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 block arrangement of optical elements is provided for use as a transmitter/receiver for a light detection and ranging (LIDAR) system. The block arrangement comprises: a plurality of glass modules aligned together as a block to form a plurality of optical paths therein and secured together to maintain said alignment; a collimated light source secured to said block for generating a coherent beam of light over at least one optical path in said block which guides said coherent beam of light to an exit point of said block; and a light detector secured to said block. The block serves for receiving a return coherent beam of light and is configured to conduct said return coherent beam of light to the light detector over at least one other optical path formed in said block.

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.
