Systems and methods for illumination and imaging of targets

Abstract

An imaging device may include: a first illumination opening for outputting first light having a first illumination distribution at an object to illuminate the object; a second illumination opening for outputting at the object a first light having a second illumination distribution Distributed second light to illuminate the target, the second lighting distribution at the target is substantially similar to the first lighting distribution, the second lighting opening is spaced apart from the first lighting opening, the first and second lighting distributions are simultaneously Provided to and overlapped at the target. The illumination from the first and second openings can be matched to the same aspect ratio and field coverage as the imaged field of view.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Application Serial No. 62 / 255,024, filed November 13, 2015, entitled "SYSTEMS AND METHODS FORILLUMINATION AND FMAGING OF A TARGET," which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to the fields of illumination and imaging. More specifically, the present disclosure relates to illumination and imaging of target materials. Background technique [0004] Illumination is an important component of imaging systems such as eg broadband imaging systems with self-contained illumination. In many applications of imaging systems, such as in medical imaging, it can be a challenge to achieve uniform full-field illumination of the imaging field of view and also provide sufficient illumination intensity to produce a sufficiently strong imaging signal. Observing matching the illumination profile to the imaging field...

AI Technical Summary

Problems solved by technology

Conventional illumination projections in imaging systems can feature anamorphic projections that match the imaging field of view, but typically only feature a single illumination opening and are not configured for adjacent working distances

Single aperture lighting systems can lead to large shadowed areas that obscure vision when illuminating complex features such as, for example, human anatomy or other biological material

Existing designs for live surgical imaging and lighting equipment can utilize multiple illumination openings to minimize shadowed areas such as ring lights surrounding imaging optics, but these designs waste excess illumination outside the field of view and fail to Uniform illumination of the field of view within a certain working distance range
