OCT was first introduced in 1991[Huang, 1991] and has since been adapted to a number of clinical biomedical imaging settings including ophthalmology. Its largest ophthalmology impact has been the imaging of the retina.

In OCT, the anatomic layers within the retina can be visualized and the thickness of the retina can be measured. This is an exceptional advancement in diagnostic imaging because it allows real-time visualization of the microstructure of a tissue without the need to excise and process a biopsy specimen. It is used both for diagnosis and to guide intervention.

notchfilter是什么

Optical coherence tomography (OCT) is noninvasive, noncontact, imaging technique that can make images of structures in the retina with a resolution of 10 to 17 microns. Cross-sectional images of the retina in a fashion similar to ultrasound but at a much higher resolution and using light waves rather than sound waves.

The OCT is useful in visualizing the pathology of many eye diseases including diabetic retinopathy, macular degeneration, macular holes, epiretinal membranes, macular edema, central serous choroidopathy and optic disc pits.

Anatech Electronics RF BandStop filters also referend to as RF Notch Filters expertise is derived from the many years of design experience, knowledge, and emphasis on customer requirements.  The RF Notch Filter is used to reject just a single frequency within a certain bandwidth.  The bandstop filter or RF Notch Filter requires more Q than any other type of RF Filter in order to have an equivalent steepness as oppose for example a band pass filter.  Since most RF filters are derived from the basic low pass filter, and then converted thru mathematical processes to a band stop filter, that type of filter requires more sections in order to have an equivalent pass band to reject band transition.  That said the RF Notch Filters are more complex to design, and requires careful adjustment, and attention to the exactness of the element values in order to give good results.
