Abstract

As a remote sensing instrument, pushbroom hyperspectral imager demonstrates its advantages in many application operations. It brings people better spectral resolution with high signal-to-noise-ratio. As increase of the demand of environment study and city planning. In 1997 Pushbroom Hyperspectral Imager (PHI) was built in Shanghai. It has a refractive optical system with reflective grading as spectral divergence device and area array silicon CCD as detector. It upgrades SAIS with optimized optical system, 12 bit digitizer and PENTIUM in-bed computer. Special efforts are mae on parallel data recording to save more information with an inexpensive hardware configuration. The system can be easily mounted on gyro stabilize platform and work with dynamic GPS. PHI has succeeded in remote sensing operation for city planning of Beihai, Guangxi province. This paper will introduce the development of PHI, including system design, calibration and performance in operation. Plans for further studies, including real-time data process for pixel binning and data bus improvement for data rate speeding, are also introduced.
