Imaging device with focused illumination
An imaging system comprising a parabolic reflector having a base and defining a first axis, a light source disposed proximate the base essentially along the first axis, an imaging device comprising a zooming lens having a second axis, the imaging device being disposed in front of the light source along the first axis such that the second axis and the first axis are essentially coincident.
1. An imaging system having a forward and rearward orientation, said system comprising:
at least one parabolic reflector having a base and a focus, and being configured to substantially collimate light;
at least one a light source disposed near or essentially at said focus of said parabolic reflector forward of said base and being configured to emit light toward said at least one parabolic reflector such that said at least one parabolic reflector collimates said light to emit substantially collimated light; and
an imaging device disposed forward of said at least one light source and comprising a zooming lens having an optical axis essentially parallel with said substantially collimated light, said imaging device configured to image a field of view along said optical axis forward of said imaging device and away from said at least one light source.
2. The imaging system of claim 1 , wherein said at least one parabolic reflector comprises machined and polished aluminum.
3. The imaging system of claim 1 , further comprising a second imaging device configured with a short field of view compared to said field of view of said imaging device.
4. The imaging system of claim 3 , wherein said second imaging device has a field of view opposite of said field of view of said imaging device.
5. The imaging system of claim 3 , further comprising one or more LED lights for illuminating said field of view of said second imaging device.
6. The imaging system of claim 1 , further comprising one or more batteries within said housing.
7. The imaging system of claim 1 , wherein said at least one parabolic reflector has a reflector axis.
8. The imaging system of claim 7 , wherein said at least one light source is disposed along said reflector axis.
9. The imaging system of claim 8 , wherein said reflector axis is coincident with said optical axis.
10. The imaging system of claim 9 , wherein said at least one parabolic reflector is a single parabolic reflector.
11. The imaging system of claim 1 , wherein said at least one light source is configured to emit light normal to said optical axis.
12. The imaging system of claim 1 , wherein said at least one light source is an LED.
13. The imaging system of claim 7 , wherein further comprising:
at least one adjustment mechanism operatively connected between said imaging device and said parabolic reflector such that movement of said adjustment mechanism moves the optical axis relative to the reflector axis.
14. The imaging system of claim 13 , further comprising a housing containing said imaging device.
15. The imaging system of claim 14 , wherein said adjustment mechanism comprises an adjustment member, a portion of which is accessible from outside said housing.
16. The imaging system of claim 15 , wherein said housing comprises a front face, at least a portion of which is transparent, and wherein said imaging device is at least partially mounted to said front face, and further comprising a complaint gasket between said imaging device and said front face, and wherein said cooperating member is a bracket disposed proximate said front face, and wherein said adjustment member comprises a plurality of adjustment screws passing through said bracket, such that rotating said adjustment screws causes said imaging device to move relative to said front face.
17. The imaging system of claim 10 , wherein said at least one parabolic reflector has diameter of about 6 inches.
18. The imaging system of claim 7 , wherein said light source radiates light essentially perpendicular to said reflector axis.
19. The imaging system of claim 14 , further comprising an elongated member operatively connected to said housing for positioning said imaging device.
20. The imaging system of claim 14 , wherein a portion of said housing comprises at least a portion of said reflector.
21. The imaging system of claim 14 , wherein said housing comprises a front face, at least a portion of which is transparent.
22. The imaging system of claim 14 , wherein said housing comprises a seat defined around its forward perimeter allowing said housing to seat in pipes having about the same diameter as said housing.
