The above objects are achieved with a compact neuro-otologic testing device and method of utilizing the same according to the present invention. The device according to the present invention provides an image producing laser with a right hand, servo controlled galvanometric based XY interface. The high quality closed loop servo control system that can drive the target (i.e. the laser image) in excess of 1,000,000 degrees/second2 and at velocities in excess of 12000 degrees/second. The bandwidth of the XY interface is greater than 400 Hz, providing high image reproducibility. The repeatability and position accuracy of the target is +−3 arc-seconds and the field of range of the XY interface are about 60 degrees (i.e. about 60 degrees horizontal and 60 degrees vertical).
