Title:
TIME-OF-FLIGHT INDEPENDENT OF OBJECT REFLECTIVITY
Document Type and Number:
Japanese Patent JP2021056223
Kind Code:
A
Abstract:
To provide an improved system and method for determining the time-of-flight.SOLUTION: A method comprises: illuminating 114 an object with a first illumination pulse at a first illumination power level; illuminating 116 the object with a second illumination pulse at a second illumination power level different from the first illumination power level; integrating 118 at least a portion of a first return pulse which is the first illumination pulse returning from the object to determine a first return time; integrating 120 at least a portion of a second return pulse which is the second illumination pulse returning from the object to determine a second return time; and determining 122 the distance to the object independently of reflectivity of the object by using the first and second return times.SELECTED DRAWING: Figure 2
