Fiberscope, Probe, Camera
Tuesday, September 05, 2006
The Fiberscope Camera mount was designed and developed for providing the interface to the Fiberscope eyepiece. A mechanical linkage in the Fiberscope eyepiece automatically changes the lens system of the ocular from a virtual image to a real image, for the camera film (or digital camera). When the Camera is properly attached, it automatically overrides the ocular diopter setting and focuses the eyepiece for recording.
Camera attachment: A beam splitter prism mounted in the Camera, diverts part of the light beam passing into the Camera. The light beam reaches a light-sensitive transducer (photocell), which electronically measures the image brightness. The electronic signal enables the light source to automatically produce a flash duration required for correct exposure.
Teaching aid attachment: An optical teaching aid attachment can be coupled to the eyepiece, allowing for a second observer to view the image. A prism beam splitter diverts light to a secondary Fiber Optic bundle. The bundle carries the image to a secondary ocular for observation by a second person. A recording camera could be attached to the main ocular if a record is required without affecting the secondary viewing. A switch on the teaching aid attachment allows activation for momentary diversion of 100 percent of the main ocular during the record mode.
Illumination system: An incoherent fiber optic bundle can be used to transmit light through the Fiberscope to the tip. Special lens systems on both ends of the Fiber Optic bundle are required to maximize the light beam energy. Wide-angle illumination is provided at the functional end of the Fiber Optic bundle.
Optical Fibers: Thirty-micron Fiber Optic is used as a compromise between large Fiber Optic for maximum packing density and the required flexibility. High heat levels produced by high-intensity light sources require the use of dichroic coating and heat-absorbing filters. Heat sinks and forced air-cooling may also be required to prevent overheating.
