Abstract: This application describes Swept, Confocally-Aligned Planar Excitation (SCAPE) microscopy systems that incorporate a gradient index (GRIN) lens to relay images from their distal tip to their proximal tip so that 3D images of deep tissue can be captured, without undue loss of light. A zero working distance feature can be designed into the third objective to ensure that the light that exits the second objective in the SCAPE system is not lost. Alternatively, a tapered fiber bundle may be positioned between the second objective and the third objective in the SCAPE system to ensure that the light that exits the second objective is not lost. As yet another alternative, direct detection at the intermediate image plane without using a third objective can ensure that the light that exits the second objective in the SCAPE system is not lost.

Abstract: The present invention discloses a smart watch, including a housing with a mounting cavity, a top cover that covers the housing, a movement in the mounting cavity, a watch dial for displaying time, a light emitting module, a shake sensing module, a tap sensing module, and an audio player. The light emitting module is configured to be turned on when the shake sensing module senses that the smart watch is shaken and turned off when the tap sensing module senses that the smart watch is tapped. The audio player is configured to be started when the smart watch is tapped or shaken. According to the present invention, when needing to turn on the light emitting module, a user only needs to shake the smart watch worn on his/her wrist, and when needing to turn off the light emitting module, the user only needs to tap the smart watch with his/her hand. Compared with the way of turning on the light emitting module by pressing a physical button, the smart watch is simpler and more convenient in operation.

Abstract: A spacer for an immersion objective lens can be fabricated by pressing a set of sidewalls onto a mirror to form a liquid-tight cavity, filling the liquid-tight cavity with a first quantity of a UV-curable polymer, and curing the first quantity of the UV-curable polymer into a first solid mass that will be adhered to the mirror. The upper surface of the first solid mass is then positioned near the objective lens, with a second quantity of a UV curable polymer occupying the space between the first solid mass and the objective lens. Next, the position of the first solid mass is adjusted until it reaches a final position with respect to the objective lens. This adjustment may be assisted by checking the collimation of light reflected back through the mirror. The second quantity of the UV curable polymer is then cured.

Abstract: A microscope routes excitation light through a first set of optical components so the excitation light is projected into a sample and forms a sheet of excitation light at an oblique angle. The position of the sheet varies depending on an orientation of the scanning element. The first set of optical components routes detection light back to the scanning element, which routes the detection light into a second set of optical components. The second set of optical components forms an intermediate image plane that is imaged onto a detector. In some embodiments, a folding mirror is disposed between the first and second sets of optical components. In some embodiments, an optically transparent spacer covers the first objective and is configured to press against tissue being imaged. This spacer sets the working distance for the first objective to capture a particular range of depths within the tissue.

Abstract: The present invention is directed to a fiber optic device that enables multiphoton imaging with improved signal-to-noise ratio having a single piece of double-clad fiber (DCF). The device also includes all components for focusing, scanning and signal collection within an endomicroscope probe of 2.1 mm outer diameter (OD). The unprecedented imaging capability of this miniature endomicroscope is demonstrated herein via both ex vivo and in vivo experiments.

Abstract: The present invention is directed to an all-fiber-optic scanning endomicroscope capable of high-resolution second harmonic generation (SHG) imaging of biological tissues. The endomicroscope has an overall 2.0 mm diameter and consists of a single customized double-clad fiber, a compact rapid two-dimensional beam scanner, and a miniature compound objective lens for excitation beam delivery, scanning, focusing, and efficient SHG signal collection. Endomicroscopic SHG images of murine cervical tissue sections at different stages of normal pregnancy reveal progressive, quantifiable changes in cervical collagen morphology with resolution similar to that of bench-top SHG microscopy. A device according to an embodiment of the present invention can also be used to assess other pathologies, such as cancer. fibrosis, and inflammation. The present invention allows for diagnosis, monitoring of the effect of therapeutics, and surgical or interventional guidance.
