A system for material excitation in microfluidic devices is described. Aspects of the invention resemble a submerged periscope when in use. They allow for light to be redirected along a more advantageous trajectory as does the maritime device. A prism with a reflecting surface may be used to direct a laser beam along one or more microfluidic trenches or channels. Alternatively, a reflecting surface may be provided in connection with a simple support. Directing a beam along multiple paths is preferably accomplished by scanning a single laser across or around the reflecting surface provided. Provision may be made for at least a portion of the submersible used to function as an electrode to assist in electrokinetically driving fluids and / or ions within the microfluidic device.

An iris imaging system used for biometric identification provides a combined iris imager and wavefront sensor. The detector array allows for independent readout of different regions, such that a wavefront sensor region can be read out fast while allowing signal to integrate on the iris imaging region. Alternatively, the entire array may be used for wavefront sensing during an acquisition phase, and then at least a portion of the array may be switched to be used for iris imaging during a subsequent imaging phase. An optical periscope optionally allows various optics to be inserted in front of the combined iris imager and wavefront sensor. In another embodiment, the glint image of an on-axis or near on-axis illumination source is picked off at the image plane and directed to the wavefront sensor optics, while allowing all of the light from the iris field to pass through to the iris imaging camera.

Periscope Swim Goggles are swimmer's goggles with a periscope situated above the water line that projects the view that is ahead of the swimmer through a fiber optic cable to a viewer located on the goggle's eyepiece. Generally, an open-water swimmer using the free style or crawl stroke must occasionally sight on a landmark to swim toward. Periscope Swim Goggles would enable the swimmer to continually swim directly along the desired path without lifting the head for sighting. Conventional swimming goggles are typically comprised of two eyepieces contoured and gasketed for an air-tight fit around each eye socket and an elastic strap that wraps around the head holding the eyepieces tight to the face. In one embodiment of the invention, the periscope is positioned and secured at the back of the head by the elastic strap of the goggles. The fiber optic cable leaves the periscope and follows the elastic strap to the viewer which is mounted to the front of the eyepiece.

A see-through periscope for sighting-in optical sights or open sights by co-aligning one type of sighting system with the other type. The small see-through periscope is preferably used with firearms that have two conditions: (1) the rifle must be equipped with open sights, and (2) a gap must exist between the front of the optical sight and the rear open sight where the periscope can be mounted. Four unique mounts allow the periscope to be used with both magnifying or non-magnifying optical sights of different types, sizes, and shapes and open sights of different heights. The mounts position the bottom mirror at the height of the open sights and the top mirror at a point higher than the optical sight. The bottom mirror captures an image of the open sights aimed at a target and reflects that image to the top mirror, which in turn reflects the image across the top of the optical sight and into the eye of the shooter. The optical sight can still be used because the periscope mounted in front of it has no front or back panels, leaving a window for the shooter to see through the optical sight.
