is carried out using temperature control system, fine setting interference imaging is realized by expanding with heat and contract with cold for structural material
Purpose for image planes 13 of spectrometer, so as to ensure that the imaging surface and interference surface of imaging spectrometer overlap.
Preposition component of looking in the distance includes long-focus, large relative aperture Cassegrain imaging system and temperature control focusing component, jam
Green's imaging system includes primary mirror, secondary mirror, correction mirror and associated structural component.
Temperature control focusing component includes heat insulating mattress, temperature control fine setting titanium alloy lens barrel, heating plate and thermistor.Heating plate silicon
Rubber is bonded at temperature control fine setting titanium alloy lens barrel outer surface, and heating plate is evenly arranged the thermal expansion of guarantee temperature control fine setting titanium alloy lens barrel more
Uniformly.Meanwhile, 4 thermistors, Real-time Feedback measurement temperature control fine setting titanium alloy mirror are bonded on temperature control fine setting titanium alloy lens barrel
The temperature of cylinder.Heat insulating mattress is installed on temperature control fine setting titanium alloy lens barrel and the junction of other components, using heat-insulated installation, it is to avoid heat
Amount is conducted to secondary mirror assembly and primary mirror component.
This example is with heat insulating mattress as glass steel material, thermistor as RTD, heating plate be copper heating plate and titanium alloy
As a example by lens barrel, operation principle is as follows：
Copper power-up backing temperature change is made by power supply, is conducted and is finely tuned titanium alloy lens barrel in temperature control, finely tuned using temperature control
The hot expansion property regulation primary mirror of titanium alloy lens barrel and the interval of secondary mirror, realize change system fine setting inteference imaging spectrometer once
The purpose of image planes 13.
According to Δ L=L* α * (T1-T0),
Wherein Δ L is the interval of primary mirror and secondary mirror, and L is the length that titanium alloy lens barrel is finely tuned in temperature control, and α is hot swollen for titanium alloy
Swollen coefficient, T1 is temperature control is finely tuned the temperature value of titanium alloy lens barrel by heating plate, and the initial of titanium alloy lens barrel is finely tuned in T0 temperature controls
Temperature value.It can be seen that when heating plate makes temperature control fine setting titanium alloy lens barrel temperature higher, the interval delta L of primary mirror and secondary mirror increases
Greatly, image planes of system are toward positive direction micro-shifting；When heating plate make temperature control finely tune titanium alloy lens barrel temperature it is relatively low when, primary mirror and secondary mirror
Interval delta L reduce, image planes of system are final to realize once by a positive negative sense micro-shifting for image planes toward negative direction micro-shifting
The fine setting of image planes.
It is that the temperature control with good heat and power performance is finely tuned that the regulation designed using the hot expansion property of material drives original paper
Titanium alloy lens barrel.
