Schmidt camera Schmidt camera A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930. Some notable examples are the Samuel Oschin telescope (formerly Palomar Schmidt), the UK Schmidt Telescope and the ESO Schmidt; these provided the major source of all-sky photographic imaging from 1950 until 2000, when electronic detectors took over. A recent example is the Kepler spacecraft exoplanet finder. Other related designs are the Wright Camera and Lurie–Houghton telescope. The Schmidt camera was invented by German-Estonian optician
Helmut Schmidt (parapsychologist) was appointed Research Director of the Institute in 1969. Schmidt's early psychokinesis experiments involved machines with one red and one green light. Subjects would attempt to make one light illuminate more than another. Schmidt has reported success rates of 1–2% above what would be expected at random over a large number of trials. Critics have written Schmidt's experiments in parapsychology have not been replicated. Schmidt worked alone with no one checking his experiments. He was accused of being a careless experimenter. The psychologist C. E. M. Hansel found flaws in all of Schmidt's experiments into clairvoyance, precognition and psychokinesis. Hansel
