  1. Understand Noise At The Sub-Nanometer Scale

    Every nanopositioner has a small amount of uncertainty in its position that contributes noise to a measurement. It's important to understand what position noise is and where it comes from in order to know just how accurate the nanopositioner is.

  2. Ultra-High-Speed Thermography

    Recent advances in IR camera technologies, such as fast camera detector readouts and high performance electronics, allow high-speed imagery. This article is part 5 of a handbook by FLIR that discusses the use of ultra-high-speed thermography with IR cameras.

  3. Filters Extend IR Camera Usefulness

    Materials that are transparent or opaque to IR wavelengths present problems in non-contact temperature measurements with an IR camera. In some cases, an IR filter can be placed in the camera’s optical path to overcome these problems. This article is part 4 of a handbook by FLIR that discusses how filters can be used to extend IR camera usefulness.

  4. Getting The Most From Your IR Camera

    Understanding IR camera calibration and corrections help ensure accurate temperature measurements and thermographic mapping. This article is part 3 of a handbook by FLIR that discusses how to get the most out of using your IR camera.

  5. IR Detectors For Thermographic Imaging

    Thermographic imaging is accomplished with a camera that converts infrared radiation (IR) into a visual image that depicts temperature variations across an object or scene. This article is part 2 of a handbook by FLIR that discusses the use of IR detectors in thermographic imaging.

  6. IR Thermography – How It Works

    Although infrared radiation (IR) is not detectable by the human eye, an IR camera can convert it to a visual image that depicts thermal variations across an object or scene. Thermography is accomplished with an IR camera calibrated to display temperature values across an object or scene, and allows for non-contact measurements of an object’s temperature. 

  7. Augmented Reality Moves Closer To Reality With New Materials

    Augmented reality (AR) is likely to usher in the next generation of computing and will have a huge impact on our society over the next several decades. For the developers of AR glasses, field of view (FOV) is a key performance standard upon which lens material is evaluated.

  8. High-Speed Imaging In Biomedical Microfluidic Applications: Principles & Overview

    Microfluidics is a highly interdisciplinary field that employs state-of-the-art microfluidic chip technologies to guide fluid(s), and tiny objects within, through channels with micro-sized cross-sections. This paper provides a set of basic equations that can be used to approximate the fundamental physical principles involved in microfluidics, as well as a series of recent peer-reviewed publications that utilized high-speed cameras.

  9. Optimal Lighting Design Boosts Efficiency Of Medical Diagnostic Instruments

    For designers of medical diagnostic instruments, partnering with a reliable lighting expert can ensure the lighting system is optimized and generates homogeneous light that facilitates comparable and meaningful in vitro diagnostic analysis.

  10. Model Based Analysis: A New Way To Measure Thin Films

    Measuring the surface topology and thickness of thin films is important for characterizing many devices, but it can be difficult to resolve small enough features while covering a wide area. A new technique, model based analysis, creates a 3D map of both the film’s surface and thickness.
