Abstract
An intelligent endoscopic light source system for controlling the intensity of a light source, including a light source emitting light at a first intensity, an attenuator positioned to receive light from the light source at a first intensity and movable to pass light from the light source at a second intensity, a sensor mounted to the attenuator for measuring the first intensity, and a controller for receiving the intensity measurement from the sensor and moving the attenuator to pass light at a desired second intensity.
Claims21
An endoscopic light source system, comprising:
- a light source emitting light at a first intensity;
- an attenuator positioned to receive light from said light source at the first intensity and movable to pass light from said light source at a second intensity;
- a sensor mounted to said attenuator for measuring the first intensity;
- and
- a controller for receiving the intensity measurement from the sensor and moving said attenuator to pass light at the second intensity.
An endoscopic light source system, comprising:
- a light source emitting light at a first intensity and having a light output path;
- an attenuator having a control path for variably passing light from said light source at a second intensity and a sensor module mounted to said attenuator, the sensor module having a light intensity sensor for measuring the first intensity, the control path and the sensor module positionable in the light output path;
- a controller for receiving the first intensity measurement from the sensor module when the sensor module is in the light output path;
- said controller positioning said attenuator to a location on the control path in the light output path in order to adjust the second intensity based at least in part upon the first intensity of said light source.
