IDL Image

The image from the infrared camera can be read directly from the control PC using the IDLPC routines that connect directly to the TCP/IP socket. a IDL procedure similar to the following:


;procedure to take an image with the ir camera on fast 
;it really should be made more general by reading the ccd_status command
pro image,a
;reply=call_external('idlfast.so','debug',255)
reply=call_external('idlfast.so','xmit','ccd_status seq=Frame',/S_VALUE)
;print,reply
reply=call_external('idlfast.so','xmit','ccd time=1 nbytes=131072 ',/S_VALUE)
print,reply
a=fltarr(256,256)
b=call_external('idlfast.so','array',a,size(a))
tvscl,a
end

The procedure does the following:

opens the socket on the node containing the camera (fast)
sets the desired sequencer (Frame)
makes the exposure (1sec) and then asks for the data (131072 bytes) to be sent back
copies the returned data into an IDL array (a)
