Hazardous gas detector with 1D array camera

1. A hazardous gas detector comprising:

a housing defining an interior region;

a laser emitting component oriented to emit a laser light away from the housing;

a lens disposed within an aperture defined by the housing, the lens allowing returning infrared light of the laser light to enter the interior region;

a mirror disposed within the interior region and oriented to split the returning laser light into a short wave infrared light and a long wave infrared light; and

a one-dimensional (1D) camera pixel array disposed within the interior region, the 1D camera imaging a planar region that includes an illuminated portion comprising the short wave infrared light.

2. The hazardous gas detector of claim 1 , wherein a plurality of images captured with the 1D camera determines a quantity of a gas present in an environment surrounding the housing based on an amount of absorption of the laser light emitted from the housing.

3. The hazardous gas detector of claim 2 , wherein the gas comprises carbon monoxide or methane.

4. The hazardous gas detector of claim 1 , further comprising at least one optical notch filter disposed within the housing and between the mirror and the 1D camera pixel array.

5. The hazardous gas detector of claim 1 , wherein the 1D camera pixel array is a 1D short wave infrared focal plane array.

6. The hazardous gas detector of claim 1 , wherein the 1D camera pixel array comprises a number of pixels ranging from 128 to 1028.

7. The hazardous gas detector of claim 1 , further comprising a two-dimensional (2D) camera disposed within the housing for imaging of the long wave infrared light.

8. The hazardous gas detector of claim 7 , wherein the 2D camera is a 2D long wave infrared focal plane array.

9. The hazardous gas detector of claim 7 , wherein the 2D camera provides an image for visual inspection by a user.

10. The hazardous gas detector of claim 1 , wherein the mirror is a dichroic mirror.

11. The hazardous gas detector of claim 1 , wherein the housing is operatively coupled to a gimbal mount to allow movement of the housing.

12. A method of detecting hazardous gas comprising:

emitting a laser light from a housing;

receiving an infrared light portion of the laser light through a lens disposed within an aperture defined by the housing;

separating a short wave infrared light from the infrared light portion with a dichroic mirror disposed within the housing; and

analyzing the short wave infrared light with an one-dimensional (1D) camera pixel array disposed within the housing.

13. The method of claim 12 , wherein a plurality of images captured with the 1D camera determines a quantity of a gas present in an environment surrounding the housing based on an amount of absorption of the laser light emitted from the housing.

14. The method of claim 12 , wherein the gas comprises carbon monoxide or methane.

15. A method for determining gas quantification and localization comprising:

emitting and receiving infrared light with a hazardous gas detector;

analyzing a short wave infrared light portion of the received infrared light with a one-dimensional (1D) camera pixel array disposed within a housing of the gas detector;

analyzing a long wave infrared light portion of the received infrared light with a two-dimensional (2D) camera pixel array disposed within the housing; and

evaluating the analyzed information between sensors to determine a presence of a gas.

16. The method of claim 15 , wherein a plurality of images captured with the 1D camera and the 2D camera determines a quantity of a gas present in an environment surrounding the housing based on an amount of absorption of the laser light emitted from the housing.

17. The method of claim 15 , wherein the gas comprises carbon monoxide or methane.

18. The method of claim 15 , wherein the hazardous gas detector is scanned using gimbals to determine the presence of gas in the environment.
