As with the SA4 and SA1.1, the FASTCAM SA5 motion analysis camera utilizes a 20µm square CMOS sensor to obtain an ISO light sensitivity of 10,000 for the 12-bit monochrome version of the camera, and 4,000 for the 36-bit color, both measured to the published ISO 12232 Ssat standard. The square aspect ratio is extremely useful when used on a microscope, borescope or other round optics, where the full resolution can be enjoyed, versus rectangular aspect ratios where the wider horizontal resolution has to be reduced to accommodate the round optics.
The FASTCAM SA5, SA4 and SA1.1 all connect easily to your laptop through the Gigabit Ethernet port, provide both dual composite video and HD-SDI BNC outputs and can be operated using the optional LCD keypad. Cameras are provided with both the threaded C-mount and Nikon F/G mount that enables newer Nikon lenses without the manual iris/aperture ring to be used. An optional Canon EF else mount permits control of the lenses aperture and focus through our Photron FASTCAM Viewer (PFV) camera control / image sequence editing software.
In addition to our bespoke file formats (RAW, RAWW and MRAW), PFV enables users to directly save recorded image sequences in a wide variety of industry video and image formats, including:
- START MODE – Recording commenced after the trigger signal is received.
- ENTER TRIGGER – The available memory is split evenly around the trigger signal (T0).
- END TRIGGER – The camera continuously records until the trigger is sent, whereupon data before that point is saved.
- MANUAL MODE – The user decides how much time is saved before and after the trigger.
- RANDOM MODE – The user decides how many frames are saved every time a trigger is applied.
- RANDOM RESET – As above, but the camera’s timing is reset to begin at the trigger point.
- RANDOM CENTER – An equal number of user specified frames are saved for every trigger application.
- RANDOM MANUAL – The user determines how many frames are saved, both before and after the trigger.
- RECORD ON COMMAND – The camera keeps recording for as long as the trigger switch is closed or the TTL signal applied.
- RANDOM LOOP – Way too complicated to explain here!
- DUAL SPEED – The recording speed cane be changed, up or down, by a factor of up to 8, each time a trigger is applied.
Memory can also be partitioned into a maximum of sixty-four partitions to enable many short duration slow motion recordings to be captured sequentially. Data saved in one memory partition can be downloaded while another partition is still recording. To further increase record capability, the camera’s bit-depth can be decreased from 12-bit to 8-bits to increase the record duration by fifty percent.
A clearly labeled I/O (Input and Output) cable breaks out into multiple BNC connector ‘pig-tails’ to facilitate easy connection to external peripherals and make precise camera synchronization (including to IRIG/GPS satellite time codes and similar) and triggering as easy as possible.
