摘要： 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).

摘要翻译： 所描述的光学成像或光谱可以使用层状光学断层摄影（LOT），漫射相关光谱（DCS）等。 一个入射光束在目标上扫描。 可以获得正交或倾斜的光学响应，例如在与入射光束不同的距离处同时进行。 可以通过将响应波长分散在与入射光束的响应距离正交的方向上来同时获得来自多个入射波长的光学响应。 可以测量时间相关性，从中可以计算流量和其他参数。 光学导管可以实现内窥镜或腹腔镜成像或内部目标位置的光谱。 铰接臂可以通信用于执行LOT，DCS等的光。 成像可以用于皮肤癌诊断，例如区分恶性黑色素瘤（LMM）的恶性疟原虫（LM）。
