A high-resolution image sensor is used to determine the focal point for each pixel by detecting focal changes (i.e. the degree of blur in an image). To detect focal changes, multiple images of the target are captured while the lens moves in the Z direction. For in-focus images, the ...
Surface Pro 7 Addresses the issue affecting the camera's performance caused by insufficient memory or storage capacity and enhances the overall security posture of the devices, protecting customers from potential threats. View Surface Pro 11
All Surface Pro 8 models support Windows Hello Face Authentication (also known as Face ID), which allows you to sign in to your account faster, easier, and more secure with your face. It also has an improved Windows Hello Infrared (IR) camera that can recognize and log you in ...
The other camera is a color scan camera and has a two-dimensional detector chip upstream to a dispersive element. An independent claim is also included for a method for detecting total surface area of a wafer.VOLLRATH WOLFGANGBUETTNER ALEXANDER...
the rust layer can contaminate the detection instruments and reduce the accuracy of defect detection. In non-contact detection methods, traditional non-destructive testing equipment is not adept at detecting complex surfaces, while vision-based detection leveraging image analysis holds distinct advantages....
Surface wetting is a multiscale phenomenon where properties at the macroscale are determined by features at much smaller length scales, such as nanoscale surface topographies. Traditionally, the wetting of surfaces is quantified by the macroscopic contac
etc. A three degree of freedom motion mechanism is used to control the movement of laser fringe. When combined with stereo microscope and camera, it can not only generate microscopic fringe pattern, but also obtain fringe image sequence. Based on this system, a 3D surface shape reconstruction ...
Interestingly, the enhanced fluorescence can also be readily imaged by naked eye through a filter, and recorded as photographs taken by a digital camera. On the left-hand side of Fig. 5b the border between a AgFoN region and flat Ag film is shown as a reflected white light image. When ...
a Schematic (not-to-scale) showing a droplet attached by capillarity to an elastic cantilever with spring constant k. The friction force acting on the droplet can be measured by moving the substrate and detecting the cantilever deflection Δx with a camera, since F = kΔx. b Photograph of...
Particleboard surface defect detection technology is of great significance to the automation of particleboard detection, but the current detection technology has disadvantages such as low accuracy and poor real-time performance. Therefore, this paper pro
