Abstract: A camera including a lens barrel, lens elements, and an image sensor. The lens barrel includes a first subsection, a second subsection, and a spacer located between the first subsection and the second subsection. The lens elements are located in the first subsection and other lens elements located in the second subsection. The image sensor is aligned along an optical axis that extends through the first subsection and the second subsection of the lens barrel. The first subsection and the second subsection are separate pieces that are in communication by the spacer being sandwiched between the first subsection and the second subsection.

Abstract: A continuous slanted edge focus measurement system characterizes focus of a camera lens. The measurement system may be used to measure effects on focus on caused by factors such as thermal focal shift, humidity focal shift, focal shift caused by changing parts in the camera, and focal shift by changing the camera design. An accurate measurement system enables camera designers to optimize focus under a variety of different conditions and ensure consistency in the products.

Abstract: An integrated image sensor and lens assembly comprises a lens barrel holding camera lenses coupled to a lens mount. The lens mount is further coupled to an image sensor substrate that has an image sensor lying on an image plane. The optical distance between lenses and the image sensor is tuned such that the focal plane of the lenses coincides with the image plane. Due to thermal expansion, this optical distance may vary thereby to cause the focal plane of the lenses to shift away from the image plane. The integrated image sensor and lens assembly further comprises spacers that couple one or more lens elements to the lens barrel. The spacers and the lens elements are configured such that the optical distance is maintained to be constant or substantially constant.

Abstract: An integrated image sensor and lens assembly comprises a lens barrel, an adapter tube, and a lens mount. The lens mount includes a first thread having a first pitch and the tube adapter comprises a second thread reciprocal to the first thread. The first and second threads secure the tube adapter within the lens mount. The tube adapter further comprises a third thread having a second pitch different than the first pitch, and the lens barrel comprises a fourth thread reciprocal to the third thread. The third and fourth threads secure the lens barrel within the tube adapter. A rotation of the tube adapter with respect to the lens barrel and the lens mount causes linear movement of the lens barrel and the lens mount with respect to the tube adapter in a same direction along the optical axis.

Abstract: A device and method for three-dimensional (3-D) imaging using a defocusing technique is disclosed. The device comprises a lens, a central aperture located along an optical axis for projecting an entire image of a target object, at least one defocusing aperture located off of the optical axis, a sensor operable for capturing electromagnetic radiation transmitted from an object through the lens and the central aperture and the at least one defocusing aperture, and a processor communicatively connected with the sensor for processing the sensor information and producing a 3-D image of the object. Different optical filters can be used for the central aperture and the defocusing apertures respectively, whereby a background image produced by the central aperture can be easily distinguished from defocused images produced by the defocusing apertures.
