Description
Technical field
The utility model relates to the light fixture in a kind of rig camera, especially a kind of laser illuminator.
Background technology
The monitor camera image of when do not have light night, just having no idea to see, the photographic images of also just having no idea.But, a kind of laser illuminator that is used for gamma camera in night illumination is arranged, it can not send the infrared light that wavelength is 810nm when have light night, this infrared light eye response less than but gamma camera can sense, so can take clearly soot-and-whitewash at night.This laser illuminator needs lens to make the Infrared angle that emits change over needed angle, but this angle is fixed.For example, the angle of laser radiation is 30 ° if desired, will the lasing fluorescence pipe is pre-installed, make the angle of laser radiation change into 30 ° by corresponding lens so, the angle of laser radiation is 10 ° if desired, will the lasing fluorescence pipe is pre-installed, make the angle of laser radiation change into 10 degree by corresponding lens so, but it be very inconvenient to change lens.
The someone utilizes and adds that before the lasing fluorescence pipe zoom lens changes the angle of laser radiation and satisfies the shooting demand that the monitor camera zoom is the variation of gamma camera shooting angle at present.But, the distance of laser and the common more little irradiation of the same irradiating angle of light source is just far away more, but the zoom gamma camera that cooperates monitor camera to use needs to take very wide angle sometimes, the light source that if the angle of laser radiation is too little just can not to be made whole image all have can to provide gamma camera to take, if but the irradiating angle of laser accent is big, though very large-scale irradiation light can be provided when gamma camera needs shooting angle big, but need be in the remote object by zoom at gamma camera, because the luminous too big light of angle is concentrated inadequately, causing at a distance, the insufficient strength of irradiate light can't cooperate gamma camera to photograph picture clearly.Especially form by the different lens of the concavo-convex parameter of at least two group polyliths owing to zoom lens, because the logical light rate of every lens all can not be 100%, that have even have only about 90%, so so the decay of light very big just after laser passes the such lens of a lot of pieces is very impracticable.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, for rig camera provides a kind of decay minimum and change irradiating angle laser illuminator easily.
