NSSDCA ID: 1990-037B-06
Mission Name: HSTThe high-speed photometer (HSP) investigation makes fast-time-resolution (down to 10 microseconds) photometric observations of rapidly varying objects in the spectral range 1150 to 8700 A and linear polarimetric observations from 2100 to 7000 A of a wide variety of objects. It establishes an accurate link between observations made on existing visual and UV photometric systems and the corresponding observations of the objects observed by the HST Faint Object Camera. The instrument consists of four image dissectors: two sensitive in the UV and solar blind, the others sensitive in the visible and near infrared. A wide variety of bandpasses is formed by broadband and interference filters arranged in strips near the HST focus. Some of the filters are coated with a polarizing material. Apertures provide a choice of three fields of view: 0.4, 1.0, and 10.8 arc-s. The dissectors can be commanded to receive photoelectrons from any of the approximately 100 filter-aperture-polarizer combinations available.
