Abstract: A total air temperature sensor includes a probe secured to a first side of a vehicle surface. The probe includes an air inlet and a temperature sensing element. Air flows into the air inlet and passes by the temperature sensing element. The temperature sensing element produces a temperature sensing element electrical signal as a function of a temperature of the air. The total air temperature sensor also includes an electronics package secured to a second side of the vehicle surface. Electronics in the electronics package receive the temperature sensing element electrical signal from the temperature sensing element and determine a total air temperature as a function of the temperature sensing element electrical signal.

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.
