    • apodes An order of fishes to which very different limits have been assigned. In the classification of Linnæus (1758), a group of osseous fishes without ventral fins and comprising a heterogeneous assemblage of representatives of various modern orders. In Bloch and Schneider's system (1801), some one of several orders of fishes, the name being repeated under several so-called classes which were distinguished by the number of fins. As thus used, the word was a descriptive rather than a distinctive term. In Cuvier's system, a section of the malacopterygians, the name being applied adjectively to such forms as are destitute of ventral flns. The true eels, symbranchiate eels, Gymnonoti, typical Ophidioidea and Ammodytoidea were referred to this group. By various later writers the name was used as a distinctive ordinal name. By T. Muller the Ophidioidea and Ammodytoidea were eliminated. By Gill, in 1861, the order was restricted to the typical and symbranchiate eels, and later (1884) to the true eels, or teleost fishes with the intermaxillaries atrophied or lost, the supermaxillaries lateral, and the body anguilliform and destitute of ventral fins. These characters are correlated with various others which justify the isolation. The principal families are the Anguillidæ, Ophichthyidæ, and Murænidæ.
    • apodes In De Blainville's system of classification, a division of his Entomozoaria; the apodal, as distinguished from the chætopod, entomozoans. It includes the leeches, and is approximately equivalent to the Hirudinea of modern naturalists, but contains many intestinal worms.

Usage

In literature:

I tell you all this because I don't want to pose as a kind of apodal angel of mercy.
"The Red Planet" by William J. Locke
Apodal: with single, simple tubercles instead of feet, in larvae; without feet = apodous.
"Explanation of Terms Used in Entomology" by John. B. Smith
Though the larvae of bees are apodal, they are not condemned to absolute immobility in their cells; for they can move by a spiral motion.
"New observations on the natural history of bees" by Francis Huber
EEL, the popular name of fishes belonging to the teleostean sub-order Apodes.

In science:

Based on the EBL tool resolution, our mask should be capable of producing manufacturing-error-limited contrasts of 1.5×10−6 without the use of an apodized Lyot stop; with our choice of experimental setup and wavelength, achieving a deeper contrast of 10−8 at the peak would require 20 nm precision.
Using Notch-Filter Masks for High Contrast Imaging of Extrasolar Planets
To get rid of this effect it is quite common to apodize the image (see Schlegel et al. (1998) for example) but this destroies the information on the edge of the image.
IRIS: A new generation of IRAS maps
If we find bright exozodiacal clouds around all of our target stars, we will need a design without such apodization.
Coronographic Methods for the Detection of Terrestrial Planets
The implicit physical assumptions and limited numerical accuracy of methods used to design these masks can yield sub-optimal designs. The masks under consideration generally employ binary phase variation, continuous amplitude apodization, or binary amplitude apodization.

We obtained noncoronagraphic pupil images with the apodizer in the beam with the 3 filters and radial azimu thally averaged profiles were plo tted against radius (Figure 6).

In other words, the scattering function of a linear isoplanatic optical instrument can be made by apodization as close as one wishes to a delta-function on any fixed finite subdomain of the image plane.
Does negative refraction make a perfect lens?
It is proved in that it is possible to increase the resolution ability (in the Rayleigh’s sense) of a linear isoplanatic optical system without a limit by apodization even in the presence of noisy background in the image plane.
Does negative refraction make a perfect lens?
The Fresnel arrays in our prototype only have 116 Fresnel zones, are not apodized, and the zero order mask is wide compared to the resolution of the field optics.
Fresnel Interferometric Imager: ground-based prototype
With a higher number of Fresnel zones and an adapted zero order mask, numerical simulations with a non apodized square aperture and 700 Fresnel zones show that a 10−7 dynamic range is obtained over nearly the entire field, except the four thin spikes, at a five resolution elements radius from the center of the PSF peak.
