Unformatted text preview: BME 6500: What is the cut-off frequency (-3 dB ) for this imaging system (Note that the system works as a low pass filter)? 1.2) A one-dimensional spatial sampling array (line sensor) has a element spacing of 40 x m = . Find the spatial Nyquist frequency associated with the array. What is the maximum spatial frequency that we can capture with this imaging system? 1.3) Describe what is the packing fraction of a fiber optics bundle? What is its relationship with quality in imaging capture? 1.4) Find the CFT of the 1-D object ( ) ( ) sin / ( ) / DC A x F x I I x = + , f(x) >0 a) Sketch & dimension f(x) vs x. b) Sketch & dimension F(u) vs u. c) What is the recommended sampling frequency of an imaging system to recover all the features of this object?...
