A method of forming a crystallographically oriented silicon layer over a glassy layer of, for example, SiO.sub.2. A templating layer of a layered perovskite, preferably Bi.sub.4 Ti.sub.3 O.sub.12, is deposited on the glassy layer under conditions favoring its crystallographic growth with its long c-axis perpendicular to the film. The silicon is then grown over the templating layer under conditions usually favoring monocrystalline growth. Thereby, it grows crystallographically aligned with the underlaying templating layer.

A spectral dosimeter for detecting both the fluence and the energy spectrum or ionization density spectrum of high energy radiation comprising multiple MOS capacitors on a single semiconducting integrated circuit chip which collect ionization charge generated by high energy particles passing in the vicinity of the individual capacitors. The capacitors are individually read by comparison with reference capacitors. The capacitors are fabricated or operated such that varying amounts of collected charge will cause the capacitors to be read as having collected a threshold amount of charge.

Spectral dosimeter

A polarimetric image recorder which records only the net polarization of the viewed scene. An optical lens system projects the light originating from the viewed scene onto a thin layer of an alkali halide crystal containing anisotropic color centers. Polarized light reorients the color centers and creates a net polarization in the layer. The net polarization of the layer is read by such means as shining polarized light through the layer and then through a polarizer set perpendicularly to the polarization of the light source. Whatever light is viewed through the reader represents a net polarization in the scene.
