An unsteady hand can ruin the most epic picture moment. The engineers at Google understand this and have taken steps to optimize the motion and image stabilization algorithms in their Pixel 2 camera. The Google Pixel 2 has been integrated with PI’s H-860 high speed hexapod system that accurately simulates motion with 6 degrees of freedom and results in pinpoint accurate crisp images.
Color perception is based on the wavelengths of light that are reflected from, absorbed by, or emitted by an object. Light can be reflected via specular or diffuse reflection depending on whether or not a surface is smooth (like mirrors), rough, or a mixture of both. When measuring reflection from an object, it is important to consider which type of reflection is dominant, and whether some or all the reflected light needs to be collected. This article discusses the best practices for making good reflected color measurements that can be used in a wide range of optical imaging applications.
Bio-imaging and detection techniques that use non-linear optical (NLO) phenomena have led to great advancements, such as super-resolution images, label-free visualization of naturally occurring biomolecules, and greater freedom for working with in-vivo samples. Many NLO systems rely on the high peak pulse intensity of femtosecond lasers for signal generation, and demand that optical filters and mirrors integrated into these systems have an appropriate laser damage rating, and the reflective components be controlled for both group delay dispersion (GDD) and flatness. This white paper discusses the importance of choosing thin-film optical components for NLO systems to ensure optimal signal strength, resolution, and image quality.
LIDAR is now being used for obstacle avoidance in autonomous vehicles, urban planning, security, infrastructure development, and many other growing applications.

MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® BeamWatch® AM, the industry's first non-contact laser beam monitoring system for additive manufacturing. BeamWatch AM is a lightweight, compact system designed for real-time measurement of focal shift during laser startup of powder bed fusion manufacturing processes. It measures key beam size, position, and quality parameters, including focus spot size and beam caustic. These measurements allow users to more easily determine when the beam is aligned and in focus, providing more consistent metallurgy. Measurements can be displayed as tabular, 2D, and 3D views, providing a quick and realistic display of laser characteristics.
