The KI will operate in a variety of Keck-Keck modes. Each mode becomes operational and open to the comunity after a commissioning period.
Visibility amplitude measurements are useful in determining the characteristic sizes and shapes of simple brightness morphologies. This was the first KI mode to become operational, and sensitivity information is available here. KI visibility mode operates in the near-infrared (H and K bands, ~ 1.3 - 2.4 microns).
Nulling is a high-contrast technique used to detect diffuse emission in the presence of a bright compact source. NASA's motivivation for sponsoring the nulling mode on KI is the detection and characterization of exo-zodiacal emission around nearby stars. KI nulling operates in the mid-infrared (N band, ~ 10 microns), the the nulling page for more information.
