Polarized (IMX250MZR) machine vision area scan camera
The GO-5100MP-USB is a compact industrial polarization area scan camera built around Sony’s IMX250MZR polarized CMOS sensor. It features 5.1 MP resolution, a frame rate of 74 fps and an innovative 4-way polarizing wire-grid design creating a range of new imaging possibilities in industrial machine vision, traffic imaging and surveillance.
Each image pixel incorporates one of four separate polarizing nano wire grids angled at 0°, 45°, 90°, and 135° arranged in a regular pattern across the sensor. Thus, each block of four pixels can be used as a calculation block to determine the angle and intensity of light in a scene.
Advanced in-camera processing features
In-camera processing algorithms calculate polarization angle, light ratio, and appearance with diffuse light removed. Other functions display diffuse light only (without polarization) and average light for each pixel, plus pseudo-color overlays on monochrome or gray-tone images.
USB3 Vision interface
The GO-5100MP-USB is equipped with a USB3 Vision interface enabling it to provide full 5.1 megapixel resolution (in 8-bit output) at up to 74 frames per second. 10-bit and 12-bit output is also supported.
Here are a few applications where the Go Series industrial polarization cameras are especially suitable
The Go Series polarization cameras are the ideal industrial area scan cameras for a wide range of applications in machine vision, traffic and surveillance.
Material stress and strain in glass and plastics
Internal material stress “frozen-in” during manufacturing of glass and plastics can be problematic. Inspection systems for bottles, eyewear, window glass, etc. can benefit from GO-5100MP-USB polarization camera.
Surface scratches in glass and plastic products
Scratches, dents and inclusions in finished glass are often easier to detect by analyzing polarized light. Inspection systems for window glass, bottles, eyewear, and lenses can benefit from the GO-5100MP-USB camera.
The GO-5100MP-USB can be used in vision systems inspecting blister packages, vials, ampoules and other pharmaceutical items with shiny surfaces to identify damaged/incomplete packaging or foreign objects.
The GO-5100MP-USB can eliminate unwanted glare and reflections from car windshields making it possible to better see inside the cabin for better facial recognition and to provide better evidence in the case of seatbelt or mobile phone use violations.
Food and beverage inspection
The food and beverage industries are very sensitive to foreign objects in the finished food packages or drink bottles. Polarized imaging with the GO-5100MP-USB can be a new method for food inspection systems to better detect foreign objects.
Some of the challenges in imaging in outdoor surveillance situations are changing light conditions and disturbing reflections and glare. Surveillance applications can benefit from the polarized area scan camera’s ability to remove unwanted reflections improving image analysis and object detection.
Material science and manufacturing
An inspection system with a polarization camera such as the GO-5100MP-USB can be used to detect geometrical orientation of construction materials such as fiber composites. This can be useful in the research of new materials or in quality inspection in manufacturing processes.
Automotive paint spray inspection
Polarized imaging can be used to inspect the quality of spray painted surfaces in e.g., the automotive and furniture industry, looking for unwanted scratches, dust spots or uneven paint layers.
