Abstract
The utility model relates to a reflection type irradiation resisting camera suitable for 1000 Gy/h and lower radiation environments. The camera comprises a CCD (charge coupled device) camera body (1) which is installed in a shielding material (2), and the outer side of the shielding material (2) is coated by a shell (3). A forward reflecting mirror (4) is installed in front of the lens of the CCD camera body (1), an included angle between the forward reflecting mirror (4) and the lens of the CCD camera body (1) is 45 degrees, and an included angle between the center of a target (5) to be observed in front of the forward reflecting mirror (4) and the forward reflecting mirror (4) is 45 degrees. According to the reflection type irradiation resisting camera, the irradiation defending capability of the CCD camera is improved, and therefore, the CCD irradiation resisting camera can be applied in environments with high ray dose.
Description
Technical field
The utility model relates to a kind of video camera of anti-irradiation; Particularly relate to a kind of ccd video camera protection radianting capacity that can make and improve, thereby make the CCD video camera of anti-irradiation can be applicable to the reflective video camera of anti-irradiation that is applicable to 1000Gy/h and following radiation environment in the high roentgen dose X environment.
Background technology
Have the video camera of anti-irradiation that in nuclear environment, uses now, pick-up lens is directly facing to target, because the restriction of ccd video camera protection radianting capacity is difficult in the high roentgen dose X environment and uses.
CCD is the abbreviation of Charge Coupled Device (charge coupled device), and it is a kind of semiconductor imaging device, thereby has highly sensitive, anti-high light, advantages such as distortion is little, volume is little, the life-span is long, anti-vibration.
The working method of ccd video camera: the image process lens focus of subject is to the CCD chip; CCD is according to the electric charge of the power accumulation corresponding proportion of light, and the electric charge of each pixel accumulation is under the control of system sequence, and pointwise moves outward; After filtering, processing and amplifying, form vision signal output.Vision signal is connected to the video inputs of monitor or television machine, just can see the video image identical with original image.
The utility model content
To the problems referred to above; The main purpose of the utility model is to provide a kind of ccd video camera protection radianting capacity that can make to improve, thereby makes the CCD video camera of anti-irradiation can be applicable to the reflective video camera of anti-irradiation that is applicable to 1000Gy/h and following radiation environment in the high roentgen dose X environment.
The utility model solves above-mentioned technical problem through following technical proposals: the reflective video camera of anti-irradiation of a kind of 1000Gy/h of being applicable to and following radiation environment; Said video camera comprises the ccd video camera body; Said ccd video camera body is installed in the protective materials; The outside of said protective materials is that shell coats; Camera lens the place ahead of said ccd video camera body is equipped with a normal reflection mirror, and the angle of the camera lens of said normal reflection mirror and ccd video camera body is 45 °, and the center of the target that the needs in the place ahead of said normal reflection mirror are observed and the angle of normal reflection mirror are 45 °.
In the practical implementation example of the utility model, said normal reflection mirror is an optical coating normal reflection mirror.
In the practical implementation example of the utility model, said ccd video camera body is to focus or the video camera of zoom lens.
The positive progressive effect of the utility model is: the reflective video camera of anti-irradiation that is applicable to 1000Gy/h and following radiation environment that the utility model provides has the following advantages: the utility model can make ccd video camera protection radianting capacity improve, thereby the CCD video camera of anti-irradiation can be applicable in the high roentgen dose X environment.
