摘要： A prism array light redistribution apparatus for an eye imaging system including light transmitting fibers, light receiving fibers, and a micro prism array optically coupled to bridge the light transmitting fibers and the light receiving fibers. The array may be further configured to receive light having a bell-shaped angular distribution from the light transmitting fibers and refract the received light to enter the light receiving fibers such that a square-shaped angular distribution of light emits from a light emitting end of the light receiving fibers.

摘要： An eye-imaging apparatus and system is described including arrayed optical fibers having a high numerical aperture and circular fiber array ends arranged at skewed angles relative to the optical axis of the imaging path. Circular fiber array ends are arranged to emit the illumination light into an eye at a skewed angle and a light intensity distribution converter along the illumination path to convert a bell-shaped distribution into a top-hat distribution. As a result, illumination uniformity on the retina of the eye is improved.

摘要： A phototherapy system and device is disclosed, including an array of light sources from at least two distinct spectral light regions. The first spectral light region represents the treatment color, and thus is chosen for its phototherapeutic value. For instance, blue light may be the treatment color for hyperbilirubinemia. The second spectral light region represents the balancing color, and is chosen for its ability to mitigate discomfort that may be caused by viewing the treatment color. When blue is the treatment color, yellow has been found to be an effective balancing color.

The system includes at least one wireless sensor and a monitoring device which are linked to one another of a wireless fashion for measuring physiological signals of a patient. The at least one wireless sensor is located on the patient and may comprise a wireless surface electrode assembly or a wireless needle assembly. The system may also comprise a wireless stimulator synchronized with the wireless sensor for performing certain diagnostic tests, such as nerve conduction velocity tests, for example. The wireless sensor preferably includes active, reference and common conductors. The common conductor can be used to measure the common mode voltage of the patient in the vicinity of the testing, and this voltage can then be subtracted from the measured active and reference voltages.
