Latest Patents

Sebesta's latest patents include an "Optical Inertial Reference Unit for Kilohertz Bandwidth Submicroradian Optical Pointing and Jitter Control." This device provides an inertially stabilized laser beam as an optical reference. It consists of a base and a small stabilized optical platform that emits the laser beam. The platform connects to the base through a mechanical flexure that allows relative motion in two axes. High-bandwidth angular rate sensors affixed to the platform measure platform motion in inertial space. Linear displacement sensors measure relative motion between the base and platform. A closed-loop control system accepts these sensor measurements and commands actuators that null the sensed platform motions, maintaining the optical platform fixed in inertial space. The digital controller implements a Sensor Blending Kalman Filter that blends high-frequency signals from the platform with low-frequency signals from a DC sensor (gyroscope) external to this device but affixed to the common base. The controller enables both stabilization of the laser beam and commanded pointing of the beam in inertial space.

Another significant patent is the "Optical Inertial Reference Generator," which is a system for stabilizing an optical line of sight. This optical system includes primary optics and relay optics, featuring a jitter rejection mirror located within the path of the relay optics. An auto-alignment system is provided for maintaining alignment of the jitter rejection mirror in response to a control signal. An auto-alignment sensor detects jitter in a reference beam passing through the jitter rejection mirror, and the generated control signal is used to reduce the jitter. The reference beam is supplied by a stabilized source of laser signals, which are received by the primary optics and relayed to the jitter rejection mirror.
