Принадлежит: Sanyo Electric Co Ltd

Laser light emitted from a laser light source is converted into light having a dot pattern by a projection optical system for projection onto a target area. The projection optical system is configured such that the density of dots in a peripheral portion of the dot pattern is smaller than that in a center portion of the dot pattern in the target area. A dot pattern captured by irradiating a dot pattern onto a reference plane is divided into segment areas. A distance to each segment area is acquired by matching between dots in each segment area, and a dot pattern acquired by capturing an image of the target area at the time of distance measurement.

A device and method for LADAR ranging using relatively long laser pulse widths and slower system clock speeds is provided. The center points of the sent and received laser signal such as Gaussian laser pulses are identified by time sampling the sent and received laser signal waveforms at predetermined time positions. The signal energy within each time sample of the respective sent and received laser signals defines a clock “bin”. The received laser signal generates an output from a photodetector cell on a focal plane array that is converted into voltage. The signal energy is integrated using a capacitor array for each of the clock bins and is representative of the signal energy in each time sample. The output of the capacitor array is collected in buffer and digitized. Signal processing means extracts the center of the transmitted and received pulses and the time-of-flight calculated as the time between the transmitted and returned centers of the laser signal pulses.
