US 12,181,458 B2 · Fiber-optic bundle for in-situ spectral sensor, spectral sensor and method of making and using the same

Abstract

Fiber-optic bundles for infrared spectral analysis of media. The fiber-optic bundles can be used in infrared probes configured to be inserted in media for in-situ characterization of the media. The fiber-optic bundles can include a plurality of optical fibers arranged in a spatial pattern at a sampling end of the bundle to improve a signal of infrared spectral measurements. In-situ probes of the present disclosure can be used for precision farming practices to improve soil health and increase crop yields.

Dependent claims

A fiber-optic bundle, comprising:

a sampling end;
and
a plurality of optical fibers that include:
a first receiver fiber;
a second receiver fiber;
and
a plurality of illumination fibers arranged in an asymmetric pattern at the sampling end, wherein the asymmetric pattern is designed and configured to provide a first illumination intensity incident on the first receiver fiber and a second illumination intensity incident on the second receiver fiber, wherein the first illumination intensity is greater than the second illumination intensity.
