  • Laser rangefinder and method for digital signal processing thereof
    Patent number: 8103059
    Abstract: A method for digital signal processing is disclosed. Reflected laser signals are received and digitized to generate corresponding digital signals. The digital signals are accumulated to generate an accumulated signal. A digital filtering operation is applied to the accumulated signal to generate a filtered signal. A maximum signal value for the filtered signal is found and a threshold value is set accordingly. It is determined whether the maximum signal value is less than the threshold value, and, if not, a distance value is calculated.
    Type: Grant
