Abstract
The invention discloses a scene-integrating optical system of a dual-lens single CCD (Charge Coupled Device), which is provided with a first imaging system and a second imaging system, wherein the first imaging system is provided with a first lens, a first field diaphragm and a first inversion system; the second imaging system is provided with a second lens, a second field diaphragm, a reflector and a second inversion system; and images of the first imaging system and the second imaging system are synthesized through a scene-integrating lens to be formed on a CCD target surface. Compared with the prior art, the scene-integrating optical system has a reasonable structure design, can be used for synchronously imaging scenes with different distances and different fields on different positions of one CCD through two lenses so as to achieve the purpose of synchronous monitoring, and can be used for effectively applying field information of the CCD to effective monitoring of the scene furthest.
Description
Technical field
The invention belongs to the optical lens technical field, what be specifically related to a kind of twin-lens list CCD closes the scape optical system.
Background technology
Electric locomotive has the advantages such as high speed, heavy duty, high efficiency, high density, low energy consumption, economy, in railway transportation, is widely adopted.Contact line is the non-firm power circuit set up along Along Railway, block of bow collector of electric locomotive obtains electric energy by the contact of sliding friction with it, therefore, the mated condition of block of bow collector of electric locomotive and contact line, and safety problem each other, become the cardinal task of safe operation since electric railway is opened.Because bow net is linear target, if adopt single camera lens to join a CCD, can not bring into play to greatest extent the effect of CCD.For the visual field amount of information CCD is applied to the monitoring of linear target to greatest extent, can pass through two lens imagings to a linear target on the diverse location of a CCD, can be applied to greatest extent effectively monitor scenery to effective CCD visual field amount of information like this.
Summary of the invention
The above-mentioned defect existed for solving prior art, the purpose of this invention is to provide a synchronous imaging of the scenery different distance, different visual fields upper in a CCD, reach the synchronization monitoring purpose twin-lens list CCD close the scape optical system.
For achieving the above object, the technical solution used in the present invention is: this twin-lens list CCD closes the scape optical system, it is characterized in that: have the first imaging system and the second imaging system; Described the first imaging system has the first camera lens, the first field stop and the first relay system; Described the second imaging system has the second camera lens, the second field stop, speculum and the second relay system; The imaging of described the first imaging system and the second imaging system is closed picture by closing the scape prism, is imaged on a CCD target surface.
Described the first field stop and the second field stop are arranged to multi-form, its shape complementarity, and two field stops are by the imaging respectively of first and second relay system.
The camera lens that described the first camera lens and the second camera lens are different focal, different visual fields, it gathers respectively different distance, the scenery of different visual fields.
Adopt the beneficial effect of technique scheme: the scape optical system of closing of this twin-lens list CCD has the first imaging system and the second imaging system, and the camera lens different focal of two imaging systems, different visual field gather different distance, the scenery of different visual fields.The field stop of two camera lenses is arranged to multi-form, its shape complementarity, two field stops, by the imaging respectively of two relay systems, are then closed the scape prism by one and are closed picture, on Cheng Yi CCD target surface.This twin-lens list CCD closes as optical system, reasonable in design, can pass through two camera lens synchronous imagings to the scenery of different distance, different visual fields on the diverse location of a CCD, reach the synchronization monitoring purpose, effective CCD visual field amount of information is applied to monitor on scenery to greatest extent, it is convenient to observe, and contains much information.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail.
Fig. 1 is structural representation of the present invention.
Embodiment
Referring to Fig. 1, twin-lens list CCD shown in the present closes the scape optical system, there is the first imaging system and the second imaging system, described the first imaging system consists of the first camera lens 1, the first field stop 2 and the first relay system 3 that are positioned on same optical axis, the second camera lens 9, the second field stop 8, speculum 7 and the second relay system 6 that the second imaging system is positioned on same optical axis by part form, the imaging of described the first imaging system and the second imaging system is closed scape prism 4 by one and is closed picture, on Cheng Yi CCD target surface 5.
The camera lens that described the first camera lens 1 and the second camera lens 9 are different focal, different visual fields, gather respectively different distance, the scenery of different visual fields.The field stop of the first camera lens 1 and the second camera lens 9 is arranged to multi-form, its shape complementarity, two field stops, by the imaging respectively again of two relay systems 3,6, are closed picture by closing scape prism 4, on Cheng Yi CCD target surface.Can pass through two lens imagings to the scenery different distance, different visual fields on the diverse location of a CCD, can be applied to greatest extent effectively monitor scenery to effective CCD visual field amount of information like this.
Claims (2)
