| 英文摘要 | A temperature reference jacket (1) includes an optical absorber (11) for executing calorimetric measurement of optical power to be measured, a heater (11a), a cooler (12), and a temperature sensor (13). The monitor monitors (34) the optical power to be measured. A shutter (33) selectively transmits/shields the optical power to be measured with respect to the optical absorber (11). A memory (4a) stores a first control amount for the cooler (12) corresponding to the optical power to be measured and second and third control amounts for the heater (11a) in advance. A controller (5) controls opening/closing of the shutter (33), reads out the first and second control amounts from the memory (4a) in accordance with the monitoring result from the monitor while the shutter is closed, and reads out the first and third control amounts from the memory (4a) while the shutter (33) is open. The controller (5) finely adjusts a voltage for the heater so that the temperature reference jacket (1) and the optical absorber (11) are set in an isothermal state while the shutter (33) is closed and open, respectively. A data processor (6) calculates the optical power to be measured in accordance with first and second isothermal control amounts for the voltage of the heater when the isothermal state is obtained while the shutter (33) is closed and open, respectively. |
