SIM uses sophisticated optical systems to generate pre-determined excitation light patterns, and reconstruction algorithms to enhance the resolution by up to a factor of two. The optical set-up of SIM relies on delicate free-space optics to generate the light patterns, and a high numerical aperture objective lens to project the pattern on the sample. These arrangements are prone to miss-alignment, often with high costs, and with the final resolution-enhancement being limited by the numerical ap","authors_text":"Balpreet S. Ahluwalia, Firehun T.
