摘要： The invention relates to an optical, integrated alignment device for accurately aligning and efficiently coupling energy between in-plane optical devices. A semiconductor substrate is etched to include a groove for an optical fiber and a lens for passing an optical signal from a cut fiber to a photodetector. The etched semiconductor substrate may be used to pass an optical signal from a surface light emitting device to a cut fiber. The end of the optical fiber is cut at a slant that redirects an optical signal from the fiber through the lens or vice-versa. The lens focuses the optical signal onto a target.

摘要： A system for the remote detection and analysis of trace chemical agents in the air. A beam of electromagnetic radiation is used to radiate a cloud. The radiation energy that is absorbed by the cloud is thermalized by collisional energy transfer between the molecules that absorb the radiation. Increases in the cloud temperature increase the emission intensity of the molecules against the background, resulting in improved detection of the target molecules. A tracking telescope is used to collect the thermal emissions generated by the radiation beam. A spectrometer is used to resolve the emissions from the cloud and generate an emissions spectrum. The wavelength of the electromagnetic radiation can be selected to be in resonance with the absorption lines of water or oxygen molecules in the cloud, or to be in resonance with absorption lines of known target molecules in the cloud to generate the heat.

摘要： A multispectral imaging system (1) and method utilize an optical processor (3) for simultaneously comparing an input wavelength spectrum observed in a single spatial pixel in a scene image from a multispectral imager (2) with a plurality of template wavelength spectra to find a correlation. The optical processor exploits the three-dimensional attributes of optical correlation to perform massively parallel correlation processing by modulating (4) respective ones of a plurality of spectral bands of the input wavelength spectrum of an incident light beam (6) with modulating elements (5) to alter at least one property of the incident light beam by a value corresponding to the observed intensity of the input spectrum in the respective spectral band. In a disclosed embodiment, the modulated beam is expanded and transited through a spatial light modulator (7) having a two-dimensional array of modulating elements. Each row of the elements of the array alter the at least one property of the incident light by values corresponding to a particular template wavelength spectrum of a plurality of template wavelength spectra of the modulator. The values corresponding to each template spectrum are the conjugates of the representative values of the modulating elements of the template spectrum of the plurality of template spectra.

摘要： An optical filter and detector, and a related method for its operation, in which signal photons are admitted into a detector cell and selectively excite atoms or molecules of a vapor to a selected metastable state. An illuminating laser then photoionizes a large proportion of the excited atoms or molecules, and the resulting free electrons are collected as a measure of the number of incident signal photons. The initial excitation step to a metastable state is highly sensitive to the wavelength of the signal photons and therefore acts as a narrowband filter.

摘要： Apparatus and a related method for generating a uniphase reference beam from a weak and aberrated input probe beam in an optical system. A portion of the input probe beam is split off and injected into the cavity of a laser, such as a semiconductor diode laser, where four-wave mixing takes place and an amplified input wave or its phase conjugate is output. Because the laser cavity is selected to provide single-mode operation, the laser provides not only amplification but an output that includes a uniphase wave, which may be interfered with the original aberrated input probe beam for purposes of obtaining wavefront information.

摘要： A wavelength controlled optical true time delay generator (14) utilizes passive switching to direct an optical beam to different length paths depending on the input wavelength. In one embodiment a dispersive element (20) is used to reflect the input beam at different angles depending on the incident wavelength. Different optical paths are then provided for the light reflected at different angles. In another embodiment, an optical fiber (50) is provided with reflective gratings (52), each of which are reflective at different wavelengths. The gratings (52) are positioned at different lengths along the optical fiber (50) to provide for different path lengths of light reflected by the gratings and back down the optical fiber (50) to an optical output (38). The true time delay generator (14) provides for a true time delay of any length in a low loss switching mechanism which is relatively inexpensive and compact.

摘要： A system for summing RF modulated optical signals. In order to compensate for performance degradation at the summing junction, the system utilizes four-wave mixing elements to provide the phase conjugates of each of the modulated RF signals. The phase conjugates of the RF modulated optical signals are summed at the summing junction. The use of the phase conjugates of the RF modulated optical signals compensates for optical phase errors known to degrade performance when summing RF modulated optical signals.
