How can time of flight technology be used?
At Sensors Expo 2019 in San Jose, CA, Clint Cowan from Laser Technology demonstrates and explains the company’s time of flight laser technology for detection in an intelligent gate and its TruSense S300 sensor for non-contact fluid-level sensing in clear water. With the intelligent gate, if a person is inside of 3 feet, the laser […]
What types of sensors are used in underwater navigation and exploration? (Part 2 of 2)
Underwater navigation and exploration require special sensors for object detection and imaging. Part 1 of this blog addressed cameras and sonar. LiDAR is also used for underwater applications. Studying the depths and shapes of underwater terrain or bathymetry can be performed by bathymetric LiDAR. The airborne approach to scanning the seafloor uses a green wavelength […]
What types of sensors are used in underwater navigation and exploration? (Part 1 of 2)
Unlike land or airborne vehicles that can use radar and cameras to locate and identify objects underwater navigation and exploration present greater challenges. If underwater visibility is good, cameras provide a good source of information. Increasing resolution and the number of cameras are among the improvements that have been made in the recent past to […]
How can sensing help a railroad company manage thousands of miles of track?
Part of the Union Pacific Railroad’s answer is in a Precision Measurement Vehicle (PMV). To develop and improve the company’s infrastructure, the PMV is used to provide accurate locations and detailed descriptions of all facilities that can be seen and measured from the track. Global Positioning System (GPS) data from the PMV provides the location […]
What advanced sensing techniques are used to find lost treasures? Part 5: LiDAR
This series has previously addressed magnetometry, electromagnetic induction , ground penetrating radar and resistivity measurements. LiDAR (Light Detection and Ranging) is another sensing technique frequently used by archeologists and treasure hunters to find objects. While it can be used alone, it is often combined with electromagnetic induction, magnetometry and/or electrical resistivity measurements. LiDAR data analysis […]
What advanced sensing techniques are used to find lost treasures? Part 3: Ground penetrating radar
This series has previously addressed magnetometry and electromagnetic induction. While both of these sensing techniques are frequently used by archeologists and treasure hunters to find objects, they are often combined with ground penetrating radar (GPR) to improve the search results. Compared to other commonly available geophysical methods, GPR is the only one that provides true […]
What cool sensor-enabled products were at CES 2018? Part 6
At CES 2018, exhibit companies displayed many new products for smart homes, smart health, smart cars and more. One of the features that people expect to see in future vehicles is autonomous driving. To go beyond today’s technology demonstrations and be affordable to the masses, automotive suppliers will have to make the sensing technologies more […]
Where can time of flight sensing be used?
At Sensor Expo 2017, Doug Gates, a technical sales manager from Melexis explains the applications for his company’s two-chip semiconductor solution for time of flight (TOF) sensing. Time of flight sensing uses optical, acoustic, electromagnetic or other wave techniques to measure the time that it takes for the source to travel a distance through a […]
Demonstrating Sonar on a Chip
At the MEMS & Sensors Group Executive Conference in Scottsdale, AZ, Dave Horsley, Co-Founder and CTO at Chirp Microsystems demonstrates the capabilities of his company’s sonar on a chip (an ultrasound transceiver and microprocessor in a single 8-pin LGA package). The chip uses time of flight measurements for accurately detecting gesture recognition and proximity while […]
