In some embodiments, the camera system comprises: an optical assembly to create an optical image from the optical wavefront; a deformable phase plate (DPP) to receive the optical image from the optical assembly and to adjust the optical image in accordance with a control signal, the DPP including a deformable surface suspended over a cavity filled with optical fluid, and electrical actuation elements configured to change a shape of the deformable surface based on the control signal, the electrical actuation elements arranged in a pattern in the cavity and, when activated, provide an electrostatic force on the deformable surface; an image sensor to convert the adjusted optical image into electrical signals; an image signal processor to generate a digital image from the electrical signals; and an estimator to estimate an aberration or tilt correction of the digital image and to generate the control signal based on the estimated aberration or tilt correction.

Miniaturized adaptive optics with deformable phase plate for digital tilt and aberration correction

The invention consists of a safety and arming device for a projectile and using micro electro-mechanical technology that incorporates at least three layers of substrate: a bottom, a top and at least one intermediate layer incorporating at least one mobile part with respect to the different layers of substrate wherein the bottom and top incorporate raised patterns, the raised patterns being evenly spaced over the bottom and the top such that the mobile part is always, when in movement, held immobile between the raised patterns of the bottom and those of the top, the raised patterns of the bottom being in contact with a lower face of the mobile part and the raised patterns of the top being in contact with an upper face of the mobile part.
