Sensing and Imaging Applications


Polarimetry

Polarimetry

PolarCam cameras, with PolarView software, provide real-time display and calculation of key polarization parameters, including Degree of Linear Polarization (DoLP), Angle of Linear Polarization (AoLP), linear Stokes parameters (S0, S1 and S2) and more. Use the many included tools to process and analyze the data, then save images and movies of each parameter for comprehensive analysis.

Birefringence Measurement

birefringence, measure stress

4D snapshot micropolarizer cameras measure birefringence in glass and plastic, in real time, even on moving and rotating targets. These innovative cameras provide repeatable measurement of birefringence, letting manufacturers spot stress in bottles, flat panel substrates and optics.

3D Shape

3D reconstruction

PolarCam cameras and PolarView software calculate the linear Stokes polarization parameters to map the Angle of Linear Polarization of a 3D scene. The differing polarization angles of light from a surface can be used to determine the surface normals and reconstruct 3D scenes with a high degree of accuracy.

Remote Sensing

remote sensing

By capturing key polarization parameters including the linear Stokes parameters, 4D PolarCam cameras highlight information in remote sensing data for applications ranging from oceanography to astronomy.

Defect Detection

Defect Detection

Snapshot micropolarizer array technology enables PolarCam cameras to detect and measure defects in production environments. High speed imaging allows PolarCams to spot defects on moving and rotating objects, capturing problems that other cameras simply miss.

The 4D InSpec Surface Gauge is the first instrument for handheld, high resolution measurement of surface defects on precision surfaces.

Machine Vision

Machine Vision

4D PolarCam snapshot micropolarizer cameras detect and quantify differences in polarization to spot defects in materials, identify missing or excess material, reduce glare from highly specular parts, or to aid in pick and place operations.

Autonomous Vehicle Vision

Autonomous Vehicle Vision

4D PolarCam snapshot micropolarizer cameras detect and quantify differences in polarization, enabling glare reduction to provide discrimination between false reflected images and real images that other technologies cannot provide.
