High angular resolution instrumentation is revolutionizing modern astronomy by enabling detailed studies of celestial phenomena with unprecedented clarity. This capability is crucial for exploring exoplanetary atmospheres, star-forming regions, and the environments surrounding supermassive black holes in galactic nuclei. By leveraging techniques such as adaptive optics and interferometry, astronomers can overcome atmospheric turbulence and achieve resolutions well beyond conventional limits. A cost-effective and resilient laser-guided single-conjugate adaptive optics system presents an opportunity for significant enhancement of a large number of existing 1–4 meter telescopes. This presentation highlights recent technological and scientific advancements enabled by four state-of-the-art systems: iRobo-AO; SALTO, an advanced laser-guided adaptive optics platform for medium-class telescopes; SCExAO VAMPIRE, a high-contrast imaging instrument incorporating machine learning-based non-common path aberration correction at the Subaru Telescope; and BIFROST, a high-spectral-dispersion beam combiner within the Asgard Suite at the Very Large Telescope Interferometer (VLTI). These instruments exemplify the forefront of high-resolution observational astronomy and provide critical tools for the next generation of astrophysical exploration.
