  1. Specifying Surface Figure And Wavefront Distortion For Multi-layer Optical Filters
    1/15/2019

    Optical filters are used in many applications and the surface figure and wavefront distortion requirements of filters are dependent on where and how they are used. If filters are only used in sensing applications with very tolerant detector geometries, there may be no need, in practice, to put any constraints on the surface figure or wavefront distortion. This white paper helps the reader understand where, when, how, and how much to specify wavefront distortion to ensure that functional requirements of filters are guaranteed while unnecessary and costly constraints are avoided.

  2. Making Waves: Nanosecond Pulsed Drivers For Flash LiDAR
    1/7/2019

    Rather than radio waves, most LiDAR systems use infrared lasers, particularly diode lasers. The limiting factor on a diode laser’s pulse features is not the laser itself — it is the electrical driver that supplies the electrons to the laser diode. This paper discusses challenges involved in optimizing nanosecond electrical driver performance in a flash LiDAR system.

    12/11/2018

    Deep learning is set to alter the machine vision landscape, enabling new applications and disrupting established markets. It’s never been easier to get started, but where do you begin? This article provides an easy-to-follow guide to building a deep learning inference system for less than $1000.

  5. Introduction To Sony Pregius® Global Shutter CMOS: High-Speed CMOS Sensor With Distortion-Free Global Shutter Technology
    12/11/2018

    Sony's Pregius global shutter CMOS technology truly fulfills its promise: crisp, clear, distortion-free images at high speeds. With Pregius, Sony does more than provide a migration path from their most popular CCD sensors. Pregius offers significant performance gains, and with its newly-announced third generation, additional on-sensor features.

  6. Imaging Reflective Surfaces: Getting Started with On-sensor Polarization
    12/11/2018

    Many vision systems struggle to overcome the effects of reflections and glare on reflective surfaces like glass, plastic and metal. Sony’s newest sensor technology can solve this problem with its pixel-level polarizer structure. This technology enables Sony polarized sensors to detect both the amount and angle of polarized light across a scene.
