Meridian® FLEX Camera Testing Platform (Patent Pending)The Meridian FLEX platform provides camera manufacturers and integrators with a powerful tool that’s flexible enough for the R&D lab and fast enough for production camera testing. At its heart is a high-speed high-precision robot that can place a target at any specified field point in a variety of different instrument configurations.

Meridian FLEX offers Cartesian and spherical polar coordinate systems for precise target pointing, and Meridian FieldPoint software handles the complex math, so coordinate transforms are performed seamlessly. The robot then points either the target projector at the Device Under Test (DUT), or points the DUT at the target projector. And finally, there are split configurations in which one motion axis is assigned to the DUT and the other to the target projector.

Selecting the appropriate configuration depends on the maximum field of view of the DUT, the DUT housing geometry, the size and proximity of adjacent support electronics, and convenience. An important advantage of mounting the DUT to the robot is that it may then be pointed at optional stimulus stations other than the target projector, thereby enabling the assessment of parameters such as veiling glare, signal transfer function, and chromatic characteristics.

The standard optical source for testing is a Meridian® Focusing Target Projector (FTP), which is used in the measurement of MTF and geometric imaging parameters such as distortion. Prior to testing, an easily interchangeable FTP of a focal length suitable for the DUT is mounted in the FLEX. Future product offerings will include target projectors for measuring LWIR cameras.

Meridian FLEX with FieldPoint software will measure multiple optical parameters of cameras, including:
     •  Horizontal and vertical resolution (MTF)
     •  Through-focus MTF (with FTP)
     •  Geometric Distortion
     •  Focal Length
     •  Field of View
     •  Bore-sighting and roll (with special DUT Nest)
     •  Stray light type measurements (with optional stimulus source)
     •  Chromatic Functions (with optional stimulus source)
     •  Signal Transfer Function (with calibrated stimulus source)
