Abstract
The development and investigations of large-formate (8-inch) real-time photothermoplastic (PTP) camera are carried out. The PTP camera is applied for operative recording of 3D- images by means of compound and digital holography and visualization of these holograms as 3D-static images. The optimization of the recording regimes is fulfilled with use the model of the relief-phase PTP images thermodevelopment, proposed by authors. According with that model, the achievement of maximal value of deformation (diffraction efficiency) is based on the opportunity in increasing of charge contrast of electrostatic latent image formed early by the moment of the viscosity decreasing during the thermodevelopment process. It is achieved by means of the control of the thermodevelopment regime. Also, the opportunities of the increase of the camera size (to 14 inch), of the rising of photosensitivity value and the enlarging of its spectral range, of the creation of Benton holograms and of the increasing of the speed of response to 25 Hz are discussed.
