    Abstract: Optical position encoding mechanisms and methods for use in reimaged optical imaging systems. In one example, a reimaged optical imaging system includes an imaging detector, an optical component, and at least one light source coupled to the optical component and configured to be reimaged onto the imaging detector, wherein a position of an image of the at least one light source at the imaging detector encodes a position of the optical component relative to the imaging detector.

    Abstract: An optical transceiver is provided with a light pipe (50) that intercepts, offsets and redirects a portion of the collimated transmit beam to create a virtual object in the receiver field- of -view (22 ) to perform the BIT. The light pipe comprises an input face and first reflective surface in the transmitter FOV (20) to intercept a portion of the beam along a first axis (38) and re-direct the beam, a second reflective surface and output face in the receiver FOV (22) that re-directs the portion of the beam along a second axis (30) towards the receiver to create the virtual object in the receiver FOV and an optical channel that guides the redirected portion of the beam from the first reflective surface to the second reflective surface to offset the second axis from the first axis. The same detector used during normal operation of the transceiver is used to perform the BIT, which may include a simple "on/off test or a radiometry test. The light pipe may be designed with an acceptance FOV that preserves collimation, which facilitates a measurement of alignment error between the transmit beam and receiver.

    Abstract: An optical imaging system and method including a movable pixelated filter array, a shutter mechanism to which the pixelated filter array is attached, and a controller configured to implement a data reduction algorithm. The shutter mechanism is configured to move the pixelated filter array into and out of the optical path, and the data reduction algorithm allows the controller to account for axial and/or lateral misalignment of the filter array relative to the imaging detector array or its conjugate. In certain examples, the controller is further configured to use the data reduction algorithms also to perform wavefront sensing, for example to estimate wavefront error.
