Abstract: A high-dynamic-range hybrid solid-state lidar system, which is based on a transponder array module, includes a transmitting system, a transceiver integrated optical system, a one-dimensional scanning device, a detecting system, and an information processing system. An information processing control circuit and a gain control module increase a total amplification factor, in a single timing period, of a gain circuit over time, thereby alleviating an echo signal intensity distortion, and expanding a dynamic ranging range. The system uses the one-dimensional scanning device and the transceiver integrated optical system composed of a circulator, a lens set, and an optical fiber array, so that the optical system is separated from an avalanche photo diode (APD) detector, and focusing is not required. A temperature of a linear APD array is monitored in the detecting system to adjust a reverse bias voltage of an APD correspondingly and alleviate unstable gain caused by a temperature change.

Abstract: Disclosed are an omnidirectional ghost imaging method and an omnidirectional ghost imaging system based on the mechanism of bio-inspired retina-like. According to the application, the logarithmic polar mapping characteristic of the bio-inspired retina-like structure is utilized to generate an annular pattern sequence of the bio-inspired retina-like, and the pattern sequence is utilized to modulate a light source. After being reflected by the target around the curved mirror, the light is projected onto the curved mirror and diffusely reflected. According to the reversible characteristics of the optical path, the light after diffuse reflection is reflected to the original light source by the half mirror and half lens, and the reflected light intensity with target information is received by the bucket detector. The reflected light intensity measurement value with target information is correlated with the annular pattern sequence of bio-inspired retina-like used for modulating the light source.
