  • Patent number: 10299732
    Abstract: The disclosure extends to methods, devices, and systems for removing speckle from a coherent light source, such as laser light.

  • Publication number: 20190133416
    Abstract: The disclosure extends to methods, systems, and computer program products for detecting whether an illumination source of an endoscope is in use (inside the body of a patient) versus not in use (outside the body of a patient). The disclosure relies on the fact that the working environment is lit solely by the endoscope and its components. Thus, communication between the illumination or light source controller and the imaging device, such as a surgical camera, is required. When the illumination or light source is turned off and the endoscope is outside the body, a sensor will detect ambient light alerting the illumination source controller that it is outside the body, which then keeps the illumination source off or at a low intensity level. Conversely, when the illumination source is turned off and the endoscope is inside the body, the sensor will not detect any light (or will detect only a very low level of light).

  • Publication number: 20190133427
    Abstract: The disclosure relates and extends to a light source having a strobing or pulsing sequence suitable for use with a CMOS sensor that does not require, have, or use a global shutter. Instead, the CMOS sensor synchronizes the strobing input with the blanking portion of the sensor readout pattern and disables the strobing during sensor readout, or when the strobing would otherwise leave artifacts in the image. The CMOS sensor freezes its readout during the strobing.

  • Publication number: 20180177388
    Abstract: The disclosure relates to an endoscopic system. The system may include a single optical fiber. The system may further include a light source which transmits light into the single optical fiber. An image sensor may be provided within the endoscopic system and disposed at a distal end of the single optical fiber. The endoscopic system may be additionally fitted with a diffuser on the distal end of the single optical fiber which outputs a light cone that is broader than an output of the single optical fiber without the diffuser.

  • Publication number: 20180183981
    Abstract: The disclosure relates to an endoscopic system that includes an image sensor, an emitter and an electromagnetic radiation driver. The image sensor includes a pixel array and is configured to generate and read out pixel data for an image based on electromagnetic radiation received by the pixel array. The pixel array includes a plurality of lines for reading out pixel data. The pixel array also has readout period that is the length of time for reading out all the plurality of lines of pixel data in the pixel array. The emitter is configured to emit electromagnetic radiation for illumination of a scene observed by the image sensor. The electromagnetic radiation driver is configured to drive emissions by the emitter. The electromagnetic radiation driver includes a jitter specification that is less than or equal to about 10% to about 25% percent of the readout period of the pixel array of the image sensor.

  • Publication number: 20180177387
    Abstract: The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.

  • Patent number: 9777913
    Abstract: An embodiment of an illumination system for use with an endoscope includes a laser source comprising laser light emitters, an electromagnetic sensor embedded within the laser source to sense light energy, and a control circuit in electronic communication with the electromagnetic sensor and at least one emitter. The control circuit is configured to cause the laser source to pulse light between pixel readout periods. The electromagnetic sensor receives light from at least one emitter and measures an amount of electromagnetic energy generated by at least one emitter. The control circuit controls a duty cycle of the emitters based on a predetermined, known output and in response the amount of electromagnetic energy generated by at least one of the emitters and obtains a desired exposure response for images captured by the image sensor.
