摘要： Extracting data in pulsed light, the method includes receiving input light at an image intensifier tube. At a power supply coupled to the image intensifier tube, current to the image intensifier tube is varied to implement automatic brightness control of the intensifier tube based on intensity of the input light received at the image intensifier tube. At a signal processor coupled to the power supply, changes in voltage or current supplied by the power supply occurring as a result of changes in the intensity of the input light to the image intensifier tube are detected. Based on the changes in voltage or current supplied by the power supply, data embedded in the input light to the image intensifier tube is extracted.

摘要： Methods and systems for performing 3-D LIDAR measurements of objects simultaneously illuminated by two or more beams of light in the far field are described herein. A 3-D LIDAR based measurement device simultaneously emits at least two beams of light into a three dimensional environment from different locations. A portion of the three dimensional environment is simultaneously illuminated by the two or more light beams at a distance of at least five meters from the LIDAR device. However, the two or more light beams do not overlap at a distance less than five meters from the LIDAR device. The beams of light are slightly divergent, having highest intensity at the device and steadily lower intensity further away. By overlapping illumination beams in the far field, but not near the LIDAR device, overall intensity is maintained at moderate levels throughout the field of view of the LIDAR device.

摘要： An imaging device (10) includes: a controller (3) which generates a light emission signal and an exposure signal; a light source unit (1) which receives the light emission signal and emits light; a light receiver (2) which obtains the exposure amount of reflected light at a timing in accordance with the exposure signal; and a calculator (4) which outputs a distance signal (distance image) by calculation on the basis of the amount of signals included in imaging signals received from the light receiver (2). The controller (3) generates two or more patterns of varying phase relationships between the light emission signal and the exposure signal, and outputs the light emission signal and the exposure signal in a cycle that is different between at least two of the patterns.

摘要： An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There is a variable probability of a photon detection on the receiver, and a controller (370, 380, 390; 365, 470, 475, 380, 390; 570, 580, 590, 390) controls the photon detection probability of the receiver, based on a light level. By controlling the detection probability according to a light level, the receiver can have an increased dynamic range, and without the expense of using optical components. This can apply even while detecting very weak signals since the receiver can still be in a photon counting mode while the detection probability is controlled. The light level can be indicated by an output of the receiver itself, or by another detector external to the receiver.
