  • Patent number: 10646105
    Abstract: The present invention is directed to an achromatic endoscope which employs a diffractive microlens. Along with a broadband rotary joint and a custom 800 nm SD-OCT system, ultrahigh-resolution 3D volumetric imaging over a large area becomes possible. The diffractive microlens can be used directly with a GRIN lens, making the endoscope design simpler and cost effective. Preliminary ex vivo 3D intraluminal imaging was performed with the endoscope in conjunction with a home-built broadband rotary joint and a spectral-domain OCT system, demonstrating the performance of the diffractive endoscope. Considering the miniature OCT imaging probe is the required component for using the OCT technology in internal organs, the proposed approach will have a broad impact on endoscopic OCT imaging by improving OCT resolution in any applications that involve a miniature OCT probe, as intravascular OCT imaging, gastrointestinal (GI) tract imaging, airway imaging etc.

  • Publication number: 20200025566
    Abstract: Systems and methods for sensing angular motion using a microelectromechanical system (MEMS) gyroscope are described. These systems and methods may be useful for sensing angular motion in the presence of low-frequency noise, which may be noise below 1 KHz. In a system for sensing angular motion, low-frequency noise may give rise to duty cycle jitter, which may affect the demodulation of the sense signal and cause errors in angular motion estimates. The systems and methods described herein address this problem by relying on double-edge phase detection technique that involves sensing when the rising and falling edges of the resonator signal deviate from their expected values in the idealized 50% duty cycle scenario. To prevent the formation of ripples in the double-edge phase detection that may otherwise affect the demodulation of the sense signal, a switch may be used. The switch may be maintained in a non-conductive state when a ripple is received.
