Optics How-to: The Makings of a Successful Imaging Lens

2019-01-26
Imaging and machine vision technology is under more pressure than ever to meet the increasingly demanding needs of a diverse set of markets, and truly understanding imaging is becoming quite the valuable skill. The first part of this article series reviewed how to create a specification to meet your application need and finding the proper balance between cost, development time, system size, and weight. In part two, we reviewed how those earlier decisions translate into a design and the possible trade-offs between performance-based specifications that could be required. Finding balance between the perfect nominal design and a design that can be manufactured is critical. Finally, in this article we will cover lens testing methodology and creating alignment between validating your desired performance and your suppliers production and testing processes.

SETTING EXPECTATIONS DURING TESTING

Once you have your final lens design, it is critical to set proper expectations with your supplier about everything that will happen next before you cut the orders for prototypes or production units. In the earlier parts of this series, we saw that there are many details required to create your full lens specification. The specification document for your project could be 50 or 100 entries long. What is your expectation about testing every line in that matrix? Do you actually desire or require testing on only a few critical parameters? Do you want detailed, highly granular testing reports, or is pass/fail data sufficient? Is the testing methodology, philosophy, and equipment utilized important to end goals?

Taking the time to answer these questions now can prevent issues and delays from occurring later. Make sure you and your supplier have a detailed, written understanding of how you will both validate that the supplier delivered what you both agreed to at the end of the design process…

Students Schooled on Careers in NDT and Manufacturing

2019-01-26
Current worker shortages nationwide have begun changing community conversations about the future of the next generation and the value of trade-based occupations, according to Kate Lufkin with the Kalispell Chamber of Commerce. On Wednesday, Flathead High School sophomores, juniors and seniors got the opportunity to explore some of those trades through hands-on learning with professors at Flathead Valley Community College and tours of local businesses.

Dubbed “Pursuing the Trades,” the event, organized by Lufkin, Mike Kelly of the Flathead High School Career Center and the Occupational Trades Department at FVCC, offered an educational first look at some potential careers for the students selected to attend.

“I dare you to look around and find something that wasnt manufactured,” Lufkin said. “You cant do it. Everything has to be made and somebody has to make it.”

Todays job market, according to Lufkin, supports seven trade jobs for every one position that requires a masters degree.

The majority of the students in attendance, according to Lufkin, expressed little to no interest in pursuing a college career, but show aptitude and interest in more vocational skills.

FVCC offered a unique opportunity for those students to learn about some of the training, equipment and real-life applications for trades such as welding, heavy equipment operation and electrical work…

LMI Technologies Launches Next Evolution in 3D Scanning and Inspection

2019-01-26
LMI Technologies (LMI), the global leader in 3D scanning and inspection, is pleased to announce the official release of three new game-changing products. All three were displayed at Vision 2018 in Stuttgart.

Gocator 2500 Smart Laser Profiler Series – Blazing Speed

With dedicated FPGA processing, advanced optics, and a high speed 2.4 MP custom camera, the Gocator 2500 sensors excel at the scanning and inspection of fast-moving parts in a compact, all-in-one industrial package at rates up to 10 kHz. Users can leverage onboard processing for 3D surface generation, 6DOF alignment, part segmentation, and built-in 3D measurement tools for feature extraction and decision making to build a full inspection solutionfrom raw image data to 3D results for 100% quality control. In comparison, “non-smart” sensors have to send profile data downstream to PCs or external controllers to carry out 3D surface generation and apply measurement tools, adding data latency and unnecessary cost and complexity.

Gocator 3504 Smart 3D Snapshot Sensor – Highest Resolution

This stereo snapshot sensor offers point-and-shoot 3D in a compact, industrial form factor that delivers exceptional resolution. The Gocator 3504 leverages a number of technology advancements in order to achieve a high level of performance at 6.7 micron XY resolution with a Z repeatability of 0.2 microns, and an industry-leading speed of 6 Hz (with acceleration)making it an excellent upgrade over traditional confocal or white light interferometry measurement systems.

GoMax Smart Vision Accelerator – The Next Step In Vision Performance

GoMax simplifies how factories achieve inline production speed by leveraging a new breed of computing based on the NVIDIA TX2 Jetson module. Simply add GoMax to a single or multi-Gocator sensor network to dramatically improve overall scan and inspect cycle times. Inside GoMax is a preloaded Linux OS with the Gocator Accelerator (GoX) runtime offering 3D point cloud generation and measurement tool processing optimized for execution on the 256 CUDA cores.

GoMax offers a small form factor and a low power usage of only 15 watts. Plus, setup is quick and easy. Just power up, connect via web browser, and activate acceleration for any Gocator 3D smart sensor to get improved speed.

Introduction to Automated Macro Indentation Testing

2019-01-26
Industrial infrastructure components undergo time-dependent material and property degradation associated with thermomechanical loads (temperature, pressures, dynamic loads) and operating environments (corrosive media, H2) which influences the structural integrity, and in rare scenarios lead to failure. The traditional approach has been to schedule periodic inspections to evaluate defect size, location and statistics which is represented as solid line in bath tub curve.

The emerging trend is to go beyond traditional risk-based inspection (RBI) to knowledge based inspection (KBI) which aims to understand mechanisms and use information to schedule the next inspection, represented by the dotted line in the bath tub curve. The benefit of this approach is an increase in plant availability factor as well as extended operational life beyond design limits.

AMIT (automated macro indentation test) falls in the category of knowledge-based inspection system.

What is AMIT ?

AMIT, automated macro indentation test, is a technique used for in-situ determination of key mechanical properties of components, such as yield strength (YS), ultimate tensile strength (UTS), strain hardening exponent (n), hardness (BHN) and fracture toughness (KIC). This technique was jointly developed by Ducom Instruments in partnership with NML, Jamshedpur.
