The HAWAII-4RG detector uses by default pixel clock of 100 kHz. While the fundamental readout mode remains the same, the detector offers a fast readout capability through subwindowing, where only a selected region of interest is read out. This reduces the total readout time and allows for higher frame rates. This is useful for applications requiring rapid frame updates in a small regions.
For example:
Subwindow of 15″ × 15″ (41 × 41 pixels)
Readout time: 18.25 ms* @ 100 kHz
* Experimental value at detector position (x,y) = (1,1); slightly different frame rates at different detector positions for the same subwindow size.
