# New Products: March 2017 Photonics & Imaging Technology

#### Near Eye Displays Test System

A new test system from Gamma Scientific (San Diego, CA) offers high spatial resolution color and contrast measurements for near eye displays (NED), such as virtual reality (VR) and augmented reality (AR) headsets, and heads up displays (HUD). The Gamma Scientific NED Measurement System incorporates compact imaging optics which feed both an integrated camera viewing system and a low-noise, high-accuracy spectroradiometer.

# Product of the Month: March 2017

Watlow, St. Louis, MO, introduced the D4T with INTUITION® data logger with a range of field-removable I/O modules. The data logger features a 4.3” color graphical touch panel with a high-resolution graphical user interface that allows channels, alarms, inputs, and outputs to be customized with user-defined names. The unit is programmable to show information in multiple languages, and enables users to choose encrypted, .CSV, or both types of file formats for tamperproof record needs. Users can select which parameters to log, from one to 128 points simultaneously, and where to store files — inside the controller, on a connected USB memory device, or to a connected PC anywhere in the world. The system records as fast as one time per 0.1 second, or as slow as one time per hour. The system is available with 1 to 24 channels, and is compatible with temperature, altitude, humidity, AC current, and other 0-10VDC or 0-20 mA process units. It connects with a controller via Ethernet, and offers communications options including Ethernet Modbus® TCP and SCPI, and EIA-232/485 Modbus® RTU.

# New Products: March 2017 Sensor Techonology

#### Shape Sensor

OFS, (Norcross, GA) has developed a shape sensor fiber. The technology platform produces twisted multicore optical fiber with continuous FBGs (Fiber Bragg Gratings). The sensor meets 3D shape sensing specifications, such as twist rate, coating concentricity, grating reflectivity, and grating spacing. Continuous gratings are written without stripping and recoating the fiber.

High-power (multi-kW) fiber lasers are revolutionizing industrial materials processing markets by offering an unmatched combination of performance, reliability, and cost advantages. For example, in sheet metal cutting (the largest application, with more than $1B/year of laser sales), fiber lasers provide the highest cutting speed (especially for thin sheets, the dominant application), scalability to thick sheets (>1”), and the ability to process a wide range of metals with a single tool. Along with low power consumption and high reliability, these capabilities result in the lowest cost per part. Fiber lasers have thus been the fastest-growing segment of the laser market for the past decade.

You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

Analysts from the San Francisco, CA-based business consulting firm Grand View Research spoke with P&IT about current camera technology's most exciting capabilities, applications, and leaders.

Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than$10.8 billion by 2021, up from just \$2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.

# CERTIFICATES AND SIGNATURES: How to Ensure Authentication in the IoT

On October 21, 2016, the Internet saw a significant distributed denial of service (DDoS) attack, conducted via a botnet comprising many co-opted Internet-connected devices. The attackers of the network infrastructure were able to control these Internet-of-Things (IoT) devices for a number of reasons, including a lack of strong authentication. Loaded software turned the machines into puppets that interfered with Internet traffic for millions of users.
