Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
The interference optical detection system that the utility model provides, mainly comprise light source 1, first diaphragm 2, first lens 3, spectroscope 4, second lens 5, second diaphragm 6, charge-coupled image sensor 7 and catoptron 8, described first lens 3 are arranged on the beam projecting direction of light source 1, spectroscope 4 is arranged on the first lens 3 rear, the normal direction of the second lens 5 is mutually vertical with the normal direction of the first lens 3, described charge-coupled image sensor 7 is arranged on the rear side of the second lens 5, and described catoptron 8 is arranged on the rear side of spectroscope 4.
First diaphragm 2 is arranged between light source 1 and the first lens 3.Second diaphragm 6 is arranged between the second lens 5 and charge-coupled image sensor 7.System also comprises detecting device 9, is arranged on the opposite side that spectroscope 4 is relative with the second lens 5.The light that light source 1 sends is divided into two parts by spectroscope 4 after the first lens 3, and a part arrives catoptron 8, and another part arrives detecting device 9.After the interference of light that catoptron 8 and detecting device 9 reflect by the second lens 5 after arrive charge-coupled image sensor 7.
Its principle of work is: micro-cantilever, when absorption surface absorbs infrared radiation, can produce deformation.The light that light source 1 sends becomes directional light injection through the effect of the first diaphragm 2 and the first lens 3, and be radiated on spectroscope 4, this Shu Guang is divided into two parts by spectroscope 4, a part of directive catoptron 8, and another part vertically downward directive is detected the detecting device 9 in face.The light that catoptron 8 and detecting device 9 reflect interferes when again meeting, and is imaged on charge-coupled image sensor 7 by the second lens 5.In this system, focal plane arrays (FPA) can also be placed by by detecting device 9 place, realize the detection of infrared image.The rotation size of its micro-cantilever is relevant with the distribution of interference fringe.
The interference optical detection system that the utility model provides is interfered light by arranging structure, face place will be detected and place focal plane arrays (FPA), realize the detection of infrared image, the rotation size achieving micro-cantilever is relevant with the distribution of interference fringe, thus improves precision.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done is all in protection domain of the present utility model.
