Abstract

Disclosed is a camera which can be built based on arrays of cantilever calorimeters. The camera is color sensitive; its spectrum ranging from UV to infrared. Bimetalic cantilevers can be used as micromechanical calorimeters (1). Such calorimeters can be coated with dye-layers to make them sensitive to irradiation, for example, to light.

Cantilever-Based Camera

      Disclosed is a camera which can be built based on arrays of
cantilever calorimeters.  The camera is color sensitive; its spectrum
ranging from UV to infrared.  Bimetalic cantilevers can be used as
micromechanical calorimeters (1).  Such calorimeters can be coated
with dye-layers to make them sensitive to irradiation, for example,
to light.

      As demonstrated in recent work on dye-superconductor light
sensors (2), the dye layer can be chosen such that a sensor is
sensitive to a particular part of the spectrum only.  Therefore, it
is possible to use two-dimensional arrays of dye-coated cantilever
calorimeters as color-sensitive cameras.

      It is noted that in contrast to semiconductor cameras, of which
the spectral response is limited by the bandgap of the semiconductor,
this camera is sensitive to a much wider spectrum of electromagnetic
irradiation, including the infrared.
