摘要： A dual mode rotary joint as described herein can be utilized in an electromagnetic communication system such as a radar system. The dual mode rotary joint can be used to rotatably couple an antenna architecture to its mounting structure. One embodiment of the dual mode joint includes a waveguide configured to propagate radio frequency (RF) signals, and endcaps coupled to the ends of the waveguide. Each endcap is reflective for RF signals and transmissive for optical signals.

摘要： A Doppler velocimeter apparatus that may have a coherent light source for generating a beam of coherent light. A modulating subsystem may receive and modulate at least a first portion of the beam of coherent light to form a first beam portion, the first beam portion forming a frequency offset and being a modulated, coherent optical signal. An optical element may receive the first beam portion and direct the first beam portion at a subject, the first beam portion being reflected from the subject to form a reflected beam that has a frequency that is modified in relation to the motion of the subject. A processing subsystem may receive a second portion of the beam of coherent light, and also the reflected beam, and uses the second beam portion and the reflected beam to determine a Doppler shift of the reflected beam.

摘要： A Doppler velocimeter apparatus and method of forming same. In one implementation a coherent light source is used for generating a beam of coherent light. An optical fiber receives the beam of coherent light. The optical fiber has an output face that is generally flat, thus enabling a first portion of the beam of coherent light to be reflected back on the optical fiber and to form a frequency offset, while a second portion of the beam of coherent light exits the optical fiber. A mechanism is used to move the output face of the optical fiber in an oscillating fashion so that the first portion of coherent light reflected back on the optical fiber produces an oscillating waveform that forms a frequency offset. An optical element receives the second portion of light from the face of the optical fiber and transmits it to a subject, and then receives a reflected optical signal back from the subject. The reflected optical signal, when mixed with the oscillating frequency offset, produces a Doppler shift that is dependent on the motion of the subject. A processing subsystem processes the mixed signal and determines the Doppler shift of the reflected signal.

摘要： A method for point-to-point communication over an optical channel is provided. An optical beam is received at a first corner cube modulated retro-reflector. Simultaneously, the optical beam is received at a second corner cube modulated retro-reflector. The first and second corner cube modulated retro-reflectors are adjacent to each other, are co-boresighted, and have an aggregate diameter that is smaller than the far-field Instantaneous Field of View of a receiver. The optical beam is modified by the first corner cube modulated retro-reflector by adding a first modulation to the optical beam, forming a first modulated optical beam. Simultaneously, the optical beam is modified by the second corner cube modulated retro- reflector by adding a second modulation to the optical beam, forming a second modulated optical beam. The first modulated optical beam and the second modulated optical beam combine to form a modified optical wavefront, which is reflected to a sender.

摘要： An assembly is provided that may be used in high data rate optical communications, such as free-space communication systems. The assembly may include a main optical receiver element and a lenslet array or other optical element disposed near the focal plane that collects an optical signal and focuses that signal as a series of optical signal portions onto a photodetector array, formed of a series of InGaAs photodiodes, for example. The electrical signals from the photodetectors may be amplified using high bandwidth transimpedance amplifiers connected to a summing amplifier or circuit that produces a summed electrical signal. Alternatively, the electrical signals may be summed initially and then amplified via a transimpedance amplifier. The assembly may be used in remote optical communication systems, including free-space laser communication environments, to convert optical signals up to or above 1 Gbit/s or higher data rates into electrical signals at 1 Gbit/s or higher data rates.
