\section{Introduction}

This is the third paper in the serie of publications presenting the results of speckle interferometric observations of binary stars 
performed with telescopes of the Observatorio Astron\'omico Nacional (OAN) of the Instituto de Astronom\'ia Universidad Nacional 
Aut\'onoma de M\'exico. Regular speckle interferometric measurements of binary stars have been made with telescopes of the OAN since 
2008 (Orlov et al. 2009).  This paper presents the results of double star observations carried out with the 1.5~m and the 2.1~m 
Telescopes of Sierra San Pedro M\'artir National Astronomical Observatory (OAN-SPM) in August and November of 2010. For these observations 
we developed a new detector. This detector is a combination of the CCD camera Watec 120N with a third generation image intensifier. 
The third generation image intensifier also allows us to carry out near infrared speckle interferometric observations. The results 
reported here consist of 238 measures of 225 pairs with a primary limiting magnitude of $V=12.2$; 211 of them have separations of 
less than $1\arcsec$. In these speckle observations we confirmed and measured 38 binaries first detected by Hipparcos. The paper 
concludes with a tabulation of the observational results. The analysis of specklegram has been performed using  the technique described 
by Tokovinin, Mason, \& Hartkopf (2010). 

\section{Brief Description of the Equipment}

The observations were performed with the CCD camera Wat-120N which is optically connected with the 18~mm third-generation image intensifier. 
Because the Watec CCD device Wat-120N is primarily designed for amateur astronomers, its limiting sensitivity (0.00002~lx) is not 
enough for speckle interferometry, so we had to use the third-generation image intensifier. We describe some technical details related 
to our CCD camera. The Wat-120N is an interline CCD camera where each single frame is a combination of two half-frames. One half-frame 
contains odd lines while the second one consists of the even lines. One half-frame is taken every 1/50th of a second. As one can see in 
Figure~1, in the case of good seeing conditions there are no difference between odd and even half frames. So, we can make the data 
processing for a complete frame $720 \times 480$. If the seeing conditions are not so good (Figure~2), the half-frames are very different. 
In this case we have to perform the data processing for the odd and even half-frames separately. Also we have to note that the Wat-120N 
does not have square pixels; this has to be taken into account during data processing.

The other disadvantage of Wat-120N is a manual control. We developed a simple Ethernet controller to resolve this problem. The set 
of our camera controls consists of three parts: gain control, gamma control, and on/off image intensifier switcher. 
The gain control has 8 values from 0 to 7 (Figure~3, the value 7 corresponds to the maximum gain). The gamma control allows three 
modes: linear (Off), low (Lo) and high (Hi). Two modes Lo and Hi are not linear and, if one needs measure accurate magnitude differences 
of components, they are not used during data recording. The last control is a switch on/off for the image intensifier.

\section{Observations and Results}

Data were recorded during the two observation campaigns carried out in August and November 2010. In August observations of 105 stars 
were performed at the OAN-SPM 1.5~m telescope. The atmospheric conditions (seeing and transparency) were excellent. For three nights 
in November 2010 we observed 120 stars with the 2.1~m telescope of OAN-SPM under poor atmospheric conditions. All the measurements 
were made through the R filter with a 640/130 nm bandpass window. In these speckle observations we measured 38 new binaries detected by 
Hipparcos (ESA 1997). For each star, a typical observing procedure involved the accumulation of one set of 998 frames (1996 half-frames). 
One frame consists of a two-dimensional $440 \times 400$ array of 8-bit numbers. After the calibration we determined that the pixel 
scales are equal to $0.039\arcsec$/px and $0.038\arcsec$/px for the 2.1~m telescope and for the 1.5~m telescope, respectively. Tables~1 
and 2 contain the results of the measurements of binary stars performed at the 1.5~m and 2.1~m telescopes. The format for the  
presentation of these measurements is the same as in our previous publication (Orlov et al. 2010). The first column contains the 
epoch-2000 coordinates in the format used in the Washington Double Star (WDS) Catalog (Worley \& Douglass 1997). The second column 
gives the name of the star or the discoverer designation. The third column gives the epoch of the observation in fractional Besselian 
years. The two following columns contain the measured position angles given in degrees and the angular distances in arcseconds. The last 
three columns show ephemerides calculated for the date of observation and references to publications in which orbital elements can be 
found (Hartkopf \& Mason 2003). 

\section{Conclusion}

We have presented the results of binary star observations focused on binaries from the WDS catalogue. In particular, we have been interested 
in new binaries discovered by Hipparcos. We confirmed 38 new binaries detected by Hipparcos. The main aim of this study was in the 
selection of binaries with a fast relative motion allowing to obtain candidates for determinations of new orbits. From our observation 
results we can also conclude that our new detector based on Wat-120N CCD is suitable for speckle observations with the OAN-based telescopes.
