Apparatus and method for sensing the position, size, shape and location orientation of one or more objects in two dimensions. The position sensor uses arrays of light sensors mounted on a substrate. When an object passes in proximity to the light sensors light energy from a plurality of light sources is either reflected from the object to the light sensors, or is emitted directly to the light sensors. The light energy is then converted to individual signals and transmitted through circuit traces in a printed circuit board to a local controller. The information may then be processed to determine the size, position, shape and location orientation of an object.

A universal joint between adjacent, electrically connected instrument housings for downhole well operations allow the connected housings to bend longitudinally as required to traverse an arced section of a well bore but does not permit relative elongation or twisting about the longitudinal axis of the housings. I one embodiment, a fluid impermeable open passage space at atmospheric pressure surrounds electrical signal carriers linking the instrument circuitry within the two housings. The passage is constructed as a high-pressure flexible bellows or as a braided or spiral wound high-pressure fluid hose. In another embodiment, a fluid impermeable sheath surrounds the signal carriers and encapsulates the signal carriers by a resilient solid. The articulation structure comprises a Cardan-type of universal joint wherein two fingers project longitudinally from the end of each of the housings. The fingers are meshed and pivotally joined to respective spindles projecting radially from the open center of a ring spyder. The protective bellows, hose or resilient compound filled sheath is secured at opposite ends to bore plugs in the respective instrument housings. Between the instrument housings, the hose, bellows or filled sheath passes through the open center of the spyder ring.

An active optical zoom system changes the magnification (or effective focal length) of an optical imaging system by utilizing two or more active optics in a conventional optical system. The system can create relatively large changes in system magnification with very small changes in the focal lengths of individual active elements by leveraging the optical power of the conventional optical elements (e.g., passive lenses and mirrors) surrounding the active optics. The active optics serve primarily as variable focal-length lenses or mirrors, although adding other aberrations enables increased utility. The active optics can either be LC SLMs, used in a transmissive optical zoom system, or DMs, used in a reflective optical zoom system. By appropriately designing the optical system, the variable focal-length lenses or mirrors can provide the flexibility necessary to change the overall system focal length (i.e., effective focal length), and therefore magnification, that is normally accomplished with mechanical motion in conventional zoom lenses. The active optics can provide additional flexibility by allowing magnification to occur anywhere within the FOV of the system, not just on-axis as in a conventional system.
