Patent ID: 8820645

Claim:
A scanning device, comprising: a laser source emitting a laser scanning beam; a movable scanning mirror reflecting the laser scanning beam to project an object scan beam towards an object to be scanned; a mirror moving element moving the movable scanning mirror; a controller receiving an input corresponding to a range estimate from the scanning device to the object and adjusting characteristics of the object scan beam setting of the scanning device based on the range estimate, wherein the object scan beam is generated when the laser scanning beam is emitted from the laser source; a receiver receiving a scan signal of the object and having a receiver bandwidth, the receiver being configured to pass electrical signals in a range of frequencies corresponding to the receiver bandwidth; and wherein the controller is configured for further adjusting the receiver bandwidth of the receiver and a scan amplitude of the mirror moving element based upon the received input corresponding to the range estimate based on a gain measurement of an initial scan of the object.
