Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

479
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

12.8K
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

    Area of Science:

    • Optical Metrology
    • 3D Measurement Technologies

    Background:

    • Fringe projection profilometry (FPP) is a key high-accuracy 3D measurement technique.
    • Binary defocusing methods enhance FPP speed but limit measurement depth to isolated regions.
    • Existing optimizations primarily extend the front of these limited depth ranges.

    Purpose of the Study:

    • To develop a novel strategy for expanding the measurement depth range in FPP.
    • To overcome the limitations of isolated depth ranges in traditional binary defocusing systems.
    • To achieve a super-large and continuous measurement depth range.

    Main Methods:

    • Proposed a dual-focal optimization strategy using a cylindrical lens group.
    • Simultaneously adjusted projector focal lengths in meridian and sagittal planes.
    • Optimized focal lengths based on light field distribution properties to expand the proper defocusing region.

    Main Results:

    • Successfully created a larger, continuous proper defocusing region.
    • Increased the measurement depth range from two isolated ranges (120 mm and 650 mm) to a single range of 950 mm.
    • Acquired improved measurement results over the expanded depth range.

    Conclusions:

    • The dual-focal optimization strategy effectively overcomes the depth limitations of traditional FPP binary defocusing methods.
    • This approach enables a super-large and continuous measurement depth range.
    • The method offers enhanced performance for high-accuracy 3D measurements across a wider range.
