LIGHT SOURCE DEVICE AND CALIBRATION DEVICE

To provide a light source device capable of performing an optical output control with high responsibility.SOLUTION: A light source device comprises: a light-emitting device; a temperature detector that detects a temperature at an installation location of the light-emitting device; a driving circuit supplying current to the light-emitting device; a control part that controls the current supplied to the light-emitting device from the driving circuit; and a target light output reception part that receives an input of information corresponding to a target value Φ of light output of the light-emitting device. The control part comprises: a first storage part in which a control function for calculating a third variable number correlated to the current supplied to the light-emitting device from a first variable number correlated to a temperature at the installation location of the light-emitting device and a second variable number correlated to the light output of the light-emitting device; and an arithmetic processing part that reads out the control function from the first storage part, substitutes a temperature T and the target value Φ into the first variable number and the second variable number in the control function, and determines a supply current amount for the light-emitting device as the third variable number.SELECTED DRAWING: Figure 2 【課題】応答性の高い光出力制御が可能な光源装置を提供する。【解決手段】本発明に係る光源装置は、発光素子と、発光素子の設置箇所の温度を検出する温度検出器と、発光素子に対して電流を供給する駆動回路と、駆動回路から発光素子に供給する電流を制御する制御部と、発光素子の光出力の目標値Φに対応する情報の入力を受け付ける目標光出力受付部とを備える。制御部は、発光素子の前記設置箇所の温度に相関のある第一変数、及び発光素子の光出力に相関のある第二変数から、発光素子に供給される電流に相関のある第三変数を求める制御関数が記録された第一記憶部と、第一記憶部から制御関数を読み出すと共に、温度Ｔ及び目標値Φを制御関数内の第一変数及び第二変数に代入して、第三変数である発光素子に対する供給電流量を決定する演算処理部とを備える。【選択図】図２
