    Abstract: This invention relates to an apparatus for evaluating the quality of rice grains. The apparatus comprises a near infrared spectrometer having a band-pass filter and detectors for detecting the intensity of reflected light from the sample rice; a control device having a memory for storing various values and a calculator for performing various calculations; indicating device for displaying or printing the various calculated values; and a sample case for being filled with the sample rice and being disposed at the measuring portion within the near infrared spectrometer. The apparatus is capable of measuring the content percentages of pre-selected constituent or constituents, such as, of protein, either amylose or amylopectin and moisture of the rice grains, calculating a quality evaluation value of the sample rice based on the measured and calculated values and powers established for the preselected constituents, and displaying the calculated evaluation value of the sample rice.

    Abstract: An accessory is provided to convert a conventional microscope to a microspectrofluorimeter. The accessory includes a filter disc having bandpass filters separated by opaque segments. The filter disc is rapidly and continuously rotated to move the filter sequentially into the optical path between a wideband light source and a microscope sample. Photon counting of radiation from the sample is synchronized to the position of the filters during rotation by means of synchronization marks on the filter disc. The same accessory may be positioned between the sample and a detector to detect emitted light of different frequencies.

    Abstract: In an optical instrument which provides an analog signal representing the intensity of the reflected light from a sample, the sample is irradiated with narrow band wavelength light with the wavelength being repeatedly swept through a range of values to produce a repeating analog signal. Sampling pulses are produced simultaneously with the repeating analog signal to determine a sampling interval. An analog-to-digital converter is connected to receive the analog signal and converts the analog signal to a binary value several times in response to each sampling pulse. The binary values produced in response to each sampling signal are averaged and fed to a digital computer. In the digital computer, the received values are again averaged with other values produced in response to the sampling pulse produced at the same point in the scan of the wavelength irradiating the sample.
