Definitions
- a light beam is focused on the retina to produce a burn or coagulation spot.
- the light beam is emitted from conventional lasers by conventional laser operating procedures. These procedures typically employ, e.g..a single Argon blue-green or green laser, or a Krypton red laser.
- Argon blue-green laser is commercially available as a CavitronTMModel 3000 Argon Photocoagulation Laser.
- Fig. 1 is only an example, and other arrangements are also possible, in accordance with the procedure and/or treatment desired.
- most of the optical elements shown in the setup including the diffraction grating, are transmissive elements.
- reflective elements are more appropriate for the optical operation, such as when the main operating wavelength is in the far infra-red or ultraviolet spectral domains.
- the diffraction grating can also be materialized as a reflection grating.
- an N number of different holograms can be recorded on the same emulsion, each one having a different output direction ( ⁇ , ⁇ ) n , n-X, N, where ⁇ is the off-axis angle in a plane normal to the plane of the page.
- An important parameter here is the number of channels that this multiple hologram can handle simultaneously. This number is actually the number of different holograms which can be multiplexed together on the same substrate without reaching the refraction-index saturation of the recording material. Namely, the total sum of the desired refractive-index modulation for all the multiplexed channels must be less then the allowed maximum index modulation max of the recording material. It has been shown before that for recording materials such as dichromated gelatin or photopolymer, when the relation:
- z(x,y) is the depth of the relief; ⁇ is the wavelength of the laser, and vis the refractive index of the grating.
- Fig. 8 shows a diffraction grating arrangement 46, for use as the diffraction unit 38 of the system 2. modified slightly so that the operating beam and the auxiliary beam do not reach the diffraction unit 38 on a coincident travel path, but rather, travel to the diffraction unit 38 along parallel paths. Accordingly, the main laser 10 and auxiliary laser 16 are positioned so as to produce beams 6. 18 that travel in substantially parallel or parallel paths.
- the two beams 6, 18 are not combined together, but they are arranged as two co-linear plane waves.
- the gratings 98, 100 diffract each beam into its respective wave and into the identical diffraction pattern. Therefore, the two beams 6, 18 are focused by the focusing lens 102 onto the same points in the image plane (IP).
- FIG. 9 A modification of the system 2. illustrated in Fig. 1 is shown in Fig. 9.
- the modification consists of eliminating the second light source unit 14 and instead, utilizing the main channel laser unit 10 to also provide an aiming beam for the main operating beam 6.
- This is achieved by the intensity-reducing device 62 as governed by the controller 104, capable of substantially reducing the radiation passing therethrough, to obtain a laser beam of reduced intensity.
- This reduced intensity beam is then used to accurately aim the main operating beam 6 on the target plane.
- the system 2. when used to perform diabetic retinopathy is such that the surgeon can place multiple bu s with one shot of the operating laser beam. This results in fewer overall shots, as more bums are placed by the system of the present invention.
- the system of the present invention can also be used for photodisruption treatments.
- very short pulses of focused laser energy are emitted from the system 2, to cause optical breakdown and create cavitation through the expansion of a plasma bubble.
- the system of the present invention can also be used for oculoplastic and other cosmetic dermatological surgeries, when the main laser 24 is IR, CO 2 , ErNAG, or Alexendrite.
- the system is also useful in trabecular meshwork and photodynamic/photochemical therapy, using the same principle of multiple beams.
- other procedures where the system is useful include removals of hair, lesions, tattoos, and wrinkles; skin rejuvenation; collagen shrinkage; acne and traumatic scar treatment; xanthelasma; cellulite reduction, and the like.
- the system can also be used for hair transplants, as the diffraction grating allows for an array of holes to be drilled simultaneously into the patient's scalp. This results in the shortening of the procedure when compared to conventional methods.
