Patent number: 8279424Abstract: 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.Type: GrantFiled: February 10, 2010Date of Patent: October 2, 2012Assignee: The Boeing CompanyInventors: David C.

Patent number: 7860401Abstract: 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.Type: GrantFiled: December 13, 2007Date of Patent: December 28, 2010Assignee: The Boeing CompanyInventor: Jonathan M.

Patent number: 7667826Abstract: 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.Type: GrantFiled: February 29, 2008Date of Patent: February 23, 2010Assignee: The Boeing CompanyInventors: David C.

Patent number: 7615737Abstract: An angle absolute encoder comprises a code rod encoded with code marks configured in segments, such that each successive segment has an increasing number of code marks, arranged at an angle to the rotation axis depending on the number of code marks in each segment. The angle of the code mark is determined by the number of code marks in the respective segment, the width of the segment parallel to the rotation axis of the code rod and the radius of the code rod. The angular resolution increases according to the number of code marks in each segment. Light is reflected from or transmitted through the code marks and detected by a light detector to determine absolute angle position.Type: GrantFiled: May 8, 2007Date of Patent: November 10, 2009Assignee: The Boeing CompanyInventors: Jonathan M.

Patent number: 7230227Abstract: 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.
