I called binogramme the pairs from bioptical compositions.

In fig. 3 the binogramme is vertical.
In fig. 4 the binogramme is horizontal. 

The horizontal binogramme is used in publications and, in some cases, as appendix to the vertical bioptical painting, for naked eye contemplation.



Bioptical Device


In the studies I performed so as to multiply the means in communications by fine arts, I considered the fact that the receptor subject should be as little influenced as possible by the optical intermediation elements so as to introduce in painting and sculpture the stimuli of: binocular rivalry, colour fusion and stereoscopy.

With respect thereto, influences in perception may be obtained by drifting away from object. For example, it is a well-known fact that observing the satellites of Jupiter through the astronomic telescope causes more powerful psychic influences than in case they are broadcasted by television.
I developed an optical device that fulfils the following features:
- Deviation from the convergence of the eye axes within the limits of medical prescriptions 
- The optical system simplified at maximum, respectively, two plane mirrors positioned only in front of one eye, with modifications below 1% of the visible spectrum 
- Low weight (~ 30 grams at the handmade model; weight could be substantially decreased in case of industrial production)
- Adaptable on various supports (for headset with and without using eyeglasses, for handle, for a support similar to the eyeglasses frame, to be adapted on eyeglasses).

 The bioptical device is attached to the headset by means of a connecting link that enables a fast an easy movement in the three positions presented in the photos.

- Moving the device from one eye to the other causes essential modifications in the visual perception by reversing the components of the  stereo-binogram corresponding to the eyes, obtaining: space reversing of the linear and chromatic perspectives, modifications in the binocular rivalry effects, as well as modifications of tones and shades in the color fusion

- Integrating the composition in the environment, because the eye that remains free perceives also the adjacent field (120 degrees)

- The possibility to accomplish the bioptical fresco.
