摘要： Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.

摘要： A multispectral synchronized imaging system is provided. A multispectral light source of the system includes: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further includes a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

摘要： Imaging systems and methods involving a videoscope including cameras; a filter feature in optical communication with the cameras, the filter feature configured to independently filter or tandemly filter light from each camera; an independently adjustable aperture in optical communication with the filter feature, the independently adjustable aperture configured to limit transmission of filtered light; independently adjustable zoom features in optical communication with the independently adjustable aperture, the independently adjustable zoom features including corresponding independently adjustable zoom channels, and each independently adjustable zoom feature configured to independently zoom independently limited filtered light; a prism in optical communication with the independently adjustable zoom channels, the prism configured to redirect independently zoomed, independently limited, filtered light; and a shared focus feature in optical communication with the prism, the shared focus feature comprising a shared focus channel, and the shared focus feature configured to focus redirected, independently zoomed, independently limited, filtered light.
