Abstract: Methods and apparatus for measuring thickness and related properties of transparent objects, such as glass. In one example a measurement system includes a light source that produces a collimated optical beam, a modulator that modulates the collimated optical beam to produce a collimated modulated optical beam, optics configured to direct the collimated modulated optical beam to illuminate the transparent test object, and a detector sub-system that receives an intensity-modulated optical beam output from the test object and measures variations in intensity of the intensity-modulated optical beam corresponding to an intensity modulation of the intensity-modulated optical beam, the intensity-modulated optical beam being derived from interaction of the collimated modulated input optical beam with the transparent test object, the detector sub-system being further configured to produce a representation of the thickness and/or related properties of the test object based on the measured variations in intensity of the intensity-modulated optical beam.

Abstract: Aspects are generally directed to optical receivers and methods for detecting a non-persistent communication superimposed on an overt communication channel. In one example, an optical receiver includes an optical resonator to receive an optical signal having one or more symbols encoded thereon at a modulated symbol repetition rate, the modulated symbol repetition rate being modulated relative to a nominal symbol repetition rate. The optical resonator is configured to emit an intensity-modulated output optical signal that has a variation in an intensity thereof corresponding to a symbol transition in the optical signal. The optical receiver further includes signal processing circuitry including a clock configured to generate a reference signal, a photodetector configured to generate a trigger signal, and a non-persistent communication decoder configured to determine a temporal misalignment between the symbol transition and the nominal symbol repetition rate based on the reference signal and the trigger signal.

Abstract: Optical signal receivers and methods are provided that include an optical resonator that allows an optical signal to enter and optical signal energy to accumulate at regions inside the optical resonator. A portion of optical signal energy is emitted from among various regions of the optical resonator, such that a combination of the emitted optical signal energy is disturbed when a phase transition occurs in the received optical signal. A detector aligned with the output detects the combined emitted optical signal energy and is configured to detect the disturbance and determine a characteristic of the phase transition in the received optical signal based upon the disturbance.

Abstract: Methods and apparatus for producing multi-spectral images having variable (non-uniform) magnification over the lateral extent of the image. In one example, a multi-spectral imaging system includes a first sensor sub-system configured to receive electromagnetic radiation in a first spectral band from a scene and to provide a first image signal, a second sensor sub-system configured to receive electromagnetic radiation in a second spectral band from the scene and to provide a second image signal, a processor coupled to the first and second sensor sub-systems and configured to produce a first image of the scene from the first image signal, and a second image of the scene from the second image signal, the second image having a variable lateral magnification, and a display coupled to the processor and configured to display the second image overlaid with the first image.
