Abstract
Laser optical sensing systems and methods for detecting object characteristics are disclosed. The system includes a laser source with at least two emission apertures from which laser signals are emitted. The system also includes at least one detector, which is operationally responsive to the laser source. The system can also include a microprocessor that is operationally coupled to the detector(s) for processing signal data, a memory accessible by the microprocessor for storing object characteristics (e.g., unique signals), and a software module accessible by the microprocessor for enabling system training and detection operations. The laser source emits into an environment at least two laser signals, one from each emission aperture. The detector detects the laser signals after the signals pass through the environment, which is occupied by an object, and the microprocessor determines object characteristics based on the matching of laser signals received by the detector(s) and characteristics stored in memory.
