摘要： An integrated LIDAR receiver includes a single detection element to provide both imaging and ranging functions. The single detection element includes an opaque photocathode, a microchannel plate (MCP) electron multiplier, and a phosphor coated anode covered with a metalized layer. The metalized layer on the phosphor anode allows electrons striking the anode to be detected as a prompt electrical current and used as a first output signal to provide ranging information. Visible light (photons) is also output from the anode in response to electrons striking the phosphor in the anode, and is used to provide an intensified image of a scene. The visible light may thereafter be detected by an imaging sensor, such as a CCD camera. The phosphor anode is biased at ground potential. A transimpedance amplifier is coupled to the metalized layer on the phosphor anode and, with the anode being at ground potential, operates with a virtual null input.

摘要： An integrated LIDAR receiver includes a single detection element to provide both imaging and ranging functions. The single detection element includes an opaque photocathode, a microchannel plate (MCP) electron multiplier, and a phosphor coated anode covered with a metalized layer. The metalized layer on the phosphor anode allows electrons striking the anode to be detected as a prompt electrical current. The prompt electrical current is detected through a transformer that couples the anode to a power supply. The power supply biases the anode relative to the MCP and photocathode such that the MCP is grounded. The use of a transformer allows the prompt anode current to be detected without having to ground the anode, thereby simplifying the power supply circuitry. The detection of the prompt electrical current provides a first output signal useful for ranging information. Visible light (photons) is also output from the anode in response to electrons striking the phosphor in the anode, and is used to provide an intensified image of a scene. The visible light may thereafter be detected by an imaging sensor, such as a CCD camera.
