The Miro 110 and Miro 310 are both based on a 1
Megapixel (Mpx) custom-designed CMOS sensor.
The maxiumum resolution is 1200 x 800, with a 20
micron (µm) pixel size and with 12-bit pixel depth.
The Miro 110 and 310 cameras are rated at ISO
11,100T (mono) and 1800T (color).
The Miro 120 and 320S are both based on a >2 Mpx,
custom designed CMOS sensor. The maximum
resolution is 1920 x 1200, with a 10 µm pixel size,
and 12-bit pixel depth. The Miro 120 and 320S are
both rated at ISO 8900T (mono) and 1100T (color).
Both the Miro 110 and Miro 120 cameras provide a
1.6 Gigapixel/second (Gpx/s) throughput while the
Miro 310 and Miro 320S double that for 3.2 Gpx/s
throughput.
These throughputs translate to the Miro 110
yielding over 1600 frames-per-second (fps), the
Miro 310 over 3200 fps, 720 fps for the Miro 120 and
1380 fps for the Miro 320S, all at full resolutions.
Maximum frame rates at reduced resolution are
400,000 fps for the Miro 110, 650,000 for the Miro
310, 250,000 fps for the Miro 120, and 325,000 for
the Miro 320S monochrome.
Depending on the model, the minimum exposure
time is either 1 µs or 2 µs for sharp, blur-free
images using a global electronic shutter.
Vision Research’s unique Extreme Dynamic Range
(EDR) feature is standard on all models. With
EDR enabled, each pixel in a frame will receive
one of two exposure times – a short exposure
for potentially overexposed pixels and a longer
exposure for pixels receiving normal light levels.
