The present invention relates to an internal quality measuring apparatus for measuring an internal quality of an object, and the apparatus has a conveying device, a detecting device, a light projecting device, a light receiving device, an analyzing device and a pseudo-object member interposing device, and the analyzing device compares light received with a pseudo-object member, with reference data preliminarily stored, and correct a result of the analysis, based thereon.

Measurement apparatus for measuring internal quality of object

The refraction type non-destruction measuring apparatus of the present invention has a prism having a predetermined refractive index, projecting means for projecting near infrared light onto an object to be examined through the prism, a contact material filling the space between the object to be examined and the prism and having a refractive index set in conformity with the characteristic of the object to be examined, and light receiving means for receiving the internal reflected light of the light having entered the interior of the object to be examined through the contact material and the prism.

Refraction type non-destruction measuring apparatus

Near infrared rays of .lambda.1, .lambda.2, .lambda.3 in wavelength which are different from and near to one another are irradiated from a light source (2) to a part being measured (F) of a living body in such a state that vein bloodstream at the part being measured is stopped by applying a press force of a cuff (8), and the intensities of the transmitted near infrared rays of .lambda., .lambda.2, .lambda.3 in wavelength are detected by a photodetector (4) at the same time. In a processing circuit (14), the absorbance secondary differential value of the near infrared rays by the part being measured (F) is calculated on the basis of the transmitted light intensity detection values thus detected at the same time with respect to the three wavelengths, the variation width thereof within a predetermined time is calculated and then the blood sugar value in the living body is determined from the absorbance secondary differential value variation width on the basis of a calibration curve.

Blood sugar value measuring method and apparatus

Disclosed is a quantitative evaluation method of optical absorption image which applies rays of light to a sample to obtain a quantitative optical absorption image without using destructive inspection and which can measure automatically and easily the dispersion of resistivity of the sample by calculating the mean value and standard deviation of the quantitative optical absorption image.
