Patent ID: 7651224

Claim:
A Dynamic Visual Vestibular Acuity Testing protocol of for testing an observer's ability to resolve a critical detail in a visual target under conditions of relative movement, said protocol comprising the steps of providing passive oscillation movement to the patient during testing through a movement mechanism; and displaying a laser based visual optotype images in the form of a non-circular optotype as a visual target to the patient during testing from a testing device including a housing having a laser opening therein and mounted on the mechanism for providing passive movement to the patient, an image producing laser mounted within the housing adapted to project through the laser opening to form the visual target image for testing the observer's ability to resolve a critical detail in the visual target under conditions of relative movement, wherein the laser forming the image is controlled by a galvanometric based XY interface having a closed loop servo control system that can drive the image in excess of 1,000,000 degrees/second 2 and at velocities in excess of 12000 degrees/second.
