Abstract: An apparatus for detecting icing conditions on an aircraft. The apparatus including a laser system configured and operative to generate a light signal and direct the light signal into a cloud and a lens component configured and operative to collect echo signals from a cloud caused by the light signal directed into the cloud by the laser system. The apparatus further includes a beam splitter component configured and operative to redirect signals received and passing through the lens component into at least first and second paths. Further provided is a supercooled large droplet (SLD) detector positioned to receive the redirected signals from the beam splitter. The SLD includes a first signal detector component configured and operative to perform a first color measurement on the first redirected signal; and a second signal detector component configured and operative to perform a second color measurement on the second redirected signal wherein the SLD detector is configured and operative to use the first and second color measurements to determine liquid water content and droplet diameter distribution for the cloud in which the light signal was directed into by the laser system.

Abstract: Methods of determining a size distribution of water droplets in a cloud are described herein. In some embodiments, a method of determining a size distribution of water droplets in a cloud comprises sampling a depth of the cloud with a beam of electromagnetic radiation, measuring a scattering signal of the electromagnetic radiation returned from the cloud over a range of field of view angles to provide a measured scattering curve [ p total (¸)], removing a portion of the measured scattering curve, replacing the removed portion with an extrapolation of the remaining measured scattering curve to provide an estimated scattering curve, and determining a first estimate droplet size distribution [ n (1) (D)] from the estimated scattering curve.

Abstract: In one aspect, methods of determining a size distribution of water droplets in a cloud are described herein. In some embodiments, a method of determining a size distribution of water droplets in a cloud comprises sampling a depth of a cloud with a 5 beam of electromagnetic radiation, measuring echo intensities of the electromagnetic radiation returned from the cloud with a detector, determining a measured optical extinction coefficient from the measured echo intensities, determining a measured backscatter coefficient from the measured echo intensities, determining a lidar ratio from the measured optical extinction coefficient and the measured backscatter coefficient, 10 determining from the lidar ratio a value pair comprising a shape parameter (p) and median volume diameter (DMVD) of the water droplets, and determining a size distribution of the water droplets using the value pair (pt, DMVD).

Abstract: A method of laser scanning a perimeter zone of a target site for the detection of potential threats comprises: scanning a pulsed laser beam across the perimeter zone; receiving echoes from the pulsed laser beam and forming for a plurality of perimeter zone scans to form scene images. In addition, a method of authenticating a potential threat detected in a perimeter zone of a target site comprises: detecting the potential threat, interrogating the potential threat by a wireless transmission; declaring the potential threat unauthorized if no response is transmitted within a predetermined time interval or if the received response is determined not to comprise the proper access code.

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 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.
