Their main function appears to be to detect light intensity changes from day to nighttime; resolving power of the female eye must be poor and e-vector discrimination would be absent. The eyes of the males consist of a smaller, dorsal region of ca. 500 om-matidia of about 250 μm length...
but because of the larger number of smaller facets of the male eye in combination with the structural differences of dioptric apparatus and retina (see above) the male eye would enjoy superior absolute visual sensitivity under dim conditions and a greater resolving power and ability to detect movem...
The microsystem consists of a planar compound eye optical system with coded sub-eyes and a planar image sensor, as shown in Fig.1(b). The light emitted or reflected by a close-range target (the angle of the target relative to the sub-eye is less than 1/10 of the sub-eye's FOV) ...
In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, as well as high temporal resolution in a tiny package. Compound eyes are ideally su...
just like the pattern of converging ommatidia in an insect eye. Because the microlenses create the waveguides, each microlens is perfectly aligned with its waveguide. The self-aligned self-writing process is crucial to the creation of the artificial compound eyes, because this process will also al...

Words have a great deal of power, so using the correct ones is important when discussing certain areas of science. In terms of molecules and compounds, there are some nuanced differences between the two, but for most purposes and conversations, the two can be used interchangeably. However, if...
We studied the scaling of wood ant compound eyes, exploring organ-level morphological changes in eye area, facet number and size and how this differed between nests. We found substantial heterogeneity in eye scaling between different nests within the same population. This heterogeneity calls into ...
However, the implementation of cameras directly mimicking the eyes of common arthropods is complicated by their curved geometry. Here, we describe a lensless planar architecture, where each pixel of a standard image-sensor array is coated with an ensemble of metallic plasmonic nanostructures that ...
