摘要： PROBLEM TO BE SOLVED: To perform temperature control that securely minimizes noise even within a relatively wide variation range of a drive current. SOLUTION: While the drive current is varied, light intensity and the level of noise are measured, and temperatures at which the noise does not become larger than an allowable value within a variation range or a wider range than that of the drive current predicted to be generated in long-time continuous operation during use are found out and stored; when a target value of the light intensity is given, a temperature command is determined on the basis of a temperature stored associatively with the target value to perform the temperature control. The temperature control that securely minimizes the noise can be performed even within the relatively wide variation range of the drive current during the use. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To control temperature so as to reliably minimize noise even within the comparatively wide change range of a driving electric current. SOLUTION: A light intensity and the loudness of the noise are measured, while changing the driving electric current. The temperature for allowing the noise not to be louder than a permission value is obtained and stored within the change range of the driving electric current which is predicted to be generated during a long-term continuous operation in use, or within the control range of the driving electric current which is larger than the change range. When the target value of the light intensity is given, a temperature command is determined based on the temperature stored in response to the target value, so as to control the temperature. Consequently, the temperature control to reliably minimize the noise is performed even within the comparatively wide change range of the driving electric current in use. COPYRIGHT: (C)2007,JPO&INPIT
