摘要： PROBLEM TO BE SOLVED: To provide a light scanning system, a laser radar system, and a light scanning method, wherein the sensitivity is kept constant in a full range of a wide-angle visual field region.
SOLUTION: In scanning a laser beam through a transparent flat plate that is arranged to intersect at a predetermined inclination angle relative to the horizontal direction, the laser beam emitted from a light source is scanned in the horizontal direction, while a polarized surface of the laser beam emitted from the light source is rotated depending on the inclination angle of the transparent flat plate and the horizontal directional azimuth to output the polarized laser beam to the transparent flat plate side for scanning with the laser beam through the transparent flat plate.

摘要： PROBLEM TO BE SOLVED: To provide a distance measuring apparatus in which a reflection wave arriving from a target that reflects a transmission wave can be detected more accurately.SOLUTION: In a distance measuring apparatus, a cycle signal representing a measurement cycle Tcycl is generated and a transmission timing signal ST composed of N pieces of pulse signals is generated synchronously to the cycle signal, thereby transmitting laser light. In such a case, the pulse signals are outputted at time intervals Tw sufficiently longer than the time required for laser light to reciprocate a maximum detection distance of the apparatus. An A/D converter 32 then samples the N pieces of pulse signals at predetermined sampling intervals, and an adder 33a adds sampling values which are sampled at the same time with the transmission timing of each transmission wave as a criterion within a plurality of measurement terms Ts and pre-transmission terms Tb in the time intervals Tw. A distance measuring section 33 then refers to all the sampling values in the plurality of pre-transmission terms Tb and sets a detection threshold required for detecting a reflection wave of laser light.

摘要： PROBLEM TO BE SOLVED: To provide a driving support device which is user-friendly while suppressing wasteful operations.SOLUTION: When start/stop processing is started by a driver operating a start switch 171 (a start condition is satisfied), lateral monitoring processing is started and it is notified that the lateral monitoring processing is being operated to the driver via a display device 15 and a transmission device 16 (S110). When surrounding conditions specified by various information correspond to conditions in which monitor is unnecessary (any of stop conditions 1 to 6 is established) (YES in any of S120 to S170), the lateral monitoring processing is stopped and inoperativeness (start/stop) of this lateral monitoring processing is notified to the driver via the display device 15 and the transmission device 16 (S180). Thereby, generation of an alarm based on the lateral monitoring processing in the situation in which the driver does not need the lateral monitoring processing can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a filtering method by which an unnecessary high frequency signal component unable to be eliminated by a digital moving average filter can be attenuated without the need for a CR filter and to provide an analog/ digital converter with a filtering function. SOLUTION: An analog moving average filter 2 is provided to a first stage of the analog/digital converter provided with an analog/digital converter 4 and a high frequency signal component eliminating digital moving average filter 6, and sampling frequencies of the filters 6, 2 are set to be fsd=n×fsa (n is a positive integer: 1, 2, etc.). As a result, an unnecessary signal pass band from the filter 6 appearing at frequencies of a multiple of n of the sampling frequency fsd is overlapped with a region with an infinite attenuation appearing at frequencies of a multiple of n of the sampling frequency fsa at the filter 2 and the entire device can efficiently attenuate the unnecessary high frequency signal component. Further, the similar effect can be obtained by using a temporal analog/digital converter in place of the analog moving average filter 2 and the analog/digital converter 4.

摘要： PROBLEM TO BE SOLVED: To provide a technique that can restrain, for a distance measuring device that measures the distance to an object having reflected a light wave emitted from the device itself, incidence of ambient light even where a highly sensitive light receiving element is used for a light receiving unit.SOLUTION: A radar controller so exercises control, after emission of a light wave by a light emitting unit, as to let the light wave come incident on a light receiving unit only during a period in which reflected waves within a prescribed measuring range can be detected (S220, S230, S250 and S260); the radar controller calculates the distance to an object having reflected the light wave on the basis of an output from the light receiving unit (S240); a radar device having such a configuration can prevent the light receiving unit from letting the light wave come incident except during the period in which the reflected waves within the prescribed measuring range can be detected; therefore, incidence of ambient light can be restrained without restraining the luminous energy of the reflected light, and the distance to the object can be measured satisfactorily.

摘要： In an A/D conversion apparatus comprising an A/D converter (4) and a digital moving average filter (6) for removing high-frequency signal components, there is provided an analog moving average filter (2) at a first stage. A sampling frequency of the filters (6 and 2) is set to fsd=nxfsa (where n is a positive integer of 1, 2, ---). As a result, it becomes possible to superimpose an unnecessary signal passing area that appears at every frequency of n times the sampling frequency fsd in the filter (6), on an area of infinite attenuation that appears at every frequency of n times the sampling frequency fsa in the filter (2). In the apparatus as a whole, it becomes possible to efficiently attenuate unnecessary high-frequency signal components. It is also possible to obtain a similar effect when a time A/D converter is used in place of the analog moving average filter (2) and the A/D converter (4).
