In most cases, the eyepiece field diaphragm opening diameter determines the view field size. The field size in the specimen plane is then defined as the field number divided by the magnification of the objective: If an auxiliary lens is inserted between the objective and eyepiece, the magnificati...
Figure 2: Field of view decreases as magnification increases, limiting the area you can image at higher magnifications. Matching Camera and Microscope FOV One thing to keep in mind is that a microscope FOV is circular, and a camera FOV is square/rectangular, as seen in Fig.3 Top. Pairing...
Camera is used to view the back of the retina. (D) Resulting image of the checkerboard object on the Zemax-simulated eye retina, view from the back of the retina. (E) Image of computer monitor checkerboard object on the retina of an extracted mouse eye, as viewed with the camera. (F...
Our data show that within V1, V2, and V3, map surface area and cortical magnification as a function of eccentricity are similar between adults and children. We also find that both adults and children have greater V1 surface area representing the horizontal than vertical meridian of the visual...
This logarithmic mapping summarizes the observed curve of cortical magnification and the linear scaling of receptive field size with eccentricity. Also under the influence of such a mapping size changes on the retinal field correspond to shifts across the cortical surface [2], i.e. the mapping is...
Currently, the use of optical sectioning to expand DOF still has the problem of inconstant magnification. Here, we develop an extended the depth of field (EDOF) and zoom microscope, which can realize EDOF with constant magnification and high resolution. Besides, the proposed microscope can ...
of view, a Canon APS-C crop sensor camera has at least 1.6xMOREdepth of field that a 35mm full frame camera would have - when the focus distance is significantly less then the hyperfocal distance (but the 35mm format needs a lens with 1.6x the focal length to give the same view). ...
Indeed, the great numerical apertures accessible, through computational light-field imaging, means that the factor preventing focusing closer and closer to the object focal plane will be the then greater and greater magnification of the objects leading to the observation of diffraction limited features,...
