    Laser Sensors | KEYENCE America

    Laser Sensors are used for detecting presence based on position or light intensity. Benefits include long range, a visible beam spot and precise detection. However, technologies such as Laser Detection And Ranging (ladar), lidar, Sound Navigation And Ranging (sonar), Ground Penetrating Radar (GPR), infrared imagery, and gyroscopy, when used in combination with conventional technologies, produce a fairly accurate account of pipe dimensions and sediment depth [12,49]. Underground tunnels and power ...

    Inertial measurement unit - Wikipedia

    An inertial measurement unit works by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. Some also include a magnetometer which is commonly used as a heading reference. Typical configurations contain one accelerometer, gyro, and magnetometer per axis for each of the three vehicle axes: pitch, roll and yaw. The difference is that the magnetron in a radar has to send the waves many miles, instead of just a few inches, so it is much larger and more powerful.

    measuring the time delay between transmission of a pulse and detection of the reflected signal. •The primary difference is that with LIDAR, much shorter wavelengths of the electromagnetic spectrum are used, typically in the ultraviolet, visible or near infrared, making it possible to image much smaller features (1000x). LIDAR-Lite fills that gap by stuffing an entire LIDAR module onto a small board. In traditional LIDAR systems, a laser is used to measure the time of flight for a light beam between the sensor and ...

PROCEEDINGS VOLUME 9494 Next-Generation Robotics II; and Machine Intelligence and Bio-inspired Computation: Theory and Applications IX Because dark noise typically drops to half when the temperature of the CCD detector chip drops every 10°C, the difference between a room-temperature hand-held at 25°C and one cooled to -15°C is 16X lower dark noise that translates into 12–16X better sensitivity.

    Radar Basics

    Between 8 and 12 GHz, the ratio of wavelength to antenna size has a more favorable value. With relatively small antennas, sufficient angular accuracy can be achieved, which favours military use as airborne radar. On the other hand, the antennas of missile control radar systems, which are very large relative to the wavelength, are still handy ...
