Abstract: A dosimetry system may comprise a film stack and a laser system for applying a laser beam to the film stack. The system may further comprise an interferometry system configured to acquire from the film stack a first interferometric dataset comprising a first composite signal and a subsequent interferometric dataset comprising a subsequent composite signal. The system may also include a processor for comparing the first and subsequent composite signals, wherein a difference between the first and subsequent composite signals indicates a change in the film stack thickness. A dosimetry method may comprise applying a laser beam to such a film stack, acquiring the first and subsequent interferometric datasets, comparing them to detect a change in the film stack thickness, and ceasing to apply the laser beam to the film stack if the change in the film stack thickness exceeds a predetermined threshold.

Abstract: Technologies are described for detection of eye surface vibrations to determine cell damage within a treatment area of an eye undergoing laser treatment. Eye surface vibrations may be caused by intraocular pressure waves that form during the laser treatment. For example, the pressure waves may originate from a plurality of bubbles forming and/or rupturing inside cells located in the treatment area. The bubbles may form as energy from a treatment laser beam is absorbed by the retinal tissue. The pressure waves may be measured at the surface of the eye through Doppler vibrometry to determine if the cells within the treatment area have been damaged. The damage to the cells may include cell lysis, a rupture of cell membranes, scarring, and/or photocoagulation, among other examples.

Abstract: Technologies are described image a treatment area during laser treatment using a time-gated image capture device and an electronic display. During laser treatment, a physician may monitor a treatment area to ensure efficacy and to prevent over-treatment. Light reflected from the area that includes treatment area may be detected by an image capture component and converted to a signal. An image processor may then generate image data based on the signal and provide the image data to be displayed on an electronic device. A gating component may send instructions to the image capture component and/or the image processor to prevent inclusion of light from one or more laser pulses generated during treatment. Excluding light from the laser pulses may prevent glare in captured images allow a monitoring physician to safely and accurately monitor the treatment area.

Abstract: Technologies are generally described for providing inductively removable assembly bonding. Inductive elements may be placed strategically at bonding locations between two or more coupled components. At disassembly time, the elements may be heated through Radio Frequency (RF) energy causing the bonds to break and components to separate. For example, inductive elements placed near plastic stake bonds between dissimilar materials in an electronic device may be employed to separate the dissimilar materials during a recycling process. According to some examples, the elements may also be heated through a directly applied electric current via a network of connections designed into the assembly.
