Abstract: According to some embodiments, a pressure tolerant camera system includes: an enclosure filled with an incompressible fluid and having a viewport through which light can pass; a digital image sensor provided within the enclosure; and a plurality of mirror lenses provided within the enclosure and arranged to reflect light from the viewport onto the digital image sensor.

Abstract: Particle detection systems without knowledge of a location and velocity of a particle passing through a volume of space, are less efficient than if knowledge of the particle location is known. An embodiment of a particle position detection system capable of determining an exact location of a particle in a fluid stream is discussed. The detection system may employ a patterned illuminating beam, such that once a particle passes through the various portions of the patterned illuminating beam, a light scattering is produced. The light scattering defines a temporal profile that contains measurement information indicative of an exact particle location. However, knowledge of the exact particle location has several advantages. These advantages include correction of systematic particle measurement errors due to variability of the particle position within the sample volume, targeting of particles based on position, capture of particles based on position, reduced system energy consumption and reduced system complexity.

Abstract: A technique for attaching an optical element to a structural element is disclosed. In one particular exemplary embodiment, the technique may be realized as an optical element mounting apparatus. Such an apparatus may comprise a base structure, a first mounting pad located on a first flexure formed in the base structure, a second mounting pad located on a second flexure formed in the base structure, and a third mounting pad located on the base structure, wherein the first, second, and third mounting pads support an optical element mounted thereon.
