In some examples, a laser-based ophthalmological surgical system (hereinafter 'system') includes a therapeutic radiation source configured to emit therapeutic radiation with a first wavelength. The system may also include a probe radiation source configured to emit probe radiation with a second wavelength different than the first wavelength. The system may also include one or more optical elements configured to direct the therapeutic radiation and the probe radiation into an eye of a patient and to collect reflected probe radiation from the eye of the patient. The reflected probe radiation may be indicative of an amount of therapeutic radiation exposure of the eye of the patient. The system may also include a photodetector configured to receive the reflected probe radiation from the one or more optical elements and to generate a photocurrent indicative of the amount of therapeutic radiation exposure of the eye of the patient.

Radiation dosimetry systems and methods

In some examples, a laser-based ophthalmological surgical system (hereinafter 'system') includes a therapeutic radiation source configured to emit therapeutic radiation at a first intensity during a therapeutic portion and to emit probe radiation with a second intensity which is less than the first intensity during a probe portion. The system may also include one or more optical elements configured to direct the therapeutic portion and the probe portion into an eye of a patient and to collect reflected radiation from the eye of the patient. The reflected radiation may be indicative of dynamics of microbubbles in the cells of the eye of the patient.

Enhancing optical detection of micro bubbles by laser pulse expansion

In some examples, a laser-based ophthalmological surgical system includes a therapeutic radiation source, one or more optical elements, and a detector system. The therapeutic radiation source may be configured to emit therapeutic radiation. The one or more optical elements may be configured to direct the therapeutic radiation to a targeted area of an eye of a patient. A temperature of the targeted area may depend on a dosage of the therapeutic radiation. The detector system may be configured to measure thermal radiation emitted by the targeted area responsive to exposure to the therapeutic radiation. The one or more optical elements may be configured to optically couple the detector system to the targeted area.

Laser dosage determination by temperature monitoring

In some examples, a distributed acoustic detector system may include a frame structure and multiple acoustic detectors. The frame structure may be configured to be retained in a laser-based ophthalmo-logical surgical system aligned to an eye of a patient during therapeutic treatment of the eye of the patient with the laser-based ophthalmological surgical system. The acoustic detectors may be coupled to the frame structure and may be spaced apart from each other and electrically separated from each other.
