A laser line filter is a precision optical filter with an extremely narrow passband centered on a standard laser wavelength. These optical filters are used to prevent the distortion of measurement ...

Delta Optical Thin Film has lifted the application range of variable filters to new levels by introducing a new powerful type of linear variable filter (LVF). Since Delta Optical Thin Film offered the ...

The field of applications and instrumentation that utilize laser sources is quickly advancing. For example, confocal and multiphoton microscopy, Raman spectroscopy, and flow cytometry all make use of ...

The pace of the world of digital communications is increasing at a tremendous rate. Daily, the engineer is requested to compact more data in the same channel bandwidth with closer channel spacing. As ...

Most embedded engineers writing firmware have used some sort of digital filters to clean up data coming from various inputs such as ADCs, sensors with digital outputs, other processors, etc. Many ...

It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better than a strictly linear one. 1 The Kalman filter is a ...
