Patent number: 8773668Abstract: A signal processing unit (C1, C2, C3) for processing a light reception signal from an imaging element (12) at different magnifications is provided in a light receiving unit (102) in a displacement sensor (1). This sensor (1) measures a displacement by using light receiving amount data generated by the signal processing unit (C1) for each detection processing by a light projecting unit (101) and the light receiving unit (102), and further adjusts sensitivity for next detection processing. In sensitivity adjustment processing, when a peak value in the light receiving amount data generated by the signal processing unit (C1) approximates to 0, a peak value extracted by the signal processing unit (C2) to which higher magnification is applied is employed. Alternatively, when a peak value in the light receiving amount data generated by the signal processing unit (C1) is saturated, a peak value extracted by the signal processing unit (C3) to which 1-fold magnification is applied is employed.Type: GrantFiled: March 17, 2011Date of Patent: July 8, 2014Assignee: OMRON CorporationInventors: Yusuke Iida, Hiroaki Takimasa

Publication number: 20100232650Abstract: In a measurement apparatus, higher-quality measurement is realized in measurement of measurement object displacement or imaging of a two-dimensional image. In a controller, a light receiving signal of a photodiode is supplied to a displacement measuring unit of a sensor head in order to measure a height of a measurement object, and the height of a surface of the measurement object is measured based on the light receiving signal. Then, in the controller, image obtaining timing is determined based on the height of the measurement object. Specifically, a focus adjustment value corresponding to the computed height of the measurement object is obtained from the table, and an image obtaining signal is transmitted to an imaging device at the timing the focus adjustment value is realized. Therefore, a length between two points on the measurement object is computed from the thus obtained image based on the height of the measurement object.Type: ApplicationFiled: February 25, 2010Publication date: September 16, 2010Inventors: Yoshihiro KANETANI, Takahiro SUGA, Hiroaki TAKIMASA, Naoya NAKASHITA, Yusuke IIDA
