Thermal Imaging’s Pocket-Sized Potential

Let’s say you’re a prospective buyer touring an older home that you suspect has some weatherization issues. What if you could verify your hunch by literally seeing cold air seeping under doors or cooling walls where insulation is missing? And what if you could do this on the spot using a smartphone?

Camera Considerations When Inspecting Printed Circuit Boards

PCB manufacturing is a very competitive market, and manufacturers must be able to confidently ship accurate printed circuit board (PCB) products. Delivery of incorrect boards may have a significant, negative impact on the company reputation, which can directly result in lost business. Inspection of the boards before shipment is required.

NASA's Hot 100 Technologies: Instrumentation

Powder Handling Device for Analytical Instruments This technology provides automated sample handling and movement of coarse-grained powder or other solid materials to enable analysis by a robotic or totally automated computer system. The powder is handled as a fluid, using mechanical vibrations in conjunction with a driving force, and requiring few or no moving parts.

NASA's Hot 100 Technologies: Optics

Automated Vision Test The traditional test for visual acuity requires the patient to look and report which letters they see. A new invention provides an automated system to estimate visual acuity based on objective measurements of the eye optics and wavefront aberrations. A typical measurement consists of a list of numbers that constitute the coefficients of the polynomials. The algorithm converts the list of numbers into an estimate of the visual acuity of the patient.

Prepping Advanced Driver Assistance for Mainstream Vehicles

Forward-facing cameras, integrated with vehicle controls, are being used to recognize pedestrians, signs, and other cars and motorcycles. Automatic brake mechanisms — often connected to a combination of radar, camera, and sensors — can halt a vehicle as it approaches an object ahead. New mounted cameras have the ability to register road markings and keep drivers within their own lanes.

Blurring the Boundaries: IP and Machine Vision Cameras Converge

In modern production facilities, users are more frequently combining two different strands of camera technology. Classic machine vision cameras manage inspection tasks and yield management, while network cameras (also called IP cameras) handle process monitoring and bringing production to a standstill when necessary.

Defining the Smart Camera

Smart cameras have been used in industrial applications for roughly two and a half decades, but advances in processor technologies have made the devices much more accessible and popular within the past 7 years, especially in areas such as machine vision and surveillance. However, when the term smart camera is mentioned, a wide variety of ideas still come to mind among individuals because there is no widespread agreement upon the definition of what a smart camera technically is. It is generally agreed upon that the basics of a smart camera include not only the image sensor, but also some type of processing chip: a CPU, DSP, FPGA, or other type of processing device (see Figure 1).

Measuring Motion with Imaging Software

High-speed photography is as much of an engineering tool as an oscilloscope, spectrum analyzer, or logic analyzer. The photographic technique enables us to visualize and analyze motion, especially motion that is too fast for the human eye or conventional cameras to perceive.

3D Visualization Technologies: Seeing a World of Opportunity

Industries as diverse as architecture, engineering, construction, advertising, and medical have all incorporated an array of 3D visualization technologies into their design, development, and production processes. A rapidly expanding library of 3D modeling tools, 3D content, and 3D printing materials have made design more cost-effective and expedited the product-to-market process. But how exactly do 3D visualization technologies work? Taking a closer look at the science behind the innovation reveals a striking convergence in which state-of-the-art research processes meet a growing understanding of visual communication.
