Snapshot High-resolution Hyperspectral Imaging

Traditional digital cameras are comprised of an image sensor, typically either a Charge-Coupled Device (CCD), or, more commonly Complementary Metal-Oxide Semiconductor (CMOS). In either case, these devices integrate an array of photodiodes which convert photons to current which is then integrated...

Round Lens. Square Pixels. Accurate Images. Really?

Alens is cylindrical. It captures light in a circular plane for collection onto a rectangular digital sensor plane. This collection of photons is then transformed into electricity by smaller square pixels. Just how do these disparate shapes work together to provide usable images?

How Metal 3D Printing is Redefining Part Design

It's one of the basic rules of manufacturing: As part complexity increases, so do machining and assembly costs. But what if there were a different way to produce metal parts — one with fewer limitations than traditional milling, turning, and grinding processes, and able to build complex parts in...

Sizing and Selecting Linear Motion Systems

Virtually all manufacturing processes incorporate some type of linear motion. A common mistake that designers make when sizing and selecting linear motion systems is to overlook critical application requirements in the final system. This can lead to redesigns, and may also result in an over-engineered...

Piezo Technology in Pneumatic Valves

Pneumatic valves made with piezo technology offer many advantages. They are small, lightweight, extremely precise, durable, fast, and save energy. Piezo valves do not need energy to maintain a switching status, and therefore generate almost no heat. What's more, piezo valves can potentially be operated...

Adding Simple Vision Systems to Collaborative Robots

Adding vision to a collaborative robot can open a world of possibilities for automation applications. With a vision system, a robot can inspect parts, check specific features of a part, recognize a part to pick it up, count items, adjust its path using visual feedback, color sort, and so on....
