| holographic microscopy | <technique> A mode of light microscopy in which a highly coherent, laser beam is split into a reference and main beam, with the reference beam (usually travelling outside of the microscope) being made to interfere with the main beam that has passed through the specimen. The interference of the two mutually coherent beams forms a hologram. The depth of field gained by viewing the hologram is essentially infinitely great, and the contrast mode or observation can be switched to dark field, phase contrast, interference contrast, etc., after the hologram has been formed by the microscope in bright field.

| holometabolous metamorphosis | Insect development from egg, through successive larval instars, pupa, and adult; the latter is distinct from the first two forms of the insect, permitting specialization of feeding (larval) and reproductive-flying functions (adult); characteristic of the higher insect orders, such as Coleoptera (beetles), Hymenoptera (bees, wasps, ants), Diptera (two-winged flies), and Siphonaptera (fleas).
