Full-Field Light Detection and Ranging Imaging System

Apparatuses and methods determine positional information from a reflected optical signal for an object on a per pixel basis. A spread spectrum imaging system includes a transmitting module transmitting a transmitted optical signal that illuminates a target space and contains a transmitted pulse that is modulated with a first pseudo-noise (PN) code. The imaging system includes a receiving module that receives a reflected optical signal from an object. The reflected signal is processed by an optical array that detects a detected signal from the reflected optical signal, where the detected signal contains a plurality of pixels spanning a target space. When the determined PN code corresponds to the selected PN code, image information and the positional information is presented for the object. When different positional information is obtained for different pixels in the image, the imaging system may determine that different objects appear in the received image.

Packaging and alignment methods for optical components, and optical apparatus employing same

Roughly described, a submount has a standoff structure protruding from its surface. An optical component is pressed against the standoff structure until tilt and planar non-uniformities are removed, and then bonded to the submount using an adhesive placed in the wells between the protrusions of the standoff structure. The standoff structure preferably has a total surface area contacting the optical component which is much smaller than the area by which the optical components overlap the submount. The optical component mounted in this manner can be an optical array component (including an optical fiber array), or a component having only a single optical port. A second optical component can be attached to the submount in the same manner, greatly simplifying the vertical alignment problems between the two components.
