Biopolymers are a prominent class of functional materials ideal for high-value applications, and they fascinate researchers and experts from various fields. Polymers are flexible building blocks in many chemical combinations and blend to create composite materials with complementary qualities. The biomedical use of polymeric biomaterials was analyzed scientifically and technologically in this study, along with a compilation of their uses, manufacture, mechanical qualities, and key characteristics for the biomedical sector. The volume of scholarly publications and patents demonstrates the current knowledge of polymeric biomaterials. These biomaterials may now supplement, strengthen, or perform a particular role in the human body. Immune reactions persist due to the complexity of biological systems, impeding the growth of tissues and functioning organs in a laboratory setting.

In this work, non-linear optical properties of a Sony SVGA liquid crystal spatial light modulator sample are estimated by utilizing a single beam Z-scan technique with He-Ne laser at 632.8 nm. It was found that the magnitude of non-linear refractive index (NLR) is (0.694×10 -7 cm 2 /mW) with a positive signal, demonstrates a self-focusing phenomenon, while the magnitude of non-linear absorption (NLA) for this sample is (0.0101×10 -1 cm/mW), the pure magnitude of the NLR is (0.138×10 -5 cm 2 /mW). These results are compared with past investigations in various liquid crystals types. The obtained results showed that the sample have a high ability of originating optical limiters, switches, and modulation gadgets.

In this work, a contemporary optical system is designed using a technology of spatial light modulator (SLM). This system is depending on the ability of altering light beam into different optical patterns according to a signal feedback injected computationally to the SLM. The effects of control parameters on the SLM operation are studied such us brightness (B) which determines the constant DC voltage applied to SLM pixels, and contrast (C) determines the maximum AC voltage amount that can be applied to the SLM. The influences of the transmission linearity of image intensity are controlled by the gamma adjustment which can be used to align non linearity of image intensity. The grey scale is used to control and imagine which signals corresponding to grey levels and image location. The resolution and orientation of the obtained images are altered by the screen format to make optical experiments more satisfied, hence different ratios of amplitude and phase modulation can be understood.
