Abstract
A method comprises generating a laser signal; scanning the laser signal into a field of view; and processing the return signal.
Claims20
A method comprising:
- generating a continuous wave laser signal;
- frequency encoding the laser signal with the angle of transmission;
- scanning the frequency encoded laser signal into a field of view;
- sensing a return signal;
- and
- imaging the sensed return signal, the image representing the content of the field of view without blind zones.
3 more elements
The method of claim wherein frequency encoding the laser signal with the angle of transmission includes frequency encoding the laser signal with the angle of transmission in azimuth.
A laser apparatus, comprising:
- a transmitter, including:
- a continuous wave laser;
- means for scanning a laser signal generated by the laser into a field or view
- means for encoding the scanned laser signal with the angle of transmission at which it is scanned;
- and
- a receiver, including:
- a single detector from which a reflection of the scanned laser signal can be imaged with no blind zones.
4 more elements
A method, comprising:
- transmitting a laser signal linear frequency modulated over azimuth and frequency encoded with the angle of transmission;
- sensing a return signal;
- and
- processing the sensed return signal to image the field of view based upon the angle of transmission and the linear frequency modulation of the transmitted laser signal.
