A miniaturized hyperspectral imager is enabled with image sensor integrated with dispersing elements in a very compact
form factor, removing the need for expensive, moving, bulky and complex optics that have been used in conventional
hyperspectral imagers for decades. The result is a handheld spectral imager that can be installed on miniature UAV
drones or conveyor belts in production lines. Eventually, small handhelds can be adapted for use in outpatient medical
clinics for point-of-care diagnostics and other in-field applications.
The invention of optical fiber and semiconductor lasers in the 1960s opened up a cornucopia of applications, notably as a
medium of carrying light signals for communications and sensing applications. Optical fibers provide a fundamental
improvement over traditional methods offering lower loss, higher bandwidth, immunity to electromagnetic interference
(EMI), lighter weight, lower cost, and lower maintenance. By applying a UV laser to "burn" or write a diffraction
grating (A Fiber Bragg Grating-FBG) in the fiber it became possible to reflect certain wavelengths of light, which used
together with an interrogation analyzer (spectral analyzer) precise sensing measurements could be taken. The recent
developments of optoelectronics components in the optical telecommunications field have dramatically enhanced the
capabilities of many components, such as: light sources, fibers, detectors, optical amplifiers, mux/demuxes, switches,
etc. As a result, numerous applications are now available for monitoring strain, stress and pressure in harsh
environments. Examples of current and planned deployments will be presented.
