Description

The dual-magnification technique photoelectric image conversion equipment that is used for the visual optical mirror
The utility model relates to the photoelectric image conversion equipment of visual optical mirror.
People can convert the optical imagery that visual optical mirror (telescope, microscope) is observed to be monitored device or computer Recognition electricity picture signal by the photoelectric image conversion, can carry out real time record to image.But for a long time, owing to be used for the image sensor chip cost height of photoelectric image conversion equipment, driving circuit complexity, volume is big, therefore, has limited the generally use of photoelectric image conversion equipment, for example, be not preferably the photoelectric image conversion equipment that telescope at a low price is equipped with high price.Along with the development of image sensor chip technology, had especially in recent years a kind of on chip piece the low price of integrated light-sensitive array device and treatment circuit, the imaging sensing chip that volume is little provides possibility for preparation photoelectric image conversion equipment at a low price.
The purpose of this utility model provide a kind of simple in structure, cost is low, have two enlargement ratios, the dual-magnification technique photoelectric image conversion equipment that is used for the visual optical mirror easy to use.
The dual-magnification technique photoelectric image conversion equipment that is used for the visual optical mirror of the present utility model comprises camera and connects two assemblies of lens barrel, said camera comprises the housing with positioning boss, cutoff filter, image sensor chip and driving circuit thereof are installed in the housing from bottom to top successively, wherein the photosurface of image sensor chip is positioned on the imaging surface of visual optical endoscope objective lens, the feed line of driving circuit and picture signal output line stretch out housing, are useful on housing and connect the external thread that lens barrel links to each other; The said lens barrel that connects comprises by the tubular shell of positioning boss boundary for last lens barrel and following lens barrel, in last lens barrel and following lens barrel, be fixed with image transferring lens and field lens respectively and form the relaying camera lens, have and the stubborn internal thread that connects of external thread of camera housing and the locating surface that cooperates with the camera positioning boss at the inwall of last lens barrel.
Usually, image sensor chip adopts the quick array device of light harvesting and treatment circuit in the cmos imaging sensing chip on the chip piece.
During use, camera is inserted separately in the eyepiece stalk of visual optical mirror (as telescope), utilize the positioning boss location, the photosurface of image sensor chip is overlapped with the imaging surface of telescope objective, at this moment, image sensor chip can directly convert optical imagery to the electricity image, its imaging multiplying power is 1, the imaging definition height, because it is much smaller that image sensor chip photosurface size is compared the linear field size of telescope objective, therefore only can only cut middle body and carry out photoelectric image conversion in the visual field of object lens with camera, its visual field is little, but the resolution height.When need be when the whole-view field imaging of telescope objective be to the photosurface of image sensor chip, camera can be screwed in and connect on the lens barrel, to connect lens barrel again inserts in the telescopical eyepiece stalk, utilization connects the positioning boss location on the lens barrel, the imaging surface that guarantees telescope objective translates on the photosurface that looks like image sensor chip by the relaying camera lens, convert optical imagery to the electricity image, its imaging multiplying power is reduced into Γ ≈ d/D, and (d is an image sensor chip photosurface size, D is the linear field size of telescope objective), at this moment, the visual field enlarges, and brightness strengthens.
The utility model is simple in structure, cost is low, because it has camera and connects two subassemblies of lens barrel, can use camera separately, also can make camera and connect lens barrel and unite use, and have 1 with the function of the two enlargement ratios of Γ, select the application of small field of view, high-resolution application or big visual field, high brightness easily for the user.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the camera synoptic diagram in the utility model;
Fig. 2 connects the lens barrel synoptic diagram in the utility model;
Fig. 3 is a camera and connect lens barrel and connect synoptic diagram.
With reference to Fig. 1, camera in the utility model comprises the housing 1 with positioning boss 3, cutoff filter 4 is installed in the housing from bottom to top successively, image sensor chip 7 and driving circuit 10 thereof, the feed line 8 and the picture signal output line 9 of driving circuit stretch out housing, lens barrel 5 on the housing closely cooperates with the telescope ocular lens barrel, and the photosurface 6 of image sensor chip is overlapped just with the telescope objective imaging surface by boss 3 location, on housing, be useful on and connect the external thread 11 that lens barrel links to each other.
With reference to Fig. 2, the lens barrel that connects in the utility model comprises by the tubular shell of positioning boss 12 boundary for last lens barrel 16 and following lens barrel 13, in last lens barrel 16 and following lens barrel 13, be fixed with image transferring lens 15 respectively and field lens 14 is formed the relaying camera lenses, have and stubborn internal thread 17 that connects of casing of pick-up head extracorporeal thread and the locating surface 2 that cooperates with camera positioning boss 3 at the inwall of last lens barrel 16.
Shown in Figure 3, be that camera is screwed in by screw thread and connects on the lens barrel, when descending lens barrel 13 to insert in the telescope ocular tube, utilize positioning boss 12 location, be imaged on the entrance pupil of image transferring lens 15 by the emergent pupil of field lens 14 object lens, be imaged onto once more on the photosurface 6 of image sensor chip through cutoff filter 4 again, and the field image that telescope objective is become all converts the electricity image to by image sensor chip.Generally, field lens is made of single element lens, and image transferring lens can repeatedly be put by a slice eyeglass (shown in Figure 2) or three eyeglasses and form (as shown in Figure 3).The object space relative opening of image transferring lens is complementary, to satisfy the Γ x magnification through the picture side's relative aperture with telescope objective.
The utility model can be used for telescope, also can be used for microscope.
