PRIORITY REFERENCE TO PRIOR APPLICATIONS [0001] This application is a continuation of and incorporates by reference U.S. patent application Ser. No. 10/682,655 filed Oct. 8, 2003, which claims benefit of and incorporates by reference U.S. patent application Ser. No. 60/423,345, entitled "System and Method for Pattern Delivery of Radiation and Glucose Detection," filed on Nov. 1, 2002, by inventor Brian Yen. TECHNICAL FIELD [0002] This invention relates generally to radiation delivery and characteristic analysis, and more particularly, but not exclusively, provides a system and method for characteristic analysis using pattern delivery of radiation to a biological object. BACKGROUND [0003] Diabetes is a disease of the pancreas in which the pancreas produces little or no insulin or when the body does not respond properly to insulin ("insulin resistance"). There is no cure for diabetes and diabetics must generally manage the disease on a daily basis. One aspect of management includes injecting insulin, such as Lantus, multiple times a day or dispensing it continuously via a pump. Improper administration of insulin can lead to severe side effects including hyperglycemia in which blood glucose levels are too high, which can lead to damage to nerves, blood vessels, and other body organs. Improper administration can also lead to hypoglycemia, in which blood glucose levels are too low, which can lead to passing out and even coma in worst case scenarios. Accordingly, as the amount of insulin dispensed needs to be varied based on blood glucose levels, diabetics must frequently monitor their blood glucose levels. [0004] Conventionally, home glucose monitoring is performed using a glucose blood meter, which yields results within a few minutes. In order to determine a blood glucose level, a person must first prick his or her finger with a small needle to collect a small amount of blood; the blood must then be placed on a test strip and inserted into the glucose test meter, which analyzes the blood for a blood glucose level. A diabetic can then adjust the amount of insulin to be dispensed accordingly. [0005] A disadvantage of the conventional method of glucose monitoring is that it requires the drawing of blood, which can be painful and inconvenient. Accordingly, as glucose monitoring is extremely important for diabetics because of the risk of side effects, a new glucose monitoring system and method is needed that is non-invasive and pain free. SUMMARY [0006] Embodiments of the invention provide a system and method for non-invasive monitoring of blood glucose levels. Embodiments of the invention can also be used for the analysis of other properties of biological and/or non-biological objects. Further, embodiments of the invention can be used for pattern delivery of radiation, for example, in cosmetic surgery such as tattoo removal or varicose vein removal. [0007] In one embodiment of the invention, a method comprises: detecting a pattern on the biological object; emitting radiation onto the detected pattern; collecting at least a portion of radiation that is reflected by the pattern on the object; and analyzing the collected radiation to determine a characteristic of the biological object. [0008] An apparatus to carry out the method comprises an imaging detector, a mirror, a radiation emitter, a radiation detection assembly, and electronics. The imaging detector is positioned to receive a first type of reflected radiation from the biological object. The mirror is adjustable to reflect radiation onto a pattern on the object. The radiation emitter is capable of emitting radiation of a second type and positioned to emit the second type of radiation onto the mirror. The radiation detection assembly is positioned to receive reflected radiation of the second type from the biological object. The electronics, which is coupled to the imaging detector, radiation emitter, mirror and radiation detection assembly, is capable of identifying a pattern on the object using reflected radiation data from the imaging detector; adjusting the mirror to reflect the second type of radiation onto the identified pattern; and analyzing a characteristic of the object using reflected radiation data from the radiation detection assembly. [0009] Accordingly, the apparatus and method provide a high signal to noise ratio without the need for high energy levels by using directed radiation, thereby avoiding interference problems. BRIEF DESCRIPTION OF THE DRAWINGS [0010] Non-limiting and non-exhaustive embodiments of the present invention are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified. [0011] FIG. 1 is a depiction of an eye; [0012] FIG. 2 is a diagram illustrating a device capable of pattern detection and pattern delivery of radiation; [0013] FIG. 3 is a block diagram of the device of FIG. 2; [0014] FIG. 4 illustrates a block diagram of the controlling electronics of the device of FIG. 2; [0015] FIG. 5 is a block diagram illustrating the persistent memory of the device of FIG. 2; and [0016] FIG. 6 is a flowchart illustrating a method of pattern delivery of radiation and analysis based on reflected radiation. DETAILED DESCRIPTION [0017] The following description is provided to enable any person having ordinary skill in the art to make and use the invention, and is provided in the context of a particular application and its requirements. Various modifications to the embodiments will be readily apparent to those of ordinary skill in the art, and the principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles, features and teachings disclosed herein. [0018] FIG. 1 is a depiction of an eye 100. The eye 100 is approximately 2.5 cm wide by 2.5 cm deep, with a height of 2.3 cm. The outer layer 120 of the eye is called the sclera and the approximately 1/6 of the sclera that is clear and exposed is referred to as the cornea. Extraocular muscles are coupled to the sclera and move the eye 100. The colored region 110 is the pupil of the eye 100 and is located in a second layer (i.e., choroid) of the eye 100 beneath the sclera 120. The choroid and the sclera 120 include a plurality of blood vessels, such as blood vessel 130, that supply blood to different regions of the eye. Generally, the blood vessels in the sclera 120 are the blood vessels in the body that are the most directly exposed to radiation. Accordingly, non-invasive analyte detection via spectrum analysis of blood is most easily and accurately performed using the blood vessels of the eyes. The blood vessels in the sclera 120 generally follow a non-linear path within the sclera and have varying thicknesses.
