Light measuring probes, light measuring systems, and related methods
A system for measuring light in a tube is provided. The system includes a tube, a light collecting probe configured to absorb light within the tube, a data acquisition system for determining a level of light associated with light absorbed by the light collecting probe, and a motion system for moving the light collecting probe within the tube.
1. A system for measuring light in a tube, the system comprising:
a tube;
a light collecting probe configured to absorb light within the tube, wherein the light collecting probe includes a rod shaped body portion terminating at a light collecting tip portion, the rod shaped body portion being formed of a quartz material, at least a portion of the light collecting tip portion being frosted;
a data acquisition system for determining a level of light associated with light absorbed by the light collecting probe; and
a motion system for moving the light collecting probe within the tube.
2. The system of claim 1 wherein the data acquisition system includes a photodetector configured to (i) receive light from the light collecting probe, and (ii) determine the level of light using the light received from the light collecting probe.
3. The system of claim 1 wherein the data acquisition system includes an optical spectrometer configured to (i) receive light from the light collecting probe, and (ii) determine the light wavelength distribution using the light received from the light collecting probe.
4. The system of claim 1 wherein the motion system is configured to move the light collecting probe along a plurality of motion axes within the tube.
5. The system of claim 4 wherein the plurality of motion axes includes at least one linear motion axis and at least one rotative motion axis.
6. The system of claim 1 wherein the light collecting tip portion has a conical shape.
7. The system of claim 1 wherein the light collecting tip portion has a spherical shape.
8. The system of claim 1 wherein the light collecting tip portion has a partially cylindrical shape.
9. A system for measuring light in a tube, the system comprising:
a tube;
a light collecting probe configured to absorb light within the tube, the light collecting probe including (i) a rod shaped body portion terminating at a light collecting tip portion and (ii) a cap portion for covering the light collecting tip portion to block light from entering the light collecting tip portion, the cap portion defining an aperture configured to allow light to be selectively received by the light collecting tip portion, the aperture being utilized to define an acceptance angle for light received by the light collecting probe;
a data acquisition system for determining a level of light associated with light absorbed by the light collecting probe; and
a motion system for moving the light collecting probe within the tube.
10. The system of claim 9 wherein the data acquisition system includes a photodetector configured to (i) receive light from the light collecting probe, and (ii) determine the level of light using the light received from the light collecting probe.
11. The system of claim 9 wherein the data acquisition system includes an optical spectrometer configured to (i) receive light from the light collecting probe, and (ii) determine the light wavelength distribution using the light received from the light collecting probe.
12. The system of claim 9 wherein the motion system is configured to move the light collecting probe along a plurality of motion axes within the tube.
13. The system of claim 12 wherein the plurality of motion axes includes at least one linear motion axis and at least one rotative motion axis.
