Abstract: An ice detection warning system (10) mountable on board an aircraft for inflight monitoring of the airspace ahead of the aircraft comprises: a first plurality of optical elements (18) configured to direct a pulsed laser beam at a first wavelength from a laser source (14) into the airspace ahead of the aircraft; a second plurality of optical elements (32) configured to separate received backscattering of light from the laser beam into a plurality of predetermined wavelengths; a plurality of light detectors (50,52) for detecting the light of the separated plurality of wavelengths, respectively, and generating respectively corresponding plurality of electrical signals representative of the light detected thereby; and a processor (80) for processing the plurality of electrical signals to determine if airspace conditions ahead of the aircraft are likely to cause ice accretion on the surface of the aircraft, and for generating a warning indicative thereof. In one embodiment, the warning system includes an optical scanner (100) operative to scan the pulsed laser beam into the airspace ahead of the aircraft with a predetermined scan pattern, the scanner also being operative to receive the backscattering of light from the pulsed laser beam and direct it to the second plurality of optical elements which is configured to separate the received backscattering of light into the plurality of predetermined wavelengths.

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 wide field scanning laser obstacle awareness system (LOAS) for use on-board an aircraft is provided. The LOAS serves for alerting an operator of obstacles posing a risk of collision with said aircraft. The system comprising: a light source for generating a pulsed laser beam of light; a light detector; a plurality of optical elements for directing said pulsed laser beam from said system with a predetermined pattern scanned azimuthally over a wide field, said plurality of optical elements also for receiving reflections of said pulsed laser beam from at least one object along said predetermined pattern and directing said laser beam reflections to said light detector. The predetermined pattern includes a variation in elevation of the directed pulsed laster beam in relation to an elevation of the aircraft. Additionally, the system has means for determining substantially the azimuth position of the directed pulsed laser beam, means for determining substantially the elevation of the directed pulsed laser beam, and a display apparatus including an image screen for displaying a limited field of view, wherein the wide field of view of the system extends substantially beyond the field of view of the image screen. A processor means is coupled to said light detector, display apparatus, azimuth position determining means and elevation determining means for determining the location of the at least one object in range, azimuth and elevation in relation to a flight path of the aircraft. The processor means drives the display apparatus to display an indication representing the at least one object in range, azimuth and elevation. The indication of the at least one object comprises an image of a bar. The bar image is disposed vertically at the far left of the screen of the display apparatus when the object location is azimuthally outside the field of view of the display apparatus to the left, and the bar image is disposed vertically at the far right of the screen of the display apparatus when the object location is azimuthally outside the field of view of the display apparatus to the right.
