The Imatest Motorized Gimbal allows for automated rotational positioning of your camera. The Motorized Gimbal includes two axes of automated rotational positioning and one axis of manual rotational positioning. The Motorized Gimbal is designed to be used for precision camera-to-target alignment and/or for executing automated test plans that include multiple camera poses.

The Motorized Gimbal is available in two configurations:

  • Standard configuration (motorized pitch & yaw)
  • Stray light (flare) test configuration (motorized roll & yaw)


The Imatest Motorized Gimbal consists of two Zaber X-RSW rotational stages and an Edmund Optics Goniometer. It can be mounted to the Imatest Modular Test Stand, Motorized Test Stand, standard tripods, or metric optical breadboards.

The Motorized Gimbal can be used for camera-to-target alignment and/or for general rotational positioning of a camera device. For example, the gimbal can be used for accurate camera-to-chart alignment and for positioning a test target at multiple locations in the image field, such as an SFRreg target from a target projector. 

The Motorized Gimbal comes in two configurations where the key difference is the style of the plate that the camera is mounted to (and the way the camera is meant to be mounted):

  • Standard configuration: Comes with a standard camera mounting plate. Meant for motorized control of pitch and yaw, plus manual control of roll (via goniometer). 
  • Stray light (flare) test configuration: Comes with a shortened camera mounting plate. Meant for motorized control of roll and yaw, plus manual control of pitch (via goniometer)

The standard configuration is more generally useful, while the stray light test configuration is meant for stray light (flare) testing. The stray light test configuration has a shortened camera mounting plate which allows a user to place the front of the camera at the gimbal’s center-of-rotation without the risk of blocking any light from a light source pointed at the camera. This configuration provides control over the azimuth angle (via camera roll) and field angle (via camera yaw) of the light source with respect to the position of the camera. Users can perform stray light testing with the standard configuration as well, but may encounter scenarios where parts of the gimbal or mounting plate block light from the light source, impacting the test. 


  • Easily connect using USB 2.0 or serial communication ports and send commands over RS-232
  •  Zaber’s Console software makes it easy to control the speed and position of the target, change the device settings, and write custom scripts.
  • The rotational stages include indexed knobs which provide manual control even without a computer.
  • Rotational Travel (standard configuration): Pitch = 360º, Yaw = 360º, Roll = ±10º
  • Rotational Travel (stray light test configuration): Pitch = ±10º, Yaw = 360º, Roll = 360º
  • Maximum Speed: 450º/s
  • Control Interface: USB Serial Interface, Zaber Console Control Software, Python 3 – Zaber Motion Library, C++ Zaber Motion Library
