    Abstract: A laser-based altimeter for use on-board an aircraft comprises: a first housing including a hollow cavity and an exit aperture, and a second housing including a hollow cavity and an entrance aperture. A laser source and a plurality of first optical elements are fixedly supported in a compact configuration within the hollow cavity of the first housing. The plurality of first optical elements directs laser beams generated by the laser source from a first optical path to a second optical path which exits the first housing through the exit aperture. At least one second optical element is configured within the hollow cavity of the second housing to form a telescope with a predetermined field of view. The telescope receives at the entrance aperture reflections of the pulsed laser beams from objects within the field of view thereof and focuses the received reflections substantially to a focal point. A light detector is included for receiving and converting the focused reflections into electrical signals representative thereof. The first and second housings are fixedly secured in alignment with respect to each other to permit the second optical path of the pulsed laser beams to be adjusted within the field of view of the telescope. A mirror apparatus is the only first optical element of the plurality that is fixedly adjustable for directing the second optical path within the field of view of the telescope, the mirror apparatus being lockable in place after final adjustment. The first and second housings may be part of a common housing.

    Abstract: A method for determining a range to a target comprises rotating a mirror unit around a scan axis. A light pulse is reflected off of a transmitting portion of the mirror unit toward the target. A light pulse, received from the target, is reflected off of a receiving portion of the mirror unit toward a receiver. The method includes compensating for a lag angle, caused by the rotation of the mirror unit around the axis, between the time the light pulse is reflected from the transmitting portion and the time the received light pulse is reflected from the receiving portion. The compensation includes angularly offsetting the transmitting portion about the scan axis from a surface plane of the receiving portion.

    Abstract: A light detection and ranging system includes a transmitter transmitting a transmitted light pulse timing sequence, with pseudo-random timing and including a plurality of light pulses, toward a target. An optical receiver receives a reflected light pulse timing sequence including a plurality of light pulses from the target. An electronic control unit identifies a time delay between the transmitted light pulse timing sequence and the reflected light pulse timing sequence as a function of a correlation between the transmitted and reflected light pulse timing sequences.

    Abstract: Disclosed is a fuel injector (110) for a gas turbine engine combustor that includes a fuel nozzle (126) for injecting fuel into the gas turbine engine combustor and a fiber optic microphone (140) operatively associated with the fuel nozzle for measuring acoustic pressure differentials within a combustion chamber (14) of the gas turbine engine combustor. The fiber optic microphone includes a fiber bundle having at least one light transmitting fiber and one light receiving fiber; and a dynamic pressure-sensing diaphragm operatively spaced apart from a sensing end of the fiber bundle. The diaphragm has a reflective surface and is formed from a material capable of withstanding temperatures associated with flame exposure. The diaphragm is adapted and configured for deflecting in response to acoustic pressure changes within the combustion chamber. The fuel injector can further include a mechanism for measuring the temperature of the diaphragm, so as to account for changes in the material properties of the diaphragm caused by temperature changes in the combustion chamber.
