Abstract: In accordance with embodiments of the present invention, a goniospectrophotometer is provided for quickly obtaining a goniospectrum using a goniospectrophotometer. In some embodiments, a parabolic reflector is used to optically transform the angular space of a source at the parabola focus into a linear space and facilitate the use of a single diffracting element and area camera to simultaneously measure the angular spectrum of the source. Spectra corresponding to zenith angles of light reflection by the parabolic reflector can be acquired by a detector and analyzed in a computer.

Abstract: Color measurement using compact devices is described herein. A color measurement device can include a diffraction grating that receives light reflected from a surface whose color is being measured. The diffraction grating is responsive to a control signal to split selected components from the reflected light and to admit the components in sequence to a sensor. The components can correspond to a selected wavelength or frequency of the reflected light. The sensor measures the energy or power level of each of the admitted components. The device can support determining a spectral representation of the color of the surface by generating output signals representing the various energy or power levels of each component of the light reflected from the surface.

Abstract: Optical color sensor using diffractive elements. Semiconductor fabrication processes are used to form diffraction gratings as part of a photosensor. In a first embodiment, photosensors such as photodiodes are formed on a substrate, and diffraction gratings of fixed spacing are formed using the metallization layers common to semiconductor fabrication techniques. In a second embodiment, a linear photodiode array is formed on a substrate, and a diffraction grating with changing spacing is formed in the metal layers, providing a continuous color sensor. Other metal layers commonly used in semiconductor processing techniques may be used to provide apertures as needed.

Abstract: A produce recognition system and method which use an internal reference to calibrate a produce data collector. The produce data collector collects first data from an external reference, collects second and third data from an internal reference, and collects fourth data from a produce item. A computer determines a first calibration value from the first and second data and a second calibration value from the third data and applies the first and second calibration values to the fourth data to produce fifth data. The computer further obtains sixth data from reference produce data and compares the fifth and sixth data to identify the produce item.

Abstract: An apparatus and method for utilizing NIR spectrography for measuring major constituents of substances in real time includes a monochromator or other sensor having no moving optical parts. At least one of the monochromator and the substance are moving relative to one another. An NIR radiation source irradiates a substance and the reflected or passed-through radiation is transmitted to the monochromator, which isolates and detects narrow portions of the received spectrum. By analyzing the intensities and wavelengths of the received radiation, the presence and amount of major constituents of the substance can be determined.

The spectrally stable light is directed at a reflective target. A light sensor receives reflected light from the surface of the target through the fiber optic cable and generates reflected spectral data. A computer receives the reflected spectral data and calculates a signal based on the reflected spectral data.

Abstract: An integrated-optic spectrometer is disclosed for analyzing the composition of light reflected off a sample under analysis. In a simplified embodiment, the spectrometer includes a buffer, located on the top of a substrate, which is etched to create a diffraction grating having grating lines. The diffraction grating and grating lines are formed to provide diffraction of discrete wavelengths of light, while providing for maximum transmission of non-diffracted wavelengths. A waveguide is fabricated on top of the etched buffer through which the reflected light is directed. A photodiode detector array is located above the waveguide into which the diffracted wavelengths are diffracted, providing an analysis of the composition of the reflected light. A clad encompasses the integrated-optic spectrometer, thereby providing protection from outside interference.
