screws. For safety and optimum performance, you are strongly

recommended to use with Vicon MX only tripods and wall mounts that

Vicon Motion Systems has specified as suitable.

Camera Strobe Units

The strobe unit attached to the front of an MX Camera is configured

with LEDs (Light Emitting Diodes), which illuminate the capture

volume. The strobe unit generates a bright flash of light, which

illuminates the markers (coated with a highly retroreflective material)

attached to the subject, and which coincides with the time the

camera’s shutter (if present) is open. The reflected strobe light passes

through an optical filter with a spectral response such that only light

with the same characteristics as the strobe passes into the lens. The

lens collects the light and forms a focused image of the markers on

the camera’s sensor plane. The camera electronically converts the

pattern of light into data that represents the position and radius of

each marker in the image. For details on the filters supplied with each

strobe unit, see Camera Lens Filters on page 3-8.

The strobe unit for F-series and MX+ Cameras, shown in Figure 3-7,

uses surface-mount LEDs. These have a wide illumination angle and

are all aligned forwards, giving even illumination across the volume

without the need to manually optimize the LEDs. These strobe units

are available in Visible Red (VR) and Near Infrared (NIR) versions.
