摘要： A solid-state radiation detector includes a pattern of conductive metal on a zinc oxide substrate. The pattern provides an arrangement of interdigitated electrode fingers. The wide band gap substrate is sensitive to UV light, which can cause a conductivity change in the substrate. The electrode fingers are configured to sense a difference in substrate conductivity resulting from UV light. The detector has a fast response time, which enables it to detect Cherenkov light. The compact detector provides savings on size, weight, and required power. Thus, the solid-state detector can be used to replace photomultiplier tubes in Cherenkov detectors. The features of the novel detector allow for an improved system to detect and monitor UV radiation, especially during deep space missions.

摘要： In exemplary implementations of this invention, a camera can capture multiple millions of frames per second, such that each frame is 2D image, rather than a streak. A light source in the camera emits ultrashort pulses of light to illuminate a scene. Scattered light from the scene returns to the camera. This incoming light strikes a photocathode, which emits electrons, which are detected by a set of phosphor blocks, which emit light, which is detected by a light sensor. Voltage is applied to plates to create an electric field that deflects the electrons. The voltage varies in a temporal “stepladder” pattern, deflecting the electrons by different amounts, such that the electrons hit different phosphor blocks at different times during the sequence. Each phosphor block (together with the light sensor) captures a separate frame in the sequence. A mask may be used to increase resolution.

摘要： A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.
