1. A method for automatically controlling treatment of tissue with optical pulses, comprising:
- irradiating a first site in a portion of tissue with a first optical pulse;
following the irradiation, automatically making a measurement of a tissue property at the first site;
based on the measurement, automatically adjusting a parameter of a second optical pulse according to an algorithm selected from the group consisting of a moving simplex algorithm, a neural net algorithm, and a fuzzy logic algorithm;
irradiating a second site in the portion of tissue with the second optical pulse in order to provide treatment of the tissue at a pre-determined treatment level;
irradiating other sites in the portion of tissue with other optical pulses;
following the irradiation, automatically making measurements of the tissue property at the other sites; and
taking a weighted average of the measurements,wherein the step of automatically adjusting the parameter of the second optical pulse is based on the weighted average of the measurements.

Abstract
Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.
