Optic low-pass filterNyquist criterionAliasingSampling of photoelectric imaging system could infinitely replicate the scene spectrum in spectrum space.If the sampling intervals were too large to satisfy the Nyquist criterion,the replicas would be overlapped and there was aliasing.The optical transfer ...

It is shown that a frequency modulated optical transmitter at 1.5 m in conjunction with a standard singlemode fibre can have highpass transfer characteristics. Equalising this frequency response, the characteristics of the receiver lowpass filter can be determined that are required for the method of...

A Negative Group Delay (NGD) prototype filter design based on the reciprocal transfer function of a low-pass Butterworth filter of a given order, is presented. The out-of-band gain of the prototype transfer function is capped at a finite constant value via multiplication by a transfer function...
