摘要： A dual optical path rotary joint provides a low friction coupling of optical fiber connections for optogenetic research and other applications. Two optical paths are provided through the rotary joint which are rotation-insensitive. The ends of the rotary joint rotate with respect to a common housing, which may be provided with ball-bearings or other suitable low-friction rotational mounts in which a first rotating component and a second rotating component are secured. The first and second rotating components are not mechanically linked in rotation, and their rotation is only synchronized by magnets disposed on the first rotating component and the second rotating component. A pair of optical fibers is coupled to the first rotating component and another pair of optical fiber is coupled to the second rotating component. A pair of isolated optical paths links the pairs of fibers, which are directed between the first and second rotating components by reflection.

摘要： A pumped fluorescent light source includes a parabolic mirror that is positioned to focus pumping light from one or more pump sources on a fluorescent body. The resulting assembly provides for heat collection from a back surface of the light source for both the fluorescent body and the pumping sources in a compact package that may be hermetically sealed. The parabolic mirror has reflective surfaces disposed outside of a collection area of an output beam of the light sources, so that the collection area is not obstructed by the parabolic mirror. The light source also includes a collecting lens for collecting the light emitted by the body. The parabolic mirror focuses the stimulus light on the fluorescent body to stimulate emission. An additional parabolic mirror may be included behind the fluorescent body to focus the fluorescent emissions that do not directly enter the collection area at a point of collection.

摘要： A hybrid rotary joint provides both optical and fluid channels for applications such as optogenetic research. The rotary joint has a stationary component and a rotating component. The optical channel and fluid channel permit simultaneous and rotation-insensitive passage of light and fluid from the stationary to the rotating side of the hybrid rotary joint. The input to the optical channel is provided via an input optical fiber and the input to the fluid channel is fluid from a fluid source. The outputs are an optical fiber output and a fluid channel output. As light passes from the stationary side to the rotating side of the hybrid rotary joint, it is deflected off a beam deflector having an angular orientation that is passively aligned and made independent of the angular orientation of the rotating component via the interaction between magnets attached to each of the beam deflector and the stationary component.

摘要： A cannula can have a ferrule with two interspaced optical fiber passages extending therebetween, each securely housing an optical fiber therein having a first tip exposed at a connection end, and a second tip protruding from an opposite implant end by a penetration distance, and a bore extending into the ferrule from the connection end. The cannula can be removably connected by a patch cord having a ferrule with a guide pin, with a relatively high degree of optical alignment, by inserting both ferrules into corresponding ends of a sleeve and engaging the guide pin within the bore.

摘要： A optical system and imaging device provide simultaneous or sequential optogenetic stimulation of different locations within a biological sample and fluorescence imaging of the locations. The systems include an illumination array with multiple electrically addressable elements that select a spatial pattern of illumination, an optical fiber bundle with fibers coupled between the array element and target locations at the sample, a fluorescence illumination source, and an imaging system for measuring fluorescence returning from the target locations. The optical imaging devices include a housing and a sample connector configured for receiving a first optical fiber bundle connection including multiple optical fibers. The sample connector has an indexing feature to maintain a fixed relationship between the fibers and internal optical paths of the device. The imaging devices also include an indexed input connector to receive another fiber bundle that carries the stimulus pattern, and a fluorescence excitation input connector.

摘要： A multi-site fluorescence recording system provides simultaneous monitoring of cell activity in different brain regions of a freely moving animal. The system includes an electrical rotary joint that couples signals to and from an external data acquisition and control unit connected to a stator of the rotary joint, which releases twisting of the optical fibers connected to the animal. Electrical signals are coupled to one or more fluorescence stimulation/detection units on the rotor of the rotary joint. The fluorescence stimulation/detection units receive one or more connections from optical fibers that connect the stimulation/detection unit(s) to the different brain sites. The rotating stimulation/detection units include spectral filters to separate the excitation light from the fluorescence signal, light sensors (an image sensor or photodiodes) and excitation light sources.

摘要： A miniaturized microscope having a tunable focal length provides for fluorescence measurements at an adjustable focus, providing for autofocus and/or depth adjustment of an image measurement without altering or adjusting a probe implanted in a sample and while providing collimated illumination of an area within the sample. The microscope includes an objective lens having a fixed position with respect to a second connector for receiving light returning from the sample and focusing it on an image sensor within the microscope that generates an image output, a beamsplitter for separating light returning from the sample, and an electrically-tunable lens positioned between the objective lens and the image sensor for adjusting an optical path length from the optical interface to the image sensor. The illumination is focused at or near a back focal plane of the objective lens to the sample, providing collimated or quasi-collimated illumination on or within the sample.
