Abstract

A device is disclosed. The device contains a first light source configured to excite fluorescence emission of a first contaminant on a surface, and a first optical sensor configured to capture one or more images of the fluorescence emission of the first contaminant.

Claims (30)

1. A device comprising:

a first light source configured to excite fluorescence emission of a first contaminant on a surface;

a first optical sensor configured to capture one or more images of the fluorescence emission of the first contaminant; and

a display configured to depict the surface and a first computer generated image representing the contaminant,

wherein the first computer generated image covers at least a portion of the surface shown on the display,

wherein the first light source comprises illumination of suitable wavelengths and power to kill the first contaminant,

wherein the first computer generated image comprises a first color, wherein the display is configured to depict the first computer generated image comprising a second color, and wherein the first computer generated image comprising the second color covers at least the portion of the surface shown on the display after the first contaminant is killed.

2. The device of claim 1 , wherein the first contaminant comprises at least one pathogen.

3. The device of claim 2 , wherein the first light source comprises illumination of suitable wavelengths and power to deactivate the at least one pathogen.

4. The device of claim 1 , wherein the first light source comprises illumination of suitable wavelengths and power to deactivate the first contaminant.

5. The device of claim 1 , wherein the first light source provides illumination light in an ultraviolet (UV) wavelength range between 260 nm and 290 nm.

6. The device of claim 1 , wherein the first optical sensor is configured to capture at least one image of the fluorescence emission in an ultraviolet (UV) wavelength range between 320 nm and 370 nm.

7. The device of claim 1 , wherein the first optical sensor is configured to capture at least one images of the fluorescence emission in a first wavelength band.

8. The device of claim 7 , wherein the first wavelength band is ultraviolet (UV) band.

9. The device of claim 7 , wherein the first wavelength band is visible band.

10. The device of claim 1 further comprises a second optical sensor configured to capture one or more images of the fluorescence emission of the first contaminant.

11. The device of claim 10 , wherein the second optical sensor is configured to capture one or more images of the fluorescence emission in a second wavelength band.

12. The device of claim 11 , wherein the second wavelength band is ultraviolet (UV) band.

13. The device of claim 11 , wherein the second wavelength band is visible band.

14. The device of claim 1 further comprises a second light source configured to excite fluorescence emission of the first contaminant on the surface.

15. The device of claim 14 , wherein the second light source is a second plurality of light-emitting diodes (LEDs).

16. The device of claim 1 , wherein the first light source is a first plurality of light-emitting diodes (LEDs).

17. The device of claim 1 further comprises:

a second light source configured to excite fluorescence emission of the first contaminant on the surface; and

a second optical sensor configured to capture one or more images of the fluorescence emission of the first contaminant;

wherein the first light source provides illumination light in a first wavelength range;

wherein the second light source provides illumination light in a second wavelength range;

wherein the first optical sensor is configured to capture at least one images of the fluorescence emission in a first wavelength band; and

wherein the second optical sensor is configured to capture at least one images of the fluorescence emission in a second wavelength band.

18. The device of claim 17 , wherein the first light source comprises illumination of suitable wavelengths and power to deactivate the first contaminant.
