Latest Patents
One of Johnstone's latest patents is a microscopy system with auto-focus adjustment by low-coherence interferometry. This invention discloses several technical approaches that utilize low coherence interferometry techniques to create an autofocus apparatus for optical microscopy. These approaches enable automatic focusing on thin structures that are positioned closely to reflective surfaces and behind refractive materials, such as cover slips. The system allows for automated adjustment of the focus position into the sample region without disturbance from reflections off adjacent surfaces. Additionally, the measurement offset induced by the refraction of the material covering the sample is compensated for. The proposed techniques also include an instrument that allows the automatic interchange of imaging objectives in a low coherence interferometry autofocus system, which is particularly beneficial in combination with TDI (time delay integration) imaging, confocal, and two-photon fluorescence microscopy.
