Abstract
A medical light source device includes: a first light source configured to emit laser light; a second light source configured to emit measurement light for measuring a connection state between a light guide configured to guide the laser light and an emission optical system configured to irradiate a subject with the laser light through the light guide to the light guide; and a control unit configured to control output of the laser light in the first light source based on return light of the measurement light emitted from the second light source.
Claims20
A medical light source device comprising:
- a first light source configured to emit laser light;
- a second light source configured to emit measurement light for measuring a connection state between a light guide configured to guide the laser light and an emission optical system configured to irradiate a subject with the laser light through the light guide;
- an optical measurement device configured to measure the connection state by using an optical time domain reflectometer (OTDR), the optical measurement device including the second light source and being configured to generate an OTDR waveform indicating a light amount level of the return light with respect to a distance from the medical light source device;
- and
- a control circuit configured to control output of the laser light in the first light source based on information indicating a peak in the OTDR waveform.
A medical observation system comprising:
- a medical light source device configured to emit laser light;
- a light guide configured to guide the laser light;
- an optical measurement device configured to measure the connection state by using an optical time domain reflectometer (OTDR), the optical measurement device including the second light source and being configured to generate an OTDR waveform indicating a light amount level of the return light with respect to a distance from the medical light source device;
- and
- an emission optical system configured to irradiate a subject with the laser light through the light guide,
- wherein the medical light source device includes:
- a first light source configured to emit the laser light;
- a second light source configured to emit measurement light for measuring a connection state between the light guide and the emission optical system;
- and
- a control circuit configured to control output of the laser light in the first light source based on information indicating a peak in the OTDR waveform.
A method for controlling a medical light source device including a first light source for emitting laser light and a second light source, the method comprising:
- emitting, from the second light source, measurement light for measuring a connection state between a light guide configured to guide the laser light and an emission optical system configured to irradiate a subject with the laser light;
- measuring the connection state by using an optical time domain reflectometer (OTDR), the optical measurement device including the second light source and being configured to generate an OTDR waveform indicating a light amount level of the return light with respect to a distance from the medical light source device;
- and
- controlling output of the laser light in the first light source based on information indicating a peak in the OTDR waveform.
