Optimizing Speed and Sensitivity of
Hyperspectral Imaging System
(OSSHIS)
Phiwat Klomkaew
Hyperspectral imaging (HSI) is a powerful
tool that uses images at multiple wavelengths
to provide spectral information that
allows one to uniquely characterize any two
unique materials or substances. The applications
of HSI are numerous, from medicine
to remote sensing. For microscopy and cancer
detection applications, our team has previously
designed an HSI system coupled
with an inverted fluorescence microscope
using an LED-based light source. This current
research sought to optimize the previous
HSI system, particularly focusing on
replacing 16 regular LEDs with higherpower
LED chips and adjusting the setup of
the light source to minimize light losses.
From the spectraradiometric output measurements,
we found that the new HSI system
showed the increased power output of
the new LED chips and the optimized optical
geometry due to 100 times more power
than the previous design.
