    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for measuring the concentration of a component in an object. SOLUTION: The apparatus for measuring the concentration of a component comprises: a light source that generates light having a first wavelength band for the component; an RF (radio frequency) signal generator that generates a signal having a predetermined frequency band so that light having a second wavelength band can be generated from the light having the first wavelength band; a tunable filter that generates a positive-order beam and a negative-order beam, which have the second wavelength band, by an RF signal; a first detector that detects a first output beam reflected from or transmitted through the object onto which the positive-order beam generated by the filter has been radiated; and a second detector that detects a second output beam reflected from or transmitted through a reference matter onto which the negative-order beam generated by the filter has been radiated. An intensity relationship equation between the positive-order beam and the negative-order beam is previously stored. An input beam to the object is calculated from the second output beam from the reference matter using the intensity relationship equation, and then the concentration of the component in the object is measured from an absorbance calculated using the first output beam and the calculated input beam.

    Abstract: PURPOSE:To obtain an image of a desired wavelength without using a mechanical mobile part, by providing a pinhole, a collimator, an acoustooptic filter, a focusing lens, a pinhole and an image intensifier, respectively. CONSTITUTION:Light is received from an object 14 via a pinhole 2 provided at a part of the outer wall of a camera 1 and then made incident to an acoustooptic filter 6 through a collimator lens 5 provided in the camera 1 and in the form of parallel beams. The filter 6 delivers only a specific wavelength of said parallel beams with a polarized angle. The wavelength is selected by a focusing lens 7 and a pinhole 3 and then amplified by an image intensifier 8 to display an image of a specific wavelength component on a screen 10. A desired wavelength is manually supplied to a wavelength controller 11, and then the voltage of a frequency corresponding to the selected wavelength is applied to a transducer 61 of the filter 6 via a voltage controlling variable frequency oscillator 12.
