Publication number: 20240068926Abstract: An aperture device for a flow cytometer is described. The aperture device includes a first aperture, and a second aperture spaced apart from the first aperture by a distance. The distance between the first and second apertures and a size of the first and second apertures are adjustable to create an optimal light intensity fringe pattern for analyzing a particle having a preselected type or characteristic at an interrogation zone of the flow cytometer.Type: ApplicationFiled: August 14, 2023Publication date: February 29, 2024Inventor: Ihor Berezhnyy

Publication number: 20210341380Abstract: Aspects of the present disclosure include flow cytometers configured to compensate for optical noise caused by operational change of a laser. Flow cytometers according to certain embodiments include a laser assessor configured to assess operational change of a laser. In embodiments, the laser assessor includes a reference detector and a mirror positioned between the reference detector and the flow cell that is configured to reflect forward scattered light to a forward scatter detector and allow non-scattered laser light to pass through to the reference detector. Methods for assessing laser functionality and, where desired, dynamically adjusting flow cytometer data, based on laser reference data from the laser assessor are also provided.Type: ApplicationFiled: April 26, 2021Publication date: November 4, 2021Inventors: Ihor Berezhnyy, Svitlana Berezhna

Patent number: 10327952Abstract: Systems are provided for delivering a calibrated ultraviolet radiation pulse at a treatment plane during a laser-ablation treatment of a patient's eye. Exemplary systems include an ultraviolet radiation source, and a fluorescent plate positioned to receive an initial ultraviolet radiation pulse produced by the ultraviolet radiation source. The fluorescent plate generates a visible light pulse in response to the initial ultraviolet radiation pulse.Type: GrantFiled: August 31, 2017Date of Patent: June 25, 2019Assignee: AMO Development, LLCInventors: Ihor Berezhnyy, Henry Price, Mark K.

Patent number: 10179070Abstract: Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.Type: GrantFiled: July 24, 2015Date of Patent: January 15, 2019Assignee: AMO Manufacturing USA, LLCInventors: Ihor Berezhnyy, Anatoly Fabrikant, Guangming Dai, Benjamin Logan, Anthony Tang, Henry Price, Stephen Calebotta

Publication number: 20180078418Abstract: A laser pulse energy control system which includes a laser source and a beam divider positioned to receive a calibration laser pulse produced by the laser source. The beam divider reflects a first portion of the calibration laser pulse along a first optical path toward a first plane and transmits a second portion of the calibration laser pulse along a second optical path toward a second plane. An energy meter determines an energy of the first portion of the calibration laser pulse at the first plane and a fluence profiler determines a fluence profile of the second portion of the calibration laser pulse at the second plane. The processor controls an energy of an ablation laser pulse produced by the laser source based on the fluence profile of the second portion of the calibration laser pulse and the energy of the first portion of the calibration laser pulse.Type: ApplicationFiled: September 15, 2017Publication date: March 22, 2018Applicant: AMO Development, LLCInventors: Ihor BEREZHNYY, Mark K.

Patent number: 9702692Abstract: Embodiments generally describe systems, devices, and methods for focusing and calibrating beam profilers. A test object is provided that may include an internal housing rotatable within an external housing. The internal housing may house a light source, a collimator, a filter, and/or a diffuser. A plate may be mounted to the internal housing and may include a plurality of markings. In some embodiments, to focus a beam profiler, the test object may be positioned adjacent the converter plate of a beam profiler. Marker images may be captured and a focus quality may be assessed therefrom. A position of the converter, objective, and/or camera of the beam profiler may be adjusted based on the focus quality. To calibrate, images of the markings in several rotational positions may be captured and used for calibration. The markings may be rotated to several positions by rotating the internal housing relative to the external housing.Type: GrantFiled: December 19, 2016Date of Patent: July 11, 2017Assignee: AMO Manufacturing USA, LLCInventors: Ihor Berezhnyy, Anthony Tang, Henry Price
