    Innovative Design Process Fastracks UAV Laser Comms Development

    Using photonics technologies to establish communications in air-to-ground, air-to-air, and air-to-space fields offers many advantages related to transmission speed, low Size Weight and Power (SWaP) systems, spectrum regulations, and immunity to electromagnetic interference. Specifically in UAV laser communications, photonics technology has the potential to establish secure and reliable high-speed links that are also immune to jamming/spoofing, where transmissions cannot be detected, in contrast to traditional RF technology. This article discusses the additional advantages of using photonics in the design process of UAV laser comms development, and provides an example of a UAV laser transmitter under testing at Gooch & Housego.

  • The Evolution Of Ultrafast, Ultra-Precise Beam Steering Techniques For Micro-Material Processing

    When designing micromaterial processing equipment, manufacturers need to consider a complex interplay of numerous factors, such as extremely accurate positioning of lasers for cutting, drilling, scribing, or for marking at the highest rate possible.  In many integrated circuits, the required beam accuracies can be staggering. For example, processing equipment must be able to drill microvias and scribe trenches less than 10 μm in size. Display manufacturers must also accurately place and repair pixel circuitry at ever shrinking resolutions on increasing larger substrates. This requires advance tooling to avoid significant increases in processing time and costs.

  • The Fundamentals Of AOTF-Based Spectral Imaging And Polarimetry
    The Fundamentals Of AOTF-Based Spectral Imaging And Polarimetry

    Many hyperspectral imaging (HSi) systems use a diffraction grating to split up a line of an image into strips with different wavelengths and so build up a 3D image cube. While this push-broom process works well for capturing hyperspectral images where there is a built-in, one-dimensional relative movement between the camera and the object, there are many situations where band sequential imagers are more effective. This article explores the basics of acousto-optic tunable filter (AOTF) and polarimetric technology and discusses the advantages of using those approaches for hyperspectral imaging. By Alexandre Y.
