Yes - HiRISE does TDI - (128 lines I think)
Essentially as eash row 'dwells' on the target, it adds the photons, then passes the count onto the next row of the 128 rows....thus increasing SNR by, in theory, 128 times. Of course there is noise and some losses within the process - but that's the theory as I understand it. MOC NA, MOC WA, HRSC and CTX are, as I understand it, single line Pushbrooms. HiRISE a Pushbroom-with-TDI, and MARCI / THEMIS a Pushframe design. Discreet framing cameras were on board the Vikings, Mariners, and the crap SRC channel on HRSC  Doug |
