Title: Reflection type photosensor
Inventor: NAKAMURA TETSUO
IPC: G01S7/48
Filed: 1984-12-02
Abstract: PURPOSE:To exactly detect a position of an object of a different reflection factor by providing a light emitting element, a photodetector and a housing, and forming an optical path of the housing to a recessed shape optical path. CONSTITUTION:Among the lights of a light emitting diode 12 loaded on a housing 11, a light 20 going to a window 17 advances toward a detecting object, but lights 18, 19 which have been turned aside a little are shut up in an optical path 14 because the optical path 14 is formed in a recessed shape, scarcely emitted from the window 17, and even if they are emitted, many reflections are repeated and an intensity of the light becomes extremely weak, and it is not detected by a phototransistor. Also, the photodetecting side is the same, too, a light 10 which has gone straight on toward the phototransistor from a window 16 arrives at the phototransistor, but an oblique light 26 repeats a reflection by a recessed shape optical path 15 and does not arrive at the phototransistor easily, and even if it has arrived, it becomes a sufficiently weak light. By constituting the recessed shape optical path in this way, a position can be detected exactly and stably even in case of an object whose reflection factor is different remarkably.

Title: Method and apparatus for measuring thickness of corneous layer
Inventor: SURIDOHARU GORUTEI
IPC: A61B5/107
Filed: 1990-09-25
Abstract: PURPOSE:To enable accurate measurement with high applicability for skin of any kind with accompanying inflammation and pains by a method wherein a intensity distribution of a reflected light is determined based on a detection signal to be processed as thickness data of a corneous layer and the thickness of the corneous layer is measured from the data. CONSTITUTION:A case 11 is set on the surface of a corneous layer SC roughly 20mum thick of a human body. A computer 4 is operated to make a laser light with a wavelength of 632.8nm irradiate the corneous layer SC from a semiconductor laser 1 while the reflected light reflected from the corneous layer SC is converted into an electrical signal with a photo-diode array to be amplified with a signal amplifier 3 and after digitized with a A/D converter 7, it is processed with the computer 4. As a result, an intensity distribution of the reflected light is determined to be processed as thickness data of the corneous layer and a total thickness of the corneous layer can be determined from the data. Thus, when the keratin layer SC is measured with the irradiation of the laser light, this method can be applied to the measurement of the thickness of the corneous layer of any kind not limited to that becoming morbid. This is very safe without possible damage to skin.
