Latest Patents
John D Knight's latest patents include innovations in diffraction grating position sensing and control for scanning monochromators. One of his notable inventions is a double-pass scanning monochromator designed for use in optical spectrum analyzers. This device features an input optical fiber that emits an input light beam, which is then diffracted by a diffraction grating to produce a spatially dispersed light beam. The system includes a slit for selecting a portion of the dispersed light beam, a motor for rotating the diffraction grating, and a shaft angle encoder for sensing the grating position. The light that passes through the slit is directed back to the diffraction grating, which recombines it to produce an output light beam. A polarization rotation device is incorporated to ensure that the output is independent of the input light beam's polarization. Additionally, a micropositioning assembly translates the output optical fiber to automatically track the output light beam and provide optical chopping.
