Abstract: According to one embodiment, a laser detection and ranging system includes a beam forming element that is optically coupled to a light source. The light source generates a light beam that is split by the beam forming element into multiple beamlets and directed toward a target. At least one of the beamlets are reflected from the target as backscattered light that is received by a detector that generates a signal indicative of a characteristic of the target.

Abstract: A spectral ellipsometer that enables complete simultaneous measurement of ellipsometric parameters of a surface with thin films and coatings for the full wavelength range of interest by using an imaging spectrograph together with a novel optical arrangement that disperses the polarization information of a time-invariant train of optical signals in a linear spatial array of points along or parallel to an input aperture or slit of the imaging spectrograph and disperses the polarization information in wavelength perpendicular to the aperture or slit to provide a two-dimensional spectrograph image that is collected and stored by an imaging array with one axis relating to wavelength and the other axis relating to the light polarization. Multiple simultaneous measurements of the spectral ellipsometric parameters .psi. (psi) and .DELTA. (delta) are taken at all wavelengths without the need of any time-varying or mechanically-moving optical elements. The ellipsometer can be used for real-time measurements of ellipsometric parameters of a moving or static surface with the thin films and coatings.

Abstract: According to one embodiment, a system for measuring vibration includes multiple spatially separated detectors coupled to a differential signal analyzer and a light source. The light source generates a coherent light beam onto a target that is reflected as backscattered light. The differential signal analyzer receives signals from each of the detectors indicative of backscattered light from the target. The differential signal analyzer then applies a phase shift to a subset of the received signals and combines the phase shifted signals with signals from other detectors to form a differential signal representative of physical vibration of the target.

Abstract: An efficient system (10) for measuring target characteristics via a torsion mode beam of electromagnetic energy. The system (10) includes a first mechanism (34, 38, 40, 42, 16) for transmitting the torsion mode beam toward a target (12). A second mechanism (16, 18, 20) receives the resulting target return beam and provides a first signal in response thereto. A third mechanism (26, 28) employs the first signal to determine rotational characteristics of the target (12). In a specific embodiment, the system (10) further includes a fourth mechanism (20, 26) that reduces or eliminates noise in the return beam based on common mode noise rejection. A fifth mechanism (32) identifies the type of the target based on the target rotational characteristics via comparison to predetermined target rotational signatures (36). An additional mechanism (24, 40, 42) selectively switches the mode of the beam between a first mode and a second mode. The first mechanism (34, 38, 40, 42, 16) and second mechanisms (16, 18, 20) employ a laser transceiver (16) having a transmit chain (34, 38, 40, 42, 16) and a receive chain (16, 18, 20). The transmit chain includes a time-division multiplexer (34) or a spatial multiplexer (34, 62) for selectively transmitting the beam of electromagnetic energy or for selectively transmitting first and second spatially separated beams characterized by the first and second modes, respectively. The receive chain (16, 18, 20) includes a corresponding time-division demultiplexer (20, 26) or spatial demultiplexer (16, 64, 66, 26), respectively, for providing the first signal. In a more specific embodiment, the first mode is a left-handed Laguerre-Gaussian torsion mode, and the second mode is a right-handed Laguerre-Gaussian torsion mode. The third mechanism (26, 28) determines rotational Doppler due to reflection of the beam of electromagnetic energy from the target.
