    Abstract: An optical transceiver is provided with a light pipe that intercepts, offsets and redirects a portion of the collimated transmit beam to create a virtual object in the receiver field-of-view to perform the BIT. The light pipe comprises an input face and first reflective surface in the transmitter FOV to intercept a portion of the beam along a first axis and re-direct the beam, a second reflective surface and output face in the receiver FOV that re-directs the portion of the beam along a second axis 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: A polarimeter and method of polarizing incoming light includes an optical assembly, a first adjustable circular retarder that rotates the polarization content of incoming light, a polarization beam splitter that receives light from the adjustable circular retarder and polarizing the light into a first portion of light having a first polarization and a second portion of light having a second polarization. The first portion of light is directed to a focal plane and the second portion of light is directed to the optical assembly. The optical assembly is switchable between a polarizing mode of operation in which the first portion of light is viewable at the focal plane in absence of the second portion of light and an imaging mode of operation in which the first portion of light and the second portion of light are viewable at the focal plane.

    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.

    Abstract: A receiver including an analyzer and a detector coupled to the output of the analyzer. The analyzer selects a polarized component of a return beam for input to the detector. The analyzer may be linear, circular or elliptical. Coupled with a laser adapted to output a polarized beam, the receiver provides an active optical ‘target detector. An arrangement may be included for compensating for rotation and ellipticity in the returned beam. In one embodiment, the arrangement for compensating for rotation of the orientation of linear polarization in the returned beam includes a Faraday rotator positioned between the transmitter and the analyzer. An arrangement is disclosed for varying the rotation in the returned beam using a Faraday rotator until a maximum transmittance is achieved. In an alternative embodiment, the arrangement for compensating for ellipticity in the returned beam includes an electro-optical modulator positioned between the transmitter and the analyzer. In another alternative embodiment, two electro-optical modulators are included to compensate for any change in the polarization state in the returned beam.

    Abstract: A laser pump cavity assembly having a laser rod with a ground outer surface positioned concentrically within an annular jet sleeve which is, in turn, positioned concentrically within an annular outer sleeve. The outer sleeve is coated with a dielectric coating having slits therein arranged to receive focused optical pump radiation from respective laser diode arrays, the pump radiation being transmitted through the outer sleeve and jet sleeve to excite the laser rod. The jet sleeve is positioned to define cooling fluid chambers between the outer sleeve and the jet sleeve, and between the jet sleeve and the laser rod, and is provided with a series of jet holes for directing cooling fluid to impinge perpendicularly on the laser rod. The end faces of the jet sleeve and outer sleeve are further coated with dielectric material to enhance the efficiency of the device. The cooperating end caps which mount the outer sleeve, jet sleeve, and laser rod employ a number of advantageous self-aligning and sealing features.
