Corneal imaging with slit‐scanning and Scheimpflug imaging techniques [PDF]
Australasian journal of optometry, The, 2011 Modern anterior segment imaging techniques, such as slit-scanning and Scheimpflug imaging, greatly improved the field of corneal imaging. Devices such as the Orbscan (Bausch & Lomb Surgical, Inc) and, more recently, the Pentacam (Oculus, Inc) and the Galilei (Ziemer Ophthalmic Systems AG) have brought a whole new range of clinical possibilities and ...

The use of infrared thermal imaging in tonometry with a Scheimpflug camera
Journal of Thermal Biology, 2021Infrared thermal imaging is currently used in almost every field of medicine. This paper presents the novel use of thermography in ophthalmology - using a thermal camera to assess correct intraocular pressure measurement depending on the position of the patient's head during non-contact tonometry.

Repeatability of lens densitometry using Scheimpflug imaging
Journal of Cataract and Refractive Surgery, 2014To evaluate the repeatability of different lens densitometry analysis modes performed with Scheimpflug imaging using the Pentacam HR device.University eye hospital, Frankfurt am Main, Germany.Cross-sectional study.Eyes were analyzed under mydriasis during 2 examinations performed by the same examiner. Three single measurements were taken to assess lens

Increasing the Spatial Resolution of BTF Measurement with Scheimpflug Imaging
Computer Graphics Forum, 2019AbstractWe present an improved way of acquiring spatially varying surface reflectance represented by a bidirectional texture function (BTF). Planar BTF samples are measured as images at several inclination angles which puts constraints on the minimum depth of field of cameras used in the measurement instrument. For standard perspective imaging, we show

Scheimpflug stereocamera for particle image velocimetry in liquid flows
Applied Optics, 1995A novel stereocamera has been developed based on the angular-displacement method, wherein the two camera axes are oriented in a nonorthogonal manner toward the object plane. The stereocamera satisfies the Scheimpflug condition such that the image plane, the object plane, and the lens plane are nominally colinear. A unique feature of the stereocamera is

Integrated line-field optical coherence tomography and scheimpflug imaging for corneal imaging [PDF]
Optics and Lasers in EngineeringPreviously we demonstrated a combined scanning-point optical coherence tomography (OCT) and Scheimpflug Imaging (SI) system, to provide cross-section images of the corneal layers and the whole anterior segment of the eye simultaneously. However, to fully

Unilateral electric cataract: Scheimpflug imaging and review of the literature
Journal of Cataract and Refractive Surgery, 2007A 22-year-old man presented with diminution of vision in the left eye 1 month after sustaining an injury from a high-voltage electric current to the left side of his head. Slitlamp examination and Scheimpflug imaging confirmed the typical anterior subcapsular lenticular opacities in the left eye and also documented early anterior subcapsular vacuoles ...

Performance evaluation of a Scheimpflug stereocamera for particle image velocimetry
Applied Optics, 1997We describe a novel stereocamera for particle image velocimetry (PIV) applications that incorporates the Scheimpflug condition that the object plane, lens plane, and image plane must be collinear. We examined the governing equations for this system using a computer-based sensitivity analysis to predict the accuracy of the in-plane and out-of-plane ...

Role of Scheimpflug Imaging in Traumatic Intralenticular Foreign Body
American Journal of Ophthalmology, 2006The role of Pentacam Scheimpflug imaging in evaluation of penetrating eye injury and intralenticular foreign body (ILFB).Interventional case report.A 35-year-old male presented to our clinical practice with penetrating eye injury and endophthalmitis. Scheimpflug imaging helped localize the intralenticular foreign body (ILFB). It confirmed the posterior
