摘要：

A new scheme for temperature measurements in a magneto-optical trap is reported. It allows non-destructive on-line measurements of spring constant, friction coefficient, and temperature in a magneto-optical trap. By this method, sub-Doppler temperatures as low as 20 muK have been measured on-line in a rubidium trap.
