| Research Abstract |
We have performed our 7 micron deep survey program made with Infrared Space Observatory (ISO) , the infrared camera of ISO (ISOCAM).
We have found 15 sources above a 5 sigma_<rms> significance in a small selected area (3'x3') in the lockman HI hole. Among the 15 sources 14 objects have also been observed in the near infrared (NIR : -2 micron) . The majority of the 7 micron sources have NIR counterparts most of which are considered to be galaxies with intermediate redshifts.It is, however, infriguing that a few 7 micron sources have no NIR counterparts. There objects may be heavily reddened populations which have not been detected by existing optical and NIR deep surveys.
