Abstract
The utility model discloses a television borescope photoelectric system which is composed of an optical axis adjusting mechanism and a telescope system. The telescope system is composed of an objective lens group, a reticle and an eyepiece group in turn. The optical axis adjusting mechanism comprises a wedge lens group which is composed of two optical wedge lenses. The frame of each optical wedge lens is provided with a gear, and an adjustable worm gear cooperates with the gears to drive the wedge lenses to rotate. A CCD camera is arranged behind the eyepiece group. The CCD camera is connected with a display through a video optical cable. According to the utility model, the television borescope photoelectric system has the advantages of compact structure and stable and reliable system; the stabilization of an optical system is realized under the condition that a television borescope vibrates; accurate correction is realized; high definition observation is realized; and acquired information are observed by the display, thus the limitations of single observation are solved.
Description
Technical field
The utility model belongs to field of photoelectric technology, is specifically related to a kind of TV borescope electro-optical system.
Background technology
The optical sight that uses optical technology and research and develop, had quite complete theory and the technology of comparative maturity, but only be confined to single observation because its limitation aspect obtaining information reaches, especially the boresight precision on different distance can't satisfy the requirement of actual use.Based on such actual conditions, take improve target observation and identification probability as starting point TV borescope electro-optical system be the important directions of Future Development.The limitation of using in reality based on present domestic visible light observation instrument and loaded down with trivial details and measuring accuracy is low, can't satisfy the requirement of actual use, and the TV screen of high definition and reliable and stable optical system fully combine light, electricity, are important method that solves the problems of the technologies described above.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, and system stability is reliable, realizes the TV borescope electro-optical system of high definition observation.
For achieving the above object, the technical solution adopted in the utility model: this TV borescope electro-optical system, consisted of by optical axis adjusting mechanism and telescopic system, described telescopic system is made of objective lens, graticule, eyepiece group successively, it is characterized in that: described optical axis adjusting mechanism comprises the wedge mirror group that two wedge mirrors form, the housing of wedge mirror is provided with gear, and the adjustment worm screw cooperates the drive wedge-shaped mirrors to rotate with gear; Described eyepiece group rear portion is provided with ccd video camera, and described ccd video camera connects display by vision cable.
Be provided with cover glass before the described wedge mirror group.
Operation wavelength and the ccd video camera operation wavelength of described cover glass, wedge mirror group, objective lens are complementary.
The spectral range of described correct aberrations is 0.48 μ m-0.76 μ m.
Adopt the beneficial effect of technique scheme: the principle of this TV borescope electro-optical system: the objective lens of borescope, graticule, eyepiece group consist of a telescopic system, selected distant place aiming point during boresight, objective lens through borescope is imaged on the dividing plane of borescope, then by eyepiece group and imaging lens the picture of aiming point and the division line of graticule are become simultaneously on the ccd video camera imaging surface, process CCD is converted to electric signal with optical imagery and is sent on the display by system cable, observes when the display television image supplies boresight.Poor pair of wedge mirror of color correction is used for the optical axis adjustment of borescope, when light passes wedge, the light that penetrates always is partial to wedge webbing one side, if during the webbing of two wedges relative with webbing (featheredge is relative with featheredge), the angle of deviation that penetrates is maximum, when the featheredge of the webbing of a wedge and a wedge was relative, the angle of deviation of ejaculation was zero.Just can order about band frame wedge-shaped mirrors when rotating the adjustment worm screw and rotate, thereby cause light shaft offset, utilize this characteristic, carry out the optical axis adjustment, reaching TV borescope stabilized optical system in the situation of vibrations, thus the purpose of realization accurate correction.Information by display observation is obtained has solved the limitation of single observation.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is fundamental diagram of the present utility model.
Embodiment
TV borescope electro-optical system as shown in Figure 1, consisted of by optical axis adjusting mechanism, telescopic system, ccd video camera 6 and display 8, described telescopic system is made of objective lens 3, graticule 4, eyepiece group 5 successively, telescopic system must have enough visual amplifications and relative aperture, to reach the clear cross division line of telling.Described optical axis adjusting mechanism is positioned at the place ahead of telescopic system, and optical axis adjusting mechanism comprises the wedge mirror group 2 that two wedge mirrors form, and the housing of wedge mirror is provided with gear, and the adjustment worm screw cooperates the drive wedge-shaped mirrors to rotate with gear; Described ccd video camera 6 connects display 8 by vision cable 7.Be provided with cover glass 1 before the described wedge mirror group 2.Operation wavelength (spectral range) and the ccd video camera operation wavelength of described cover glass, wedge mirror group, objective lens are complementary, and the visual field of CCD camera lens must be greater than the maximum field of view of telescopic system.The spectral range of described correct aberrations should be chosen in 0.48 μ m-0.76 μ m.Ccd video camera 6 its chips (senser element) must be 1/2 inch CCD video cameras greater than the technical grade of 400,000 pixels, its image definition is the most critical performance index, the standard of weighing image definition is resolution, its pixel count is larger, image is just more clear, ccd video camera and high-resolution telescopic system are closely cooperated, demonstrate fully the high definition image quality advantage of ccd video camera.
