Abstract: A two dimensional LIDAR scanning system uses a low sampling rate (250-500 MHz) analog to digital convertor (ADC) to sample an analog signal representing a reflection of a laser beam off of an object scanned by the LIDAR device. A splining method creates a representation of the analog signal using the sample points. The representation of the analog signal is used to detect a peak magnitude of the reflected laser beam and a time at which the peak magnitude occurred relative to the emission of the laser beam. A plurality of laser emitters and associated analog sensor outputs can be multiplexed into a single signal that is sequentially sampled by a single ADC with any sampling rate, at, e.g. 500 mega-samples per second. The plurality of samples of each analog signal are a representation of each analog signal generated from the plurality of samples using a splining method.

Abstract: A two dimensional (2D) LIDAR scanning system that uses a combination of a rotating polygonal mirror and a rotatable prism to scan an area of an object. The polygonal mirror and prism are rotated in combination to generate a scanning pattern. A pulsed laser is directed to the polygonal mirror and the prism is held in a fixed position. The polygonal mirror is then incremented a plurality of times to generate a scan line of LIDAR data. The prism is then incremented and a next scan line, e.g., up or down from the first scan line, is generated. An avalanche photodiode (APD) can read the reflections of objects for each scan point. Object reflections can be directed to the APD using either a polarizing beam splitter with a quarter wave plate, or a 50-50 beam splitter.

Abstract: A LIDAR scanning system uses a combination of a time-to-digital conversion (TDC) device and a multi-pixel photon counter (MPPC) to determine the peak location (time) and magnitude of a reflection of a laser beam off of an object. A configurable trigger threshold of the TDC indicates that a sufficient number of MPPC pixels have triggered that the peak detection module should begin sampling and storing MPPC counts of triggered pixels. When the light received from the reflected laser beam falls below the trigger threshold of the TDC, the MPPC stops sampling the MPPC counts. The peak magnitude of the reflection of the laser beam is determined from the highest sample count of the MPPC. A time at which the peak magnitude occurred is determined as the midpoint of TDC trigger points. The peak magnitude MPPC count is correlated to an intensity value.
