A camera module includes a lens assembly, a lens holder, and an image sensor assembly. The lens assembly includes a lens barrel and multiple lens elements embedded within the lens barrel. A change of temperature causes an optical focal shift that is determined according to an optical thermal shift rate associated with an optical design of the lens assembly. The lens holder has a lens holder CTE to compensate for the optical focal shift by thermo-mechanical expansion. The change of temperature causes a length expansion of the lens holder determined at least in part according to the lens holder CTE. The image sensor assembly includes an image sensor and a substrate coupled to the image sensor, the image sensor to capture light passing through the multiple lens elements and convert the captured light into image signals. The lens holder is attached to the lens barrel and the substrate using adhesives.

Apparatus and methods for measuring a position of a point on a submerged surface. The apparatus includes: a platform; a liquid-tight pressure vessel fixedly coupled to the platform, wherein the liquid-tight pressure vessel is formed in part by an optically transparent enclosure; a pan-tilt mechanism coupled to the platform and disposed inside the liquid-tight pressure vessel; a camera mounted to the pan-tilt mechanism; a laser range meter affixed to the camera; and a refractive index sensor coupled to and disposed outside the liquid-tight pressure vessel. In accordance with one proposed implementation, the optically transparent enclosure is spherical, the pan-tilt mechanism has a pan axis and a tilt axis that intersect at a center of the optically transparent enclosure, and the laser range meter is located to emit a laser beam that is perpendicular to the optically transparent enclosure.

The first and second modules are identical, symmetrical, and each include, respectively, a main vessel connected to a first or second liquid tank, respectively, an outer ballast vessel capable of moving into the main vessel, an inner ballast vessel capable of moving into the ballast vessel, a ballasted skirt that is suspended on said outer ballast vessel, and is capable of vertically opening out or closing, and first and second transmission devices for transmitting the movement of the outer and inner ballast vessels to alternators.

A camera L-plate fixture for use with a camera comprising a base plate, a side plate and a retained connection holding the side plate an adjustable space from the base. The base plate comprising a first rod chamber, a second rod chamber, a first and second base screws in the base extending into the first and second rod chambers respectfully. The side plate adjustably attached to the base plate with the retained connection. The retained connection further comprising a pair of parallel rods slidably in the base and connected to the side plate. flat on each rod allows a respective screw in the base to limit travel of the rods to the range of the screws spaced from the respective flat. A header on the end of each rod bears against the screw to limit travel.
