A spray pattern imaging apparatus, and method of operation, is described herein. The method is carried out by the spray pattern imaging apparatus that includes a frame having a set of known aspects corresponding to a first dimension and a second dimension within a first plane. The spray pattern imaging apparatus also includes a light source generating a planar light pattern within a substantially same plane as the first plane of the frame. The set of known aspects facilitate both correcting an image distortion and a scaling of a spray pattern image generated by an image acquisition device during a spray application by a nozzle positioned in a physical relationship with the planar light pattern such that spray particles emitted from the spray nozzle pass through the planar light pattern while an initial image is acquired by the image acquisition device.

Systems, devices, and methods for surgical illumination and imaging of ophthalmologic structures within a human eye are disclosed. In various embodiments, an emitter, imaging sensor, and a system control image processor are configured to irradiate ophthalmologic structures with near infrared light, detect near-infrared scatter from the irradiated ophthalmologic structures and visible light in real-time and generate or otherwise cause an image to be displayed on the user display that includes the detected near-infrared scatter from the irradiated ophthalmologic structures displayed in real-time. In one or more embodiments, the image is a virtual image of the irradiated ophthalmologic structures generated at least based on near-infrared light scattering coefficients of the irradiated ophthalmologic structures. In certain embodiments, the image displayed on the user display includes the detected near-infrared scatter from the irradiated ophthalmologic structures overlaid on a real-time view from a surgical microscope.

A cable detection system for detecting an end of a cable having a plurality of exposed different sections includes an illumination device and a camera. The illumination device emits an illuminating light to the end of the cable. The illumination device simultaneously emits a parallel light and a diffuse light to the end of the cable. The camera captures an image of the end of the cable. The parallel light sharpens a boundary between the different sections of the cable in the image, and the diffuse light clarifies a surface of the different sections in the image.

An illumination optical system includes a plurality of light sources arranged in an annular shape, and a prism plate that is formed in an annular shape about an optical axis of illumination light from the light sources. The prism plate includes a prism surface, upon which the illumination light falls incident and on which prism a plurality of prisms arranged in an annular shape along a circumferential direction of the prism plate, are formed, a flat section upon which the illumination light falls incident and which is formed in an annular shape along the circumferential direction of the prism plate, and an emission plane that emits the illumination light. The prism surface is formed on an outer peripheral side outward from a radius of the prism plate that is centered on the optical axis, and the flat section is formed on an inner peripheral side inward from the radius.
