Null Hartmann and Ronchi-Hartmann tests
Applied Optics, 1990Assuming the Ronchi and the Hartmann tests to be null tests, we were able to design special screens for each test that produce aligned straight fringes and a square array for the observed patterns. It also became clear that the screen filter and observing planes for both tests can be interchanged.

AbstractSince 1921, when Henry Hartmann first described his procedure for rectal carcinoma, multiple modifications of the original technique have been proposed. However, the basic principle of a rectal pouch has always been retained. Two cases of carcinoma developing in such a pouch are described; both occurred years after creation of the pouch.

Shack–Hartmann versus reverse Hartmann wavefront sensors: experimental results
Optics Letters, 2020With respect to the classical Shack–Hartmann (SH) wavefront sensor (WFS), the recently proposed reverse Hartmann (RH) sensor inverts the locations of the filtering and observation planes and forms a direct image of the pupil on a detector array. The slopes of the wavefront error (WFE) are then reconstructed by using a double Fourier transform algorithm.

To assess the complications and results of Hartmann's procedure and secondary restoration of continuity for left-sided colonic disease.Retrospective study.University hospitals, Northern Ireland.72 Patients who required a Hartmann's procedure over a 13 year period (1985-1998).Of these 45 (63%) were done as emergencies and 27 (38%) as elective procedures.

Hartmann's operation for rectal cancer is a term that has been misapplied. Complications have occurred when the rectal stump has been too long and the blood supply has been insufficient for clean healing. That is not what Hartmann described. His procedure was to transect the rectum and to close it at, or below, the peritoneal reflection, which is where

Henri Hartmann and the Hartmann Operation
Archives of Surgery, 1980Reference to the "Hartmann operation" for diverticulitis of the sigmoid colon is found with increasing frequency in the current medical literature. In principle, this operation consists of the removal of a segment of colon containing an acutely inflamed area of diverticulitis, with or without perforation or fistula.

Modal integration of Hartmann and Shack–Hartmann patterns
Journal of the Optical Society of America A, 2014Instead of measuring the wavefront deformations directly, Hartmann and Shack-Hartmann tests measure the wavefront slopes, which are equivalent to the ray transverse aberrations. Numerous different integration methods have been described in the literature to obtain the wavefront deformations from these measurements.

Zonal processing of Hartmann or Shack–Hartmann patterns
Applied Optics, 2017Instead of measuring the wavefront deformations, Hartmann and Shack-Hartmann tests, we measure the wavefront slopes, which are equivalent to the ray transverse aberrations. Numerous different integration methods have been described in the literature to obtain the wavefront deformations from these measurements.
