PolarCam Snapshot Micropolarizer Cameras

PolarCam CCD Snapshot Micropolarizer Camera

PolarCam CMOS polarization based cameras

PolarCam™ 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 polarization cameras suppress or boost data content without image blur, for applications in image enhancement, polarimetry, birefringence measurement, 3D shape, remote sensing, defect detection, machine vision and autonomous vehicle vision.

Proprietary micropolarizer technology enables 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.

Micropolarizer technology enables PolarCam cameras to acquire four polarization angles simultaneously.

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 new CMOS high speed PolarCam can even 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.

PolarView Real-time Analysis Software

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. Dozens of included tools let you scale, sample, analyze and visualize the data, then save images and movies of each parameter. The Polarization Ellipse tool lets you determine and visualize the AoLP, Circularity and Linearity.

An optional high speed computer system maximizes performance.

The PolarCam Software Development Kit assists you in accessing information from PolarCam cameras for analysis and further manipulation. The SDK gives you access to common camera controls and settings. You can access and output the raw image frame and parsed polarization states, and calculate the polarization parameters including birefringence and retardance.

Accessories to Assist in your Application

PolarCam Macro LensExpand the capabilities of the PolarCam™ snapshot micropolarizer cameras with a range of accessories.

The 1" format Macro Lens offers manual zoom and iris control (F1.9 - close) and a focal length range from 16-100mm. This general purpose, C-Mount lens will work well with all PolarCam cameras except the H model.

This rugged, compact aluminum Tripod adjusts from fully folded (15.4") to 61.6" height. The tripod legs can be independently locked at different angles to shoot in cramped quarters, on uneven terrain or at low camera angles. The ball head offers separate head and pan locks and a 360° pan index. Includes carrying case.
