摘要： PROBLEM TO BE SOLVED: To provide a stationary wave distance sensor which can measure the distance to an object to be measured when it is in the stationary state and estimate a position at which the object to be measured will arrive after a lapse of predetermined time when it is on the move stably and with high precision.
SOLUTION: The stationary wave distance sensor comprises a transmitter for transmitting a transmission wave while sweeping the frequency of the transmission wave and a detection means for detecting the amplitude intensity of a stationary wave formed between the transmitter and the object to be measured, measuring the distance from the transmitter to the object to be measured. The transmitter sweeps the frequency of the transmission wave. A distance estimation means is provided which converts the relationship of the amplitude intensity of the stationary wave with the swept frequency into the relationship of the amplitude intensity of the stationary wave with a distance detected by the Fourier transform and estimates that a distance corresponding to a peak of the amplitude intensity of the stationary wave is a distance from the transmitter to the position at which the object to be measured will arrive after a lapse of predetermined time.

摘要： PROBLEM TO BE SOLVED: To reduce the size of an optical position detector by providing a condensing means and an imaging means constituted of a planar waveguide on a same substrate. SOLUTION: A luminous flux introduced from an input optical fiber 104 to a planar waveguide (condensing means) 103 propagates while being confined in the Y-axis direction and being dispersed in the Z-axis direction depending on the numerical aperture of the fiber. It is reflected on the curved end face 106 of the planar waveguide and delivered from the outgoing end face 107 before being focused at a desired measuring point on a plane 110 to be detected. A luminous flux reflected on the plane 110 to be detected is introduced from an incoming end face 112 to a planar waveguide (focus means) 111. The luminous flux confined in the Y-axis direction is totally reflected inward on the curved end face 113 of the planar waveguide and the image of a spot on the plane 110 to be detected is separated to respective branch waveguides 114a, 114b depending on the focus position and then the separated states are combined through output optical fibers 115a, 115b and taken out externally. Since the light can be condensed and focused without employing any lens, dimensions of the detector can be reduced.

摘要： PURPOSE:To measure a film thickness with high accuracy without being affected by the inclination of a sample by a method wherein a light path is constituted in such a way that light paths for deflected optical beams are crossed in one point on the face of the sample and a maximum value during one scanning cycle of a beam of light which has been transmitted through, and reflected by, the sample is detected. CONSTITUTION:A beam of light from a light source 1 is converted 2 into a parallel beam, it is then branched 3 into two beams, and one optical beam is incident on a detection element 4 which monitors the intensity of the light source 1. The other optical beam is scanned by a deflecting scanner 5, it is incident on a deflecting mirror 7, it is reflected on many faces, an incidence angle with reference to the face of a sample 8 is changed periodically around 0 deg., and the beam is incident on the sample 8. Thereby, even when the sample 8 is tilted, the incidence angle of the optical beam becomes 0 deg. surely once during one cycle. The intensity of a beam of transmitted light becomes a value reflecting a true film thickness and becomes a maximum value. A peak hold circuit 11 and a divider 12 compute a film thickness value on the basis of the output value of a detection element 10 when the intensity of a beam of light becomes maximum during one cycle.
