摘要： A circuit for detecting leading or lagging phase relationship between first and second two-level input signals at each level transition of a selected one of the input signals and comprising first and second Exclusive OR gates each having first and second input terminals and a single output terminal and each responsive to signals of equal and non-equal logic levels supplied to the first and second input terminals thereof to produce an output signal having high and low logic levels, respectively. Further connections supply the first and second input signals to the first input terminal of the first and second Exclusive OR gates, respectively. Also provided is a decoder responsive to the output signals of the first and second Exclusive OR gates to determine the phase relationship of the first and second signals at each level transition of the selected input signal and for generating and supplying to the input terminals of the first and second Exclusive OR gates, after each determination of phase relationship, an acknowledgment signal which prepares the circuit for the reception of the next transition of the selected input signal.

摘要： An ephemeris refinement system includes satellites with imaging devices in earth orbit to make observations of space-based objects (“target objects”) and a ground-based controller that controls the scheduling of the satellites to make the observations of the target objects and refines orbital models of the target objects. The ground-based controller determines when the target objects of interest will be near enough to a satellite for that satellite to collect an image of the target object based on an initial orbital model for the target objects. The ground-based controller directs the schedules to be uploaded to the satellites, and the satellites make observations as scheduled and download the observations to the ground-based controller. The ground-based controller then refines the initial orbital models of the target objects based on the locations of the target objects that are derived from the observations.

摘要： A constant volume gas cell optical phase-shifter, particularly applicable for phase-shifting interferometry, contains a sealed volume of atmospheric gas at a pressure somewhat different than atmospheric. An optical window is present at each end of the cell, and as the length of the cell is changed, the optical path length of a laser beam traversing the cell changes. The cell comprises movable coaxial tubes with seals and a volume equalizing opening. Because the cell is constant volume, the pressure, temperature, and density of the contained gas do not change as the cell changes length. This produces an exactly linear relationship between the change in the length of the gas cell and the change in optical phase of the laser beam traversing it. Because the refractive index difference between the gas inside and the atmosphere outside is very much the same, a large motion must be made to change the optical phase by the small fraction of a wavelength that is required by phase-shifting interferometry for its phase step. This motion can be made to great fractional accuracy.
