Paper Abstract
For simultaneous measurement of multi-components on-site like factories, the ultra-compact (diameter: 9[mm], length:
45[mm], weight: 200[g]) one-shot ATR (Attenuated Total Reflection) Fourier spectroscopic imager was proposed.
Because the proposed one-shot Fourier spectroscopic imaging is based on spatial-phase-shift interferometer,
interferograms could be obtained with simple optical configurations. We introduced the transmission-type relativeinclined
phase-shifter, that was constructed with a cuboid prism and a wedge prism, onto the optical Fourier transform
plane of infinity corrected optical systems. And also, small light-sources and cameras in the mid-infrared light region,
whose size are several millimeter on a side, are essential components for the ultra-compact spectroscopic configuration.
We selected the Graphite light source (light source area: 1.7×1.7[mm], maker: Hawkeye technologies) whose radiation
factor was high. Fortunately, in these days we could apply the cost-effective 2-dimensional light receiving device for
smartphone (e.g. product name: LEPTON, maker: FLIR, price: around 400USD). In the case of alcoholic drinks factory,
conventionally workers measure glucose and ethanol concentrations by bringing liquid solution back to laboratories
every day. The high portable spectroscopy will make it possible to measure multi-components simultaneously on
manufacturing scene. But we found experimentally that absorption spectrum of glucose and water and ethanol were
overlapped each other in near infrared light region. But for mid-infrared light region, we could distinguish specific
absorption peaks of glucose (@10.5[μm]) and ethanol (@11.5[μm]) independently from water absorption. We obtained
standard curve between absorption (@9.6[μm]) and ethanol concentration with high correlation coefficient 0.98
successfully by ATR imaging-type 2-dimensional Fourier spectroscopy (wavelength resolution: 0.057[μm]) with the
graphite light source (maker: Hawkeye technologies, type: IR-75).
