    Abstract: An interferometer is provided, comprising a source, a unit under test (UUT) with at least a first surface and second surface, a reflective optic, a detector and light from the source. The light is transmitted through the unit under test and reflects off of the reflective optic, which directs the light back to the unit under test. A first portion of light is reflected off the first surface of the UUT. A second portion of light is reflected off the second surface of the UUT. The first and second portions of light are then reflected by the reflective optic and are then transmitted through the UUT. The two portions of light are incident on the detector, where the first and second portions of light coherently add and the interference pattern is detected by the detector. A method for measuring the transmitted wavefront of the UUT is also provided.

    Abstract: A Fizeau or other interferometer is used to provide high resolution, in-situ calibration of an external angle measurement system such as widely spaced high stability plane mirror interferometers (HSPMIs)). The calibrated measurement system then measures mechanical tilt during shearing. The tilt data is used to correct the sheared data, preferably before computation of the rotationally invariant (RI) terms. Altematively, the data may be used to compute the spurious quadratic term and correct after integration.

    Abstract: In a power driven roller conveyor having a plurality of rollers each connected to a shaft and a plurality of driven sprockets one of which is rotatably mounted on each of the shafts, a torque-responsive coupling is interposed between a driving member connected to each sprocket and a driven member connected to each shaft so that the rotation of any roller will be interrupted if the resistance to rotation exceeds a desired value, thereby permitting articles on the conveyor to be stopped and accumulated without undue scuffing and wear on the articles or on the rollers. The coupling consists of a wobble plate which is connected to the driven member for oscillating movement about a center coincident with the axis of the shaft and which has a surface disposed transversely to the axis of the shaft and facing the driving member. The wobble plate is spring urged toward the driving member. A driving ball, rotatably mounted in a socket in the driving member engages and displaces the surface of the wobble plate to an oblique relation with the axis of the shaft, thus forming, a coupling which will transmit motion until the resistance thereto is sufficient to overcome the spring bias on the wobble plate. The ball then rolls on the surface of the wobble plate which oscillates.

    Abstract: A Fizeau interferometer is provided with an adaptive null optic whose shape may be selectively varied in a controllable way by the selective application of external mechanical loads to enable the interferometer to be dynamically adapted to testing a variety of aspherical segments of differing shapes without the need for providing individual reference surfaces to match the various shapes of each test segment.
