Abstract:

The study considers the tradeoffs involved in selecting the excitation power for a pair of fine-wire resistance thermal probes for the measurement of the atmospheric refractive-index structure function constant CN. It is shown that the choice is critical if valid measurements are to be made down to 10 to the minus 8th powerm to the 13 power. The optimum probe excitation found is approximately one microwatt, which is consistent with earlier NRL practice but inconsistent with generally accepted values used elsewhere which range upwards from 10 microwatts.
