Abstract
A positioning system is designed to align a lens barrel with a sensor assembly. A first end of a lens barrel includes ridges along an edge. The sensor assembly includes a recessed channel with reciprocal ridges for mating with the ridges of the lens barrel. The sensor assembly also includes a plurality of shim platforms structured, each structured to position a wedge shaped shim, the wedge shaped shim including a flat bottom to slide on the shim platform and raise or lower the lens barrel relative to the reciprocal ridges on which the lens barrel rests.
Claims20
An integrated image sensor and lens assembly comprising:
- an image sensor;
- an image sensor assembly comprising:
- a housing comprising a recessed channel to partially enclose the image sensor, a plurality of ridges, and a plurality of shim platforms, each shim platform structured to position a shim, each shim having a flat bottom to slide along the shim platform;
- and
- a lens barrel having a first portion extending into the recessed channel, the first portion having a plurality of notches configured for mating with reciprocal ridges,
- the plurality of shims, when slid along the shim platform, moving the lens barrel relative to the reciprocal ridges.
An image sensor assembly comprising:
- a lens barrel having a first portion extending into a recessed channel, the first portion having a plurality of notches;
- and
- a housing comprising the recessed channel having a plurality of ridges, the plurality of ridges configured for mating with the plurality of notches, the housing further comprising a plurality of shim platforms, each shim platform structured to receive a shim, each shim having a flat bottom to be movable along the shim platform to move the lens barrel relative to the ridges.
An image sensor assembly comprising:
- a lens barrel having a first portion extending into a recessed channel, the first portion having a tapered end configured to reciprocally mate with a countersink surface;
- and
- a housing comprising the recessed channel having the countersink surface along an outermost portion of the recessed channel, the housing further comprising a plurality of shim platforms embedded among the countersink surface, each shim platform having an inner portion and an outer portion and structured to receive a shim, a bottom of each shim further structured to be movable on the shim platform towards an inner portion or outer portion of the shim platform to raise or lower the lens barrel relative to the countersink surface.
