Part 1 looked at various uses of X-ray technology as well as ultrasound imaging. Cameras are an essential part of many medical diagnostics as well. The lining of the esophagus, stomach, and first part of the small intestine are examined using Esophagogastroduodenoscopy (EGD). In this procedure, the scope (a video camera with light) is inserted through […]
How do surgeons navigate inside a patient’s body? Part 1 of 2
Until the invention of X-ray technology, doctors had no way of determining what was happening inside a patient without the use of surgical tools. X-ray still is one of the first steps toward identifying many body ailments. However, determining if a blockage, restriction, stone, hemorrhage, cancer or other abnormality is present also involves many other […]
Optical sensors for longer operating distances
With the R200 and R201 designs, the product design of photoelectric sensors from Pepperl+Fuchs enables applications with longer operating distances. Just like the compact R100, R101, and R103 series, both new products consistently offer all photoelectric functional principles in a design that is now larger and suitable for specific mounting situations. Usability is intuitive and […]
What do you get when you combine 3D scanning and computed tomography (CT)?
If you are in the field of analyzing ancient Egyptian mummies, something really cool and informative. In the Sherit mummy project, researchers benefited from adding the results from a 3D scanner to a CT scan. Sherit is a mummified Egyptian child who died 2,000 years ago. Even though the Rosicrucian Egyptian Museum in San Jose, […]
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 […]
High-speed streaming camera from Vision Research offers record-breaking data transfer
Vision Research has introduced the Phantom S990, which it is reporting is the world’s fastest machine vision camera. The S990 features the right combination of fast frame rate, high resolution and available throughput for use in demanding machine vision applications in multiple industries. The camera combines high-speed image quality with record-breaking direct data transfer speeds […]
What do the latest imaging systems in airborne objects reveal? Part 2
Archeological searching is being conducted from above at altitudes well below those of satellite orbits. One group of researchers has used an airborne laser scanner (ALS) mounted to a helicopter’s skid pad to reveal several cities between 900 and 1,400 years old beneath the tropical forest floor in Cambodia. The first LiDAR (light detection and […]
What do the latest imaging systems in airborne objects reveal? Part 1
Advances in the vision systems in orbiting satellites are revealing ancient pyramids in the desert sands of Egypt, the ruins of hidden temples and cities in the jungles of South America, Cambodia and other areas and even man-made structures under water in oceans and lakes. Satellites with imaging systems that can see through clouds and […]
What functions do sensors provide to drones?
Depending on the type of drone and its function, there can be a few essential sensors or an extensive number of sensors on board. Whether the drones are civilian or military craft, the sensors fall roughly into three categories: Make Them Fly, Make Them Work and Diagnose & Prevent Problems. Make Them Fly An inertial […]
How can touch-free sensing protect public health?
Many communicable diseases, such as viruses and bacterial infections, are transmitted by direct contact with a person who has the disease or with something that person touched. Avoiding contact is an obvious way to prevent spreading diseases. Touch-free sensors allow many frequently accessed functions in restrooms, such as automatic hands-free urinal and toilet flush, hands-free […]
