It is because the green laser beam light of laser pointer

Resulting in dispersion, density and low efficiency. The heat distribution system is to put hot spots in the sub-scanning direction is divided into eight, eight put hot grayscale images from low density to high density of a pixel, the results of the image is continuous and smooth. Put hot in the heat distribution system, 8 each can control 256 grayscale, 8 put hot combination with its gray-scale ability to control up to 11-bit (256 x 8 = 2024), this method also known as l0-bit density decomposition performance. It also uses high image quality correction technology, the resistance correction, uniformity correction, heat ratio correction and clarity to make corrections. Resistance correction to correct the error of heat resistance itself. It is also the source power for laser pointer to develop fast.It is because the green laser beam light of laser pointer is much brighter
Uneven uniformity correction for the resistance correction, the use of optical readers were to make corrections; heat ratio correction is mainly used for the circuit voltage drop supplementary correction; sharpness correction is to achieve the best imaging results gray scale image for further processing. Application of all these technologies to ensure the stability and accuracy of the image quality, to meet the need for diagnostic imaging. Dry laser camera film from top to bottom is divided into five layers: a protective layer; sensible heat layer; piece grass-roots level; UV absorption layer; matt layer of photosensitive material is an emulsion contains micro-capsules and the chromogenic reagent material by adhesive spread support in the film body. Some summary should be recorded for laser pointer .
Through the thermal head heating, micro-capsules permeability, reagent into the capsule and then back into the non-permeability and stop the hair color reaction, the above took place after the formation of visible images. Form an image of the color reagent was isolated by micro-capsule, making the photo imaging after long-term preservation of this thermal reaction and micro-capsule technology known as micro-isolation technology. In order to obtain stable, high-quality images using a grayscale adjustment, shade adjustment technology and gloss adjustment. The gray scale adjustment technology uses two initial temperature of the hair color (capsule wall carbon particles (Tg), as well as the micro-capsules of different sizes to optimize the combination), get a good gray scale characteristics. laser pointer has to face some design problems.
Shade adjustment technology to change the high tones of carbon particles (Tg) the shade of the wall of capsule wall, and low tones of carbon particles (Tg) by mixing six kinds of hair color agent, to obtain from the continuity of the high-light to dark shades of light, one of the black agents to adjust photos of black degree, the same black and silver film. Gloss adjustment technology backing layer uV absorbent capsule internal scattering dull material to optimize the particle size and usage.
