Abstract: The disclosure extends to methods, devices, and systems for removing speckle from a coherent light source, such as laser light. The methods, devices, and systems help eliminate or reduce speckle introduced from a coherent light source, such as laser light, by utilizing the teachings and principles of the disclosure.

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.

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).
