As an example, here is a set of monochromatic images of the planetary nebula IC351, extracted from the datacube of a test snap shot which was taken for us at the russian 6m telescope with a micropupil spectrograph in November 1996.
The images show the emission in [O III] 5007, H beta, He II 4686, two Argon lines, and in the continuum which shows up as the central star (of magnitude 14). The brightness distributions agree remarkably well with what is know from direct interference filter images, in particular regarding the shape of O3 and Hbeta, demonstrating the usefulness of a single exposure with respect to extinction and calibration.
You may take this example as fulfilling the request of George Jacoby and his co-authors at NOAO in a paper of some 10 years ago, -
however, not exactly with the number of resolution elements they want
("thousands of input apertures"):
these are just smoothed images of an 8 by 16 elements lens array.
