Abstract

A method for quantifying an exposure dose for a surface is disclosed. The method may include emitting one or more beams of 222 nm light onto a portion of the surface using one or more far ultraviolet (UV) light sources capable of emitting 222 nm light, the portion of the surface being coated with one or more fluorescent coatings. The method may include capturing images of the portion of the surface. The method may include adjusting one or more image characteristics for the captured images using one or more filtering methods. The method may include generating a histogram of the adjusted images based on the one or more filtering methods. The method may include determining a pixel surface area for the generated histogram. The method may include calculating the exposure dose for the surface based on the generated pixel surface area and a predetermined calibration curve.

First claim

What is claimed:

1. A system for quantifying an exposure dose on a surface, the system comprising:
one or more far ultraviolet (UV) light sources configured to emit one or more beams of 222 nm light onto the surface, the surface being coated with one or more fluorescent coatings;
one or more image detection devices configured to capture one or more images of the surface when the one or more beams of 222 nm light from the one or more far UV light sources hit the surface; and
one or more controllers communicatively coupled to the one or more image detection devices, the one or more controllers including one or more processors and memory, the one or more processors including a set of program instructions stored in memory, the set of program instructions configured to cause the one or more processors to:
adjust one or more image characteristics for the one or more captured images using one or more filtering methods;
generate a histogram of the one or more adjusted images based on the one or more filtering methods;
determine a pixel surface area for the generated histogram; and
calculate the exposure dose for the surface based on the generated pixel surface area and a predetermined calibration curve, wherein the predetermined calibration curve is generated using a meter device.

2. The system of claim 1 , wherein the one or more filtering methods include adjusting at least one of:
brightness, saturation, or hue.

3. The system of claim 1 , wherein the one or more light sources are integrated with a portion of an aircraft cabin.

4. The system of claim 3 , wherein the one or more light sources are integrated with a portion of a lavatory of the aircraft cabin.

5. The system of claim 3 , wherein the one or more light sources are integrated with an overhead portion above an aircraft seat of the aircraft cabin.

6. The system of claim 1 , wherein the one or more image detection devices include one or more cameras.

7. The system of claim 6 , wherein the one or more cameras include one or more mobile device cameras.

8. A method for quantifying an exposure dose for a surface, the method comprising:
emitting one or more beams of 222 nm light onto a portion of the surface using one or more far ultraviolet (UV) light sources capable of emitting 222 nm light, the portion of the surface being coated with one or more fluorescent coatings;
capturing one or more images of the portion of the surface;
adjusting one or more image characteristics for the one or more captured images using one or more filtering methods;
generating a histogram of the one or more adjusted images based on the one or more filtering methods;
determining a pixel surface area for the generated histogram; and
calculating the exposure dose for the surface based on the generated pixel surface area and a predetermined calibration curve, wherein the predetermined calibration curve is generated using a meter device.

9. The method of claim 8 , wherein the one or more filtering methods include adjusting at least one of:
brightness, saturation, or hue.

10. The method of claim 8 , further comprising:
adjusting a position of at least one of the one or more light sources based on the calculated exposure dose.

11. The method of claim 8 , wherein the one or more light sources are integrated with a portion of an aircraft cabin.

12. The method of claim 11 , wherein the one or more light sources are integrated with a portion of a lavatory of the aircraft cabin.

13. The method of claim 11 , wherein the one or more light sources are integrated with an overhead portion above an aircraft seat of the aircraft cabin.
