Light Source, Method for Controlling Light Source, and Method for Replacing Light Source
First Claim
1. A method for controlling a light source constructed from a plurality of laser diodes, comprising:
- for each pair consisting of any one of said plurality of laser diodes and a control board dedicated to said one laser diode to control light output of said one laser diode, generating in advance calibration data that defines a correspondence between a control value for driving said control board and a value representing the actual light output of said one laser diode measured when said control board is driven based on said control value; and
controlling overall light output of said light source based on said calibration data generated for said each pair.

Abstract
In a light source constructed from a plurality of laser diodes, the overall light output of the light source is controlled based on calibration data which is generated for each pair consisting of any one of the plurality of laser diodes and a dedicated control board for controlling the light output of the one laser diode, and which defines a correspondence between the control value for driving the control board and the value of the light output of the laser diode measured when the control board is driven based on the control value, and when replacing a designated one of the laser diodes in the light source, the designated laser diode and its dedicated control board are replaced together with the corresponding calibration data.

7. A method for replacing a designated one of said plurality of laser diodes, for use with a light source constructed from a plurality of laser diodes, wherein
said designated laser diode to be replaced and a control board dedicated to said designated laser diode to control light output of said designated laser diode are respectively replaced with a new laser diode and a new control board dedicated to said new laser diode to control light output of said new laser diode, and among calibration data which, for each pair consisting of any one of said plurality of laser diodes and a control board dedicated to said one laser diode to control the light output of said one laser diode, defines a correspondence between a control value for driving said control board and a value representing the actual light output of said one laser diode measured when said control board is driven based on said control value, said calibration data being used for controlling overall light output of said light source, the calibration data that has been used for controlling the light output of said designated laser diode is replaced with the calibration data generated for the pair consisting of said new laser diode and said new control board dedicated to said new laser diode to control the light output of said new laser diode.
