Journal of Urology, 1985
Intraoperative profilometry measurements were done on 28 patients during various types of urethropexy to determine whether useful information could be provided to the operating surgeon. Successful Burch, Marshall-Marchetti and Stamey-Pereyra procedures resulted in a 50 per cent increase in urethral length.

Applied Optics, 1997
A new optical profilometry-linearly coded profilometry (LCP)-is presented. It uses a sawtoothlike linear light structure to code the surface to be measured and a phase-shifting technique to decode the profile. Two kinds of coding-light structure, one with right-angle triangle teeth and the other with isosceles triangle teeth, are proposed.

Optical heterodyne profilometry
Applied Optics, 1981A noncontact optical technique for the measurement of surface profile is described, which has a height sensitivity of the order of 1 A. It is based on a common path heterodyne interferometer in which two orthogonally polarized beams of slightly different frequency are focused on the surface to be measured.

Circular fringe projection profilometry
Optics Letters, 2016In this Letter, a novel three-dimensional (3D) measurement method, called the circular fringe projection profilometry (CFPP), is proposed. Similar to the conventional fringe projection profilometry, CFPP also requires fringe pattern projection and capture, phase demodulation, and phase unwrapping.

Aperture-coded confocal profilometry
Optics Letters, 2016This Letter introduces a novel principle to the confocal profilometry for simultaneous measurement of surface position and tilt. The principle relies on an angle-dependent coding of the illumination of the surface-under-test, achieved by dividing the pupil into several subapertures.

MICTURITIONAL URETHRAL PRESSURE PROFILOMETRY
Urologic Clinics of North America, 1996The technique of micturitional urethral pressure profilometry using a trilumen catheter provides a method of assessing the dynamic behavior of the lower urinary tract during voiding. This method of evaluation is simple to perform, highly reproducible, accurate, and clinically useful not only in diagnosing the presence of outlet obstruction, but also in

Improved Fourier-transform profilometry
Applied Optics, 2007An improved optical geometry of the projected-fringe profilometry technique, in which the exit pupil of the projecting lens and the entrance pupil of the imaging lens are neither at the same height above the reference plane nor coplanar, is discussed and used in Fourier-transform profilometry.

Urethral pressure profilometry
International Urogynecology Journal, 1991Urethral pressure profilometry has gained widespread usage in the diagnosis and clinical investigation of those patients with incontinence. This article aims to demonstrate the wider range of uses to which this technique has been applied and questions whether the underlying assumptions regarding its use are valid. Indeed is it a clinically useful tool?

SPIE Proceedings, 2001
With the increasing demand for micro-products and bioengineering research, resolutions of profiles with micrometer or even nanometer scale are becoming commonplace. In addition development of large integrated manufacturing systems and the real time life science growth and adaptation need high-speed display and real-time inspection.
