    摘要: Multiple laser optical sensing systems and methods for detecting target characteristics are disclosed. The present invention detects the presence of an object in a monitored area using an laser-based object detection system and may selectively cause a controlled response when an object is detected. At least two laser signals may be emitted into a monitored area using a vertical cavity surface emitting laser structure. At least one detector receives any laser signals not blocked by an object. The system determines the presence or absence of an object in the environment using a microprocessor and determines the objects characteristics by comparing received laser signals associated with it to object characteristics stored in a memory. The system may selectively causing a controlled response in accordance with the determination of object characteristics and/or correlating response criteria.

    摘要: A method and system for coupling a laser (e.g., vertical cavity surface emitting laser (VCSEL)) to an optical fiber is disclosed. A plurality of optical modes associated with a laser, e.g., a VCSEL, are scrambled, and radiation from the VCSEL can be focused on a fiber facet associated with the optical fiber. Thereafter, the VCSEL can be coupled to the optical fiber to thereby improve coupling repeatability while reducing mode selective coupling of the VCSEL to the optical fiber. The optical modes can be scrambled utilizing an optical scattering surface. Such an optical scattering surface can produce a Lambertian-like scattering source such that optical modes thereof are combinable to form a plurality of optical modes. The VCSEL can be coupled to said optical fiber by butt-coupling said optical fiber to the multimode VCSEL through a receiver formed in a housing for the VCSEL and/or by utilizing at least one lens for imaging radiation/signals onto a particular spot. Additionally, such a spot generally comprises a size larger than a core of said optical fiber to thereby reduce coupling variations thereof. The optical modes may also be scrambled utilizing an optical concentrator configured as a linear, conical, parabolic, or other shaped concentrator, which can be adapted for use in mixing optical modes. The optical modes can also be mixed utilizing an optical scattering surface to provide a Lambertian-like scattering source.
