Electronic Distance Measuring Instruments

776
Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over...

    Summary
    This summary is machine-generated.

    We introduce a new, fast method to measure 3D light field display (LFD) performance using far-field analysis. Optimizing this far-field behavior enhances 3D image resolution and uniformity, proving it an effective tool for LFD assessment.
