| Summary: | Spectroscopy is a method that used to identify
chemical structure of substances using its spectral pattern
characteristics. Optical spectroscopy term can be applied to any
kind of optical photon interactions with matter. Raman
spectroscopy essentially shows spectral response like the
wavelength of scattered light is shifted regarding initializing
excitation wavelength. In this paper, we propose a design of low
cost optical-electronic sensor based on Raman spectroscopy.
This low cost optical-electronic sensor employs a violet-blue 405
nm wavelength laser diode, a biconvex lens with 5 cm diameter
and focus point, a test tube, and a Complementary Metal Oxide
Semiconductor (CMOS) sensor. We tested this low cost opticalelectronic sensor based on Raman spectroscopy in dark
condition. Combination of these hardware and components can
provide measurement result to any liquid sample. From this
experiment, even all liquid samples that used to test this
combination of hardware and components are transparent, they
still have different Raman spectra. This combination of
hardware and components can be implemented into some
application for instance body liquid measurement such as blood.
In specific application, we need to employ data analysis and a
bunch of data set which are organized into three different group
such as training data, validation data, and test data group,
combined with this developed instrumentation. |
