Patent number: 11653834Abstract: Optical imaging or spectroscopy described can use laminar optical tomography (LOT), diffuse correlation spectroscopy (DCS), or the like. An incident beam is scanned across a target. An orthogonal or oblique optical response can be obtained, such as concurrently at different distances from the incident beam. The optical response from multiple incident wavelengths can be concurrently obtained by dispersing the response wavelengths in a direction orthogonal to the response distances from the incident beam. Temporal correlation can be measured, from which flow and other parameters can be computed. An optical conduit can enable endoscopic or laparoscopic imaging or spectroscopy of internal target locations. An articulating arm can communicate the light for performing the LOT, DCS, or the like. The imaging can find use for skin cancer diagnosis, such as distinguishing lentigo maligna (LM) from lentigo maligna melanoma (LMM).Type: GrantFiled: August 31, 2021Date of Patent: May 23, 2023Assignee: The Trustees of Columbia University in the City of New YorkInventors: Elizabeth Marjorie Clare Hillman, Sean A.

Patent number: 8619237Abstract: Laser-Scanning Intersecting Plane Tomography (L-SIPT) can provide a non-contact imaging geometry that can allow high speed volumetric scanning, such as of non-scattering to moderately scattering tissues. The L-SIPT imaging apparatus can include a first lens, located and configured to receive from a sample light received from different depths of the sample. A first light redirector can be located and configured to receive via the first lens and to redirect light received from the different depths of the sample to provide redirected light to a light detector capable of detecting individual measurements of light at different locations along a first direction.Type: GrantFiled: December 6, 2010Date of Patent: December 31, 2013Assignee: The Trustees of Columbia University in the City of New YorkInventors: Elizabeth Marjorie Clare Hillman, Matthew B.
