Detection system with a single mode laser for a vehicle

A detection system for a vehicle, comprising:

• an imaging device configured to capture an image in a field of view of an interior surface of the vehicle;
• an illumination assembly configured to illuminate the field of view with a structured light pattern, the illumination assembly including:
• a plurality of vertical-cavity surface-emitting laser diodes (“VCSELs”) arranged in a laser diode array and configured to project a plurality of illuminations;
• and
• at least one optical element configured to collimate the plurality of illuminations into the structured light pattern having a plurality of light spots;
• and
• a processor in communication with the imaging device and the illumination assembly, the processor configured to communicate a signal to operate the laser diode array, process the image of the interior surface to determine a position of plurality of light spots in the structured light pattern, and extract a depth of the interior surface based on the position of the plurality of light spots.

A detection system, comprising:

• an imaging device configured to capture an image in a field of view of a surface of an object;
• an illumination assembly configured to illuminate the field of view with a spot array pattern, the illumination assembly including:
• a plurality of single mode lasers arranged in a laser diode array and configured to project a plurality of illuminations;
• and
• an optical element configured to collimate the plurality of illuminations into at least one light spot;
• and
• a processor in communication with the imaging device and the illumination assembly, the processor configured to communicate a signal to operate the laser diode array, process the image of the surface of the object to develop a baseline amount of vibrations based on environmental factors, to detect a change in a speckle content of the at least one light spot in the spot array pattern outside of the baseline, and identify a condition of the object based on the detected change in the speckle content outside of the baseline.
