Area of Expertise

Infrared technology, Infrared spaceborne remote sensing


Dr. Marija Strojnik Scholl (a fellow of the OSA and the SPIE) earned a BS degree in Physics, MS degrees in Physics, Optical Sciences, and Engineering (Engineering Executive Program at UCLA, '81), and Ph. D. Degree in Optical Sciences. Her appointments include Engineering manager at Boeing Corp., staff scientist at Honeywell Technology Center, Senior Optical Scientist at Caltech's Jet Propulsion Laboratory, and professor. She developed a novel method for autonomous star-based navigation, successfully used in Cassini mission to outer planets. The SPIE bestowed on her the prestigious George W. Goddard award in 1996. Dr. Scholl was editor for Applied Optics, Infrared, for two terms, and she continues to sit on the editorial boards of Infrared Physics and Technology and "Giorgio Ronchi" Foundation. Marija's service to the SPIE includes having chaired over 25 conferences on Infrared Technology and Infrared Spaceborne Remote Sensing. She was a Guest editor of two issues of Optical Engineering.

Lecture Title(s)

Optical Detection of a Planet Next to a Bright Star
Possibility of existence of planets in solar systems outside our own hold a special fascination for humans. After flying by, dropping probes, and even landing devices on most planets within our own solar system, the search for an extra-solar planet is included in every proposal to either build a larger and better earth-, space-, or moon-based telescope, or observatory facility. The preliminary analysis seems to indicate that wavelength band from 25 µm to 50 µm is most promising in solving this problem. A number of IR technological challenges are to be overcome before the actual detection system can even be considered in a detailed design. The significant technical challenges of finding a planet will be described, including a number of concepts currently under considerations. Then details are given on the feasibility of detecting a planet with an instrument concept designed specifically for this purpose, a space-based, rotating rotationally shearing interferometer.

Human and Machine Vision
Of all the senses that a human employs to receive the information from its environment to allow him/her to maintain him-/herself alive, avoid danger, and even control his/her environment, vision is by far the most important. We will review the salient features of human visual system and discuss the instruments as an extension of the vision process. This includes infrared and its delayed shadows, and information in other spectral regions, and also such traditional instruments as telescopes and microscopes, and simple intelligent cameras that are expected to keep a robotic vehicle clear of danger. Spatial exploration with cameras and rovers will be featured.
