Abstract: An endoscope has an improved chip-on-tip configuration that includes both a first configuration of source illumination fibers and a second plurality of source illumination fibers, along with a camera chip. The combination of the camera chip and the source illumination fibers on the tip of the endoscope results in endoscopes with reduced size and weight.

Abstract: Systems and methods for the detection of calculi in the biliary system are disclosed. The systems include an illumination source, one or more filters that filter a first set of illumination photons and a second set of illumination photons, as well as associated processors and detectors. The system is also designed to generates image data sets and generated information related to the location of the calculi.

Abstract: Systems for and methods for in situ optimization of tunable light emitting diode sources are disclosed herein. During operation, the systems and methods obtain real-time feedback from an image sensor, and that feedback is used to tune the tunable LEDs. By tuning the tunable LEDs, the best values for the LED spectral output can be selected based on the feedback from the image sensor, and an image with improved contrast is obtained. Alternatively, the amount of time to obtain an image with acceptable contrast is reduced.

Abstract: Techniques, devices and methods for discriminating a target from a background material without optimizing directly on the target are provided. The devices and methods can generate pass bands of single or multiple wavelengths of variable shape and intensity, and can also select and control the shape of the pass band profiles to improve the detection of targets of interest.

Abstract: Systems for and methods for detecting samples and other compounds of interest are disclosed herein. The system can include an illumination source that is configured to emit light in a variety of different wavelength bands, an optical filter, a camera chip, and an optical path configured to direct the light emitted by the first illumination source at a target and direct the light reflected from the target to the at least one camera chip. The illumination source and the optical filter are transitionable between a first tuning state corresponding to a target tissue and a second tuning state corresponding to a background tissue. The system can be configured to record images at the different tuning states and generate a score image corresponding to the target tissue based on the recorded images.
