摘要： PURPOSE:To obtain a background beam signal through an optical filter, correct a position detection signal, and detect displacement with high accuracy when the displacement of the reference surface of an object is detected by irradiating the object with laser beam for measurement and making scattered light incident on a position detecting element. CONSTITUTION:The object W1 is irradiated with beam from a laser beam source 4 for measurement and its scattered beam is made incident on the position detecting element A7. Further, the position detecting element B7 is provided to photodetect beam passed through the optical filter 20 which transmits beam except beam having the wavelength of the laser beam for measurement. This element B7 photodetects only background beam. Then, the displacement detection signal from the element A7 contains the background beam signal, so inverse operations 18 and 19 of the signal are carried out with a signal base upon only the background beam from the element B7 to remove the background beam signal from the displacement detection signal. For the purpose, only the background beam is passed through the optical filter to remove the background beam signal from the displacement beam signal, so the displacement of the object is detected with high accuracy.
摘要翻译：目的：通过光学滤波器获得背景光束信号，校正位置检测信号，并通过用激光束照射物体来检测物体的基准面的位移，并以散射光进行检测，高精度地检测位移事件发生在位置检测元件上。构成：物体W1用来自激光光源4的光束照射测量，其散射光束入射到位置检测元件A7上。此外，位置检测元件B7被设置为对通过光学滤波器20的光束进行光检测，该滤光器透射具有用于测量的激光束的波长的光束。该元件B7仅对背景光束进行光电检测。然后，来自元件A7的位移检测信号包含背景光束信号，因此信号的反向运算18和19仅以来自元件B7的背景光束的信号为基础，以从位移中去除背景光束信号检测信号。为此，只有背景光束通过滤光器才能从位移光束信号中去除背景光束信号，从而高精度地检测物体的位移。

摘要： PURPOSE: To detect the displacement with high precision by eliminating the background light voltage from the displacement detection voltage in distance measuring instruments measuring the displacement from a datum plane of an object.
CONSTITUTION: Light is projected on a lens 3 from a semiconductor laser 2 and the object surface W1 is irradiated with the spot light. The light is reflected on the surface W1 and made incident on a displacement detecting element 1 via a lens 4. Displacement detection electric currents Ia, Ib of the detecting element I by the displacement ΔH of height of the surface W1 are converted into displacement detection voltages Va, Vb with an I/V converter 6. At this time, since the background light is generated from the object surface W1, background light sampling circuits 15, 16 detecting this background light only are connected with opposite phase adders 17, 18. Then, the background light voltage is added to the opposite phase adders from the displacement detection voltages Va, Vb and the background light voltage is eliminated from the displacement detection voltages to detect the displacement. Accordingly, since the background light voltage is eliminated from the displacement detection voltages, the displacement of the datum plane of the object surface can be detected with high precision by the distance measuring measurements.

摘要： PURPOSE:To execute precise laser working such as laser cut, etc. by providing a distance control means for controlling so that a distance between a working work and a working lens is kept constant. CONSTITUTION:A radiant beam emitted from a light source 7 is focused by a projection lens 8, and irradiated as an optical spot at the same position as a laser beam 1 on a work surface of a working work W. A photodetecting lens 9 executes an image pickup of the optical spot on the work surface, and forms an image of the optical spot on a photodetecting surface of a photodetector 10. The photodetector 10 which has detected this optical spot image generated an electric signal corresponding to an image formed position of the optical spot image. A processing circuit 11 executes an operation and sends out a distance output. That is to say, an electric signal for controlling the position of a working use lens 2 is outputted so as to keep a distance l constant. Accordingly, the position of the lens 2 is adjusted, and the distance between the work surface of the working work W and the lens 2 of a working head 20 is controlled so that it always becomes constant.
