摘要： Shortwave infrared (SWIR) hyperspectral imaging (HSI) systems comprise a supercontinuum laser source configured to illuminate objects and a receiver comprising a spectrometer configured to receive light reflected from the objects. In some cases, hyperspectral images can be created by raster scanning of the source/receiver across a scene. The supercontinuum laser source provides active illumination to allow collection of hyperspectral imagery during day (including overcast conditions) and night.

摘要： Provided is a resonance converting apparatus. The resonance converting apparatus preferably includes a resonant circuit, a bridge-type converter, and a synchronous rectification circuit. In which the resonant circuit has a transformer. The bridge-type converter connects with a primary side of the transformer, and operates open or close according to a switching signal. The synchronous rectification circuit further includes a pair of rectification transistors and driving circuits. The driving circuits correspondingly connect with channels to the rectification transistors, and respectively examine the current passing through the rectification transistors. A sensing signal is then generated. In accordance with the switching signal and the sensing signal, a driving signal is generated for driving the rectification transistor. Consequently the apparatus can raise the efficiency of the resonance converting apparatus.

摘要： A heterodyne communication system uses coherent data modulation that is resistant to phase noise. In particular, a pilot tone and reference clock signal are transmitted along with the modulated data to form the basis of an electrical demodulation local oscillator at the receiver. The pilot tone and/or reference clock signal carry phase noise which is correlated with the phase noise in the data signal. At the receiver, the local oscillator is generated from the pilot tone and reference clock signal in a manner so that the local oscillator also has phase noise which is correlated with the phase noise in the data signal. Thus, the two noise components can be used to cancel each other during demodulation of the data signal using the local oscillator.

摘要： A transmitter subsystem generates an optical signal which contains multiple subbands of information. The subbands have different polarizations. For example, in one approach, two or more optical transmitters generate optical signals which have different polarizations. An optical combiner optically combines the optical signals into a composite optical signal for transmission across an optical fiber. In another approach, a single optical transmitter generates an optical signal with multiple subbands. The polarization of the subbands is varied, for example by using a birefringent crystal. In another aspect of the invention, each optical transmitter generates an optical signal containing both a lower optical sideband and an upper optical sideband (i.e., a double sideband optical signal). An optical filter selects the upper optical sideband of one optical signal and the lower optical sideband of another optical signal to produce a composite optical signal.
