Polarization Cameras for Remote Applications

4D Technology Corp.Request Info
 
4D Technology's Polarization Cameras for Remote ApplicationsPolarCam™ snapshot micropolarizer cameras capture images of multiple polarized angles from each video frame, enabling a range of image enhancement techniques and polarimetric measurements. Small, fast and field-proven, these unique cameras suppress or boost data content without image blur, for applications in image enhancement, industrial monitoring, remote sensing, stress measurement and more.

Proprietary micropolarizer technology enables the PolarCam’s broad spectral response, wide angular bandwidth and high extinction ratio. The micropolarizer array is bonded directly to the sensor and includes no moving parts, providing a fully solid state, Division of Focal Plane (DoFP) configuration.

High-resolution PolarCam cameras are available with 0.29, 1.4, 1.8 and 3.8 mega-pixel sensors. The video rate of up to 259 full frames per second ensures fast capture of quickly changing scenes. The CMOS high speed PolarCam can provide up to 170 frames/second at its full 1248 x 1082 resolution. Using customizable regions of interest the CMOS cameras provide frame rates in the kilohertz range.

Optional PolarView software provides 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.

Choose from a variety of accessories, including workstation kits, mounts and lenses. Mobility accessories enable use in remote applications, including a long-life battery, mobile cart, telescoping tripod stand and 1" format Macro Lens.

4D Technology can also provide complete illumination and imaging solutions based on the PolarCam.

GLOSSARY
polarization
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
polarimetry
The measurement of the rotation of the plane of polarization of radiant energy, usually through the use of a polarimeter.
remote sensing
Technique that utilizes electromagnetic energy to detect and quantify information about an object that is not in contact with the sensing apparatus.
image enhancement
The digitization process by which an image is manipulated to increase the amount of information perceivable by the human eye.
