Identifying Resolution of Imaging Systems Resolution is a measurement of an imaging system’s ability to resolve the object which is be imaged. Test targets are typically tools that are used to check the resolution of an imaging system. The most popular targets consist of “groups” of 6 “elements” and each element consists of three horizontal […]
Design for Manufacturing (DFM) Case Study: Objective Lens Design for Trapping and Imaging Single Atoms At Avantier we offer Design for Manufacturing (DFM services), optimizing product design with our extensive knowledge of manufacturing constraints, costs, and methods. Avantier Inc. received a request from a University Physics department to custom design a long working distance, high […]
Today’s advanced driver assistance systems take advantage of AI-spiked cameras and radar or sonar systems, but most manufacturers have been waiting for advances in machine vision technology to go one step further into autonomous self-driving cars. Today, that technology is ready to roll out. We call it LiDAR: Light detection and ranging. LIDAR in autonomous […]
How Peak to Valley (PV) and Root Mean Square (RMS) Affect the Quality of Your Optics Just how smooth is the surface of your optic? Qualitative descriptions are of limited value, and often you’ll want to put a number to it. Two ways of quantifying deviations from an ideal optical surface are peak-to-valley (PV) and […]
A microscope is an optical device designed to magnify the image of an object, enabling details indiscernible to the human eye to be differentiated. A microscope may project the image onto the human eye or onto a camera or video device. Historically microscopes were simple devices composed of two elements. Like a magnifying glass today, […]
For storage and transmission of large image files it is desirable to reduce the file size. For consumer-grade images this is achieved by lossy image compression when image details not very noticeable to humans are discarded. However, for scientific images discarding any image details may not be acceptable. Still, all the images, except completely random […]
Image Analysis of a 3D Image Several manufacturers sell 3D cameras which use 2D sensor arrays sensitive to the phase of reflected laser light. All of them spread laser light so that it permanently illuminates the complete scene of interest. Laser light is modulated synchronously with the pixel sensitivity. The phase of reflected laser light, […]
Let’s look at the transportation industry-based case of extensive image processing. Two video cameras were looking at the boxes moving fast on the conveyor belt. To provide high enough image resolution the cameras were placed close to the belt but they could not cover all the belt cross-section. They were placed on the sides of […]
At Avantier, we are our proud of our track history in assisting customers to solve problems using reverse optical engineering. Here are three case studies. Case Study 1: Reverse Engineering an OFS 20x APO Objective Lens for Bioresearch Genetic engineering requires using precision optics to view and edit the genomes of plants or animals. One […]
