In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1. At one...Photonics HandbookMachine Vision Cameras: Making the Right Selection: Improvements and affordability have broadened the use of vision systems for inspection, but several factors should be considered before making a purchase.Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before. These factors...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...WHITEPAPERSPhotonics.com 1/14/2021Fractional Pixel Method for Improved Pixel-Level Measurement and Correction (Demura) of High-Resolution DisplaysAs display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during...Photonics.com 1/14/2021Methods for Measuring Display Defects and Mura as Correlated to Human Visual PerceptionHuman vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production...Photonics.com 1/14/2021Automated Solutions for SAE Standard HUD MeasurementHead-up display (HUD) technology is one of the largest growth areas in the automotive market, and standard measurement criteria are rapidly being defined to evaluate augmented projections for visual...Photonics.com 1/14/2021Using Imaging Colorimeters to Correct OLED, MicroLED, and Other Emissive Displays for Production Efficiency and YieldsImaging colorimeters can improve OLED and microLED display production by ensuring visual quality of displays — measuring brightness and color uniformity at the pixel and subpixel level to correct...WEBINARSPhotonics.com 6/5/2013Computational Microscopy, Sensing and Diagnostics for Telemedicine and Global Health ApplicationsAdditional Questions and Answers from the Webinar are below: With more than 6 billion cell phone users in the world, the majority of them in developing countries, there are opportunities for...Photonics.com 6/11/2015Biophotonic Imaging for Medicine: A Digital ConferenceResearchers from around the world presented their latest work at “Biophotonic Imaging for Medicine: A Digital Conference.” Presentations focused on a range of light-based imaging and...Photonics.com 5/29/2013Developments in Optics and Optical ComponentsFree Webinar Additional Questions & Answers from the Webinar below: Speakers: Dr. Robert R.
