the actual distance from the centre o f the lens to the illuminated object, U is 20.0 cm.Calculate the focal length f, o f the lens using the equation ...](b)The student
In a method for determining focal length of a lens mounted to a camera a distorted image of a scene is captured. A distortion-correction function is applied on the distorted image or on a portion of the distorted image. A most representative distortion-correction function is identified and by...
lidar sensor, determines distance between a motor vehicle (1) and objects (4, 5) in a surrounding area of the motor vehicle. A spatial distance between two points on the objects is determined via intercept theorems from measured object gap, focal length of lens of the camera and image ...
Images were captured on a confocal microscope (Leica TCS SP5 II, Leica Microsystems) connected to an upright microscope, using an oil-immersion plan Apo 60x A/1.40 NA objective lens. Image acquisition was performed with LAS (Leica Microsystems Gmbh, Wetzlar, Gemany) and further processed with ...
For the pre-operative calculation of the power of an intraocular lens, three input parameters are needed: the axial length of the eye (AL), the refractive power of the cornea, and the distance between the front of the cornea and the back focal plane of the intraocular lens, the so-called...
Kinesin-14 microtubule-based motors have an N-terminal tail attaching the catalytic core to its load and usually move towards microtubule minus ends, whilst most other kinesins have a C-terminal tail and move towards plus ends. Loss of conserved sequence
Microscopy for PTBP1, 53BP1 and beta-Tubulin detection was performed using IX71 Olympus microscope using a 40X objective lens or 60X oil-immersion objective as indicated. Mean fluorescence of nuclear PTBP1 signal was analysed for a minimum of 300 cells per sample in two independent experiments ...
(e.g., number of bits of intensity data per pixel), focal length of lenses, depth of field, etc. In general, for a particular application, any cameras capable of focusing on objects within a spatial volume of interest can be used. For instance, to capture motion of the hand of an ...
The capabilities of cameras 102, 104 are not critical to the technology disclosed, and the cameras can vary as to frame rate, image resolution (e.g., pixels per image), color or intensity resolution (e.g., number of bits of intensity data per pixel), focal length of lenses, depth of...
However, it is noted that, in preferred embodiments of the present invention, dither modulation is preferably achieved either by controlling the focal length of lens 72 in a mechanical fashion or in an electro mechanical fashion or by changing the focal position of lens 72 with respect to ...
