Camera adapter based optical imaging apparatus

摘要

The invention describes several embodiments of an adapter which can make use of the devices in any commercially available digital cameras to transform the digital camera into a fundus camera for inspecting the back of the eye, or into a microscope. The camera adapter is adapted to be placed between the camera device and the object. The devices in the camera being used are at least its optical source, photodetector sensor, memory, shutter and autofocus. Means in the adapter are provided to employ these devices and allow camera to operate its autofocus capability and its different color sensors. Methods of investigation of an object are also presented of using the adapter to transform the camera into an imaging instrument, where the effect of adjustments of elements inside the adapter are guided by the displaying screen of the camera.

主权项

1. A camera adapter, for transforming a camera device having a housing containing a camera into an imaging instrument of an object, where the camera in the camera device has at least an optical illumination source creating excitation light, a photodetector array sensor behind an entry, a shutter release and a memory,
wherein the camera adapter is adapted to be placed between the camera device and the object and comprises: a housing removable frame having securing fittings to hold the camera device 10 securely in place, which housing removable frame comprises: a first light output to transfer light to the object, a second light output placed on the adapter in front of the commercial camera housing device for directing light from the adapter onto the photodetector array, at least a light input for accepting excitation light from the at least an optical illumination source of the commercial camera housing device, means for directing the excitation light from the at least one light input towards the first light output, where the means for directing excitation light employ at least an element out of the group of deflecting mirrors and beamsplitters, an object interface for directing light from the object into the second light output, so that the camera device is employed to collect an image of the object via the adapter into the memory of the camera device.
