Abstract: A sheet discriminator, which can be included in an image forming apparatus, includes an optical information detector, a sheet distinguisher, and a sheet thickness detector. The optical information detector includes a light emitter to emit light to a recording medium and a light receiver to receive the light and detects information of the recording medium. The sheet distinguisher distinguishes a type of the recording medium based on the information detected by the optical information detector. The sheet thickness detector includes a displacement gauge to sandwich the recording medium with an opposing member disposed facing the displacement gauge and to move from an initial position thereof and a displacement detector to detect an amount of displacement of the displacement gauge. The sheet thickness detector detects a thickness of the recording medium based on detection results obtained by the displacement detector.

Abstract: An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.

Abstract: A method capable of quantitatively evaluating the intensity of scintillation caused by surface unevenness. Light from a white light source is made incident on a surface of an object to be measured through a matrix filter. Reflected light or transmitted light from the object is photographed with a CCD camera and taken into a computer as data. Image processing for the luminance distribution of the captured light is performed to obtain a standard deviation of dispersion of the luminance distribution. The value of the standard deviation obtained is defined as a scintillation value of the surface of the object. The performance of the object is evaluated by judging whether or not the scintillation value is greater than a predetermined value

Abstract: In a coated or uncoated film, variations in thickness as well as all possible casting errors may be dependably determined and evaluated, in that two light sources transmit modulated IR light wherein the modulation frequencies are different, wherein one light source transilluminates the film, while the other light source is arranged on the other side of the coating carrier, illuminates the latter obliquely and both the transilluminating and the reflected light bundles are conducted to a photo-receiver. The current signal arising in the photo-receiver is transformed into a current signal, amplified and feeds two electronic filters circuited in parallel, which free the signals from their modulation frequency, after which both signals are separately rectified. Subsequently the signal originating from the transmitted light portion is delogarithmized and forms a statement concerning the thickness of coating, while the light originating from the reflected portion evaluates surface errors. In this manner a separate evaluation of both kinds of error is possible.
