Schedule AssistantTM: A Portable Visual/Audio Prompting System for Enhancing Independence and Self-Determination in Personal Scheduling and Time Management for Individuals with Mental Retardation

Not Available Long-range, non-cooperative identification techniques such as one-dimensional shape echoes require sources that are compact, eyesafe and produce temporally short pulses to provide fast accurate target identification in the field. To meet these requirements, CTI proposes a solid state Raman laser (SSRL) with an innovative architecture that produces 1.5 um output in short 1 ns length pulses. This architecture is calculated to compress the pump laser pulse by factors of five or greater thereby eliminating the need for short pulse pump lasers. Moreover, this Raman laser provides beam cleanup, efficiently converting and improving the spatial beam quality of the pump laser. The pump laser design is based on previous work at CTI and is a rugged, efficient design suited for pumping this SSRL. The architecture can also be modified to produce adaptive waveforms such as the pulse doublet, permitting microDoppler and wind measurement capability with the same transmitter and therefore multipurpose instrument capability. This program will tie together our experience in flightworthy lidar systems with recent advances in SSRLs. The proposed effort will model and design the 1ns transmitter, produce 1 ns long pulses by compression of the pump pulses in a lab demonstration, and perform a preliminary transceiver design.
