4D hyperspectral surface topography measurement system based on the Scheimpflug principle and hyperspectral imaging.

Applied Optics, 2023
A four-dimensional (4D) hyperspectral surface topography measurement (HSTM) system that can acquire uniform inelastic signals [three-dimensional (3D) spatial data] and reflection/fluorescence spectra of an object is proposed.

Extension of Scheimpflug principle in multi-line laser scanning measurement

International Symposium on Precision Mechanical Measurements, 2021
Scheimpflug principle is a description of the geometric relationship between the orientation of the plane of sharp focus, the lens plane, and the image plane of an optical system, when the three planes intersect along a common line, which is widely ...

Full-field flow measurement in evaporating sessile droplets based on the Scheimpflug principle

Applied Physics Letters, 2019
The direct visualization of flow fields plays an important role in droplet evaporation. However, the refraction of light at the curved droplet surface makes it challenging to obtain the accurate flow field.

Three-dimensional Scheimpflug principle and its application to full-focus positioning.

Journal of The Optical Society of America A-optics Image Science and Vision
The Scheimpflug principle specifies the relationship between the object, lens, and image planes, providing conditions for focusing the entire image plane even for tilted objects.

Aerosol detection experiment of Lidar system based on Scheimpflug imaging principle

Applied Optics and Photonics China
Atmospheric lidar is one of the important tools for environmental monitoring. However, the conventional backscattering lidar has a blind detection zone, which limits the effective monitoring of aerosol concentrations near the ground. A lidar system based
