A target detecting device projects measuring light over a predetermined range in front of a vehicle, receives reflected light from a target, and detects the target or a distance to the target, based on a light reception signal output according to the light reception state. The light projecting unit includes a light emitting element emitting measuring light and light diffusion members. The light diffusion members are provided on an upper end portion and a lower end portion of a light projecting lens constituting part of a light projecting path, and diffuses, in the vertical direction, measuring light emitted from the light emitting element and traveling through the end portions in the vertical direction of the light traveling path while transmitting the measuring light.

Target detecting device

A projection optical system includes a laser diode; a laser diode module having a plurality of the laser diodes one-line arranged; a light projecting lens to adjust spread of light emitted from the respective laser diodes; and an optical deflector to deflect light passing through the light projecting lens and irradiate a target with the deflected light. The laser diodes emit light such that the light spreads at a first angle in a first direction and spreads at a second angle being wider than the first angle in a second direction being perpendicular to the first direction. The laser diode modules are disposed such that an arrangement direction thereof coincides with the first direction and they are placed along the second direction and shifted in position relative to each other in the first direction. The light projecting lenses are disposed with corresponding to the laser diode modules.

Projection optical system and object detection device

An object detection device includes a first substrate with a laser diode thereon; a second substrate with a photodiode thereon; a holding member holding the first and second substrates; an optical deflector deflecting light projected from the LD to irradiate a target with the deflected light, and deflects light reflected off the target; and a reflecting mirror guiding the reflected light deflected by the optical deflector to the PD. The LD is mounted on a mounting surface of the first substrate to project light mainly in a direction parallel to the mounting surface. The PD is mounted on a mounting surface of the second substrate to receive light coming mainly in a direction perpendicular to the mounting surface. The holding member parallelly holds the first and second substrates such that projection planes of the first and second substrates perpendicular to the mounting surfaces overlap each other.

Object detection device

Teaching processing using a model of a workpiece is performed by accepting at least one input of a target value for a response time and a tolerance value for a detection error as a parameter representing a condition for a displacement sensor to operate. A CPU during teaching processing determines a maximum exposure time while it causes repeated detection processing by a light projecting unit and a light receiving unit, calculates variation in measurement data of an amount of displacement, and derives the number of pieces of data of moving average calculation suitable for a value for the input parameter as a result of operation processing using the maximum exposure time and variation in measurement data. This number of pieces of data is registered in a memory and used for moving average calculation in a normal operation mode.

Displacement sensor

A radio detection device includes two or more reception antennas, for detecting a detecting object by a mono-pulse method; the radio detection device including: a variable gain unit for discretely changing respective signal intensity of a difference signal and a sum signal of each reception signal received by the two or more reception antennas; an A/D conversion unit for performing A/D conversion process on the difference signal or the sum signal, the difference signal or the sum signal having the signal intensity changed by the variable gain unit; an angle calculating portion for calculating an angle by the mono-pulse method using the difference signal and the sum signal after the A/D conversion process by the A/D conversion unit; and a control unit for performing a control of individually switching a conversion magnification of the signal intensity by the variable gain unit with respect to the difference signal and the sum signal.

Radio detection device and method

A radar device for detecting an object in front of the radar device, has a plurality of antennas, wherein the object is detected based on each reception signal received by two or more of the plurality of antennas, a position specification section for specifying a position of the object by using each reception signal received by the two or more of the plurality of antennas; and an object detection section for confirming an existence of the object if the position specified by the position specification section is in a predetermined range.

Radar device and radar method

A measuring apparatus for measuring a distance from an object to be measured has, a transmitting means for alternately modulating amplitudes of a first continuous wave having a first frequency and a second continuous wave having a second frequency for transmitting a transmission signal as a carrier wave using an AM signal. The AM signal is produced by an AM producing circuit for modulating the amplitudes. The transmission signal is reflected as a reflection signal by the object to be measured and received by a receiving circuit. A first distance calculating circuit calculates the distance using a phase difference between the first and second continuous waves. A second distance calculating circuit is used for demodulating the receipt signal, detecting a phase difference, and calculating a distance from the object to be measured using the detected phase difference. A determining circuit determines a final distance measurement based on the above calculations.
