Claim 0:
1. A laser-based ophthalmological surgical system, comprising:
a radiation source configured to emit therapeutic radiation, the therapeutic radiation including a discrete pulse that has a particular pulse frequency and an amount of pulse energy corresponding to a dosage of the therapeutic radiation;
one or more optical elements configured to direct the therapeutic radiation to a targeted area of an eye of a patient, wherein a temperature of the targeted area depends on the dosage of the therapeutic radiation; and
a detector system configured to measure thermal radiation emitted by the targeted area responsive to exposure to the therapeutic radiation, wherein the detector system includes a first detector configured to detect thermal radiation at a first wavelength and a second detector configured to detect thermal radiation at a second wavelength shorter than the first wavelength, wherein the one or more optical elements are configured to optically couple the detector system to the targeted area,
wherein the radiation source emits a plurality of therapeutic radiations to one targeted area, and the detector system measures thermal radiation at a certain time for each of the plurality of therapeutic radiations, the certain time having a defined time delay from an emitting time of each of the plurality of therapeutic radiations and corresponding to a thermal response of the one targeted area,
wherein the first wavelength corresponds to a first temperature lower than a target temperature threshold, and the second wavelength corresponds to the target temperature threshold,
wherein at least one of the first wavelength or the second wavelength is in a range from 1000 nm to 2000 nm, and
wherein the temperature of the targeted area is determined based on both thermal radiation detected by the first detector and the thermal radiation detected by the second detector.
