Abstract
The utility model relates to a scanner of a medical used infrared thermal imagery diagnostic system, comprising an object mirror 1, a frame scanning reflecting mirror 2, a frame scanning motor 9, a row scanning motor 10, a detector lens 7 and a detector light sensor 8, which is characterized in that the same axial line which the object mirror 1 of the scanner chamber faces is equipped with the row scanning motor 10, the axial of the row scanning motor 10 is fixed with a round disc and a row scanning rotary reflecting mirror 3 composed of a plurality of concave mirrors which are equally equipped on the round disc, the right facing chamber wall of the concave mirror on the lower portion is equipped with a K type folding reflecting mirror 4, the middle portion of the scanner chamber is equipped with a cone tape reflecting mirror 5, and the lower portion of the cone tape reflecting mirror 5 is equipped with a main reflecting mirror 6.
Description
The utility model relates to a kind of infrared scanner, particularly a kind of scanner of medical infrared thermography diagnostic system.
At present for satisfying the medical and clinical diagnosis, adopted a kind of medical infrared thermography diagnostic equipment, its scanner is made up of the frame scan catoptron of object lens, frame scan driven by motor, row pendulum mirror, catoptron, finder lens, the photosensitive unit of detector that line scan motor drives, the image that is detected enters from object lens, through frame scan catoptron, row pendulum mirror and catoptron imaging is reflexed to finder lens and carry out secondary focusing, become electric signal by the reception of the photosensitive unit of detector and realize.But because row pendulum mirror is to swing to obtain capable signal and carry out line scanning under line scan motor drives, thereby the optical transfer function (OTF) performance is low, pixel is few, and 5 seconds one frames of the frame frequency of acquisition can not satisfy the needs of medical and clinical diagnosis.
It is many that the purpose of this utility model is to design a kind of acquisition pixel, optical transfer function (OTF) performance height, and the frame frequency height can satisfy the scanner that medical and clinical is diagnosed the medical infrared thermography diagnostic system of needs.
The purpose of this utility model is to realize like this, a kind of scanner of medical infrared thermography diagnostic system, include object lens, the frame scan catoptron, the frame scan motor, line scan motor, finder lens, the photosensitive unit of detector, it is characterized in that on the same axis in object lens opposite line scan motor being set in the scanner chamber, be fixed with the line scanning rotating mirror that a plurality of concave mirrors by a disk and the first-class branch setting of disk constitute on the line scan motor axle, the right opposite chamber wall of its underpart concave mirror is provided with K type folding catoptron, the middle part is provided with awl band catoptron in the scanner chamber, and the bottom of awl band catoptron is provided with principal reflection mirror.
The scanner optical transport function performance height of the medical infrared thermography diagnostic system that provides by the utility model, pixel is many, can obtain 654 * 256 pixels, and the frame frequency height can obtain the image light signals of per second imaging 12 frames, can satisfy medical and clinical diagnosis needs.
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a light path principle figure of the present utility model.
Among the figure: 1-object lens 2-frame scan catoptron 3-line scanning rotating mirror 4-folding selects the photosensitive first 9-frame scan motor 10-line scan motor of catoptron 5-awl band catoptron 6-principal reflection mirror 7-finder lens 8-detector
With reference to the accompanying drawings embodiment of the present utility model is described further, a kind of as shown in Figure 1 scanner of medical infrared thermography diagnostic system, include object lens 1, frame scan catoptron 2, frame scan motor 9, line scan motor 10, finder lens 7, the photosensitive unit 8 of detector, be characterized on the same axis in object lens 1 opposite line scan motor 10 being set in the scanner chamber, be fixed with the line scanning rotating mirror 3 that a plurality of concave mirrors by a disk and the first-class branch setting of disk constitute on 10 of the line scan motors, the right opposite chamber wall of its underpart concave mirror is provided with K type folding catoptron 4, the middle part is provided with awl band catoptron 5 in the scanner chamber, and the bottom of awl band catoptron 5 is provided with principal reflection mirror 6.Infrared radiation incides frame scan catoptron 2 through object lens 1, finishes vertical scan direction, from being imaged on awl band catoptron 5 after frame scan catoptron 2 shines principal reflection mirror 6 and projecting on the line scanning rotating mirror 3, finishes horizontal direction scanning; The parallel beam of line scanning rotating mirror 3 outgoing is after K type folding catoptron 4 projects finder lens 7, and secondary imaging converges in the photosensitive unit 8 of detector, gathers the electric signal of imaging from photosensitive unit 8, as shown in Figure 2.Adopt entrance pupil greater than φ 22mm and focal length design parameter greater than 62.55mm, 300 revolutions per seconds than having realized under the slow-speed of revolution to detector 2.09 * 10
6Two-forty scanning as number/second.
