    Abstract: A liquid fuel property detection apparatus includes a fuel passage, a light emitting device for emitting a light including a plurality of predetermined wavelengths toward the fuel in the passage, a light receiving device for receiving the light passing through the fuel, and a calculation unit for calculating the concentration of at least one of aroma, paraffin and olefin, which are hydrocarbon component components contained in the fuel. The calculation unit calculates the concentration of a specific component, which is one of aroma, paraffin and olefin, based on the reference transmittance of light in the specific component and the actual transmittance calculated from the amount of light emitted by the light emitting device and the amount of light received by the light receiving device with respect to each wavelength of the light.

    Abstract: A linear axis spectral analysis system is enclosed. The spectral analysis system utilizes a prism-volume holographic transmission grating-prism combination to achieve a linear axis between input and detector. This design, when held with low thermal expansion materials, is extremely insensitive to temperature and vibration, allowing for enhanced accuracy without the need of temperature control. Further, the spectral analysis system provides the ability for extreme compactness.

    Abstract: Detector apparatus includes a dispersive prism (10) and a diffraction grating (11) of the type which produces only zero and first order diffraction patterns. Located behind the diffraction grating (11) so as to interact with the first harmonic content of the diffraction patterns is a Moire grating (12) having half the pitch of the diffraction grating (11). Detector means including at least two pairs of detectors (13-16) is located behind the Moire grating (12) to detect the presence of Moire fringes.
