Query: Increasing Linear Dynamic Range of Commercial Digital Photocamera Used
  in Imaging Systems with Optical Coding   Methods of increasing linear optical dynamic range of commercial photocamera
for optical-digital imaging systems are described. Use of such methods allows
to use commercial photocameras for optical measurements. Experimental results
are reported.
