Problems solved by technology

This ray may be blocked by limiting (vignetting) the insertion of the aperture or by an undersized lens that does not sit at the system aperture stop
However, in systems imaging more than one wavelength (where different wavelengths have different intensities), such vignetting may reduce too much light at low-intensity wavelengths, so that images for low-intensity wavelengths may not be discernible

example 1

[0079] image 3 A widefield imaging system 2000 is shown, according to one embodiment. The wide-field imaging system 2000 includes a common objective lens 2010 , a beam splitter 2020 , a first channel 2100 , a second channel 2200 and a third channel 2300 . The provisions of Table I can be used with this example.

[0080] Light from the object enters the common objective lens 2010, shown here as a triplet lens. A beam splitter 2020 (eg, a dichroic element) splits the light into two wavelength bands. In this particular example, beam splitter 2020 reflects a first wavelength range to first channel 2100 and transmits a second wavelength range to the second and third channels. In this particular embodiment, the first wavelength range is more intense than the second wavelength range.

[0081] The first channel 2100 may include a mirror 2110 for redirecting light towards a lens 2120 , a spatial stop 2130 and a detector 2190 .

[0082] The second and third channels 2200, 2300 are c...

[0090] Image 6 A widefield imaging system 3000 is shown, according to one embodiment. The wide-field imaging system 3000 includes a common objective lens 3010 , a beam splitter 3020 , a first channel 3100 and a second channel 3200 . The provisions of Table I can be used with this example. The first channel includes mirror 3130 , optical element 3120 , first aperture stop 3110 , and sensor 3190 . The second channel includes reject filter 3030 , mirror 3230 , optical element 3220 , second aperture stop 3210 , and sensor 3290 .

[0091] When an object imaged by imaging system 3000 has been illuminated with laser light, the backscattered light will form a random interference pattern, ie a speckle pattern. This speckle pattern changes when there is motion in the object. Here, the first wavelength range may include visible light and the second wavelength range may include laser light. Here, the beam splitter 3020 splits the light from the common objective lens 3010 into the vi...

[0093] Figure 7 A widefield imaging system 4000 is shown, according to one embodiment. The wide-field imaging system 4000 includes a common objective lens 4010, beam splitters 4020, 4025, 4030, 4040, 4050, a first channel 4100, a second channel 4200, a third channel 4300, a fourth channel 4400, a fifth channel 4500 and a fourth channel 4500. Six-channel 4600. The provisions of Table II can be used with this example.

[0094] Table II:

[0095]

[0096] The imaging system 4000 can image fluorescence, laser speckle, laser reflection and white light. The first beam splitter 4020 may transmit high flux light and reflect low flux light.

[0097] This high-flux light is incident on a second beam splitter 4025, which may or may not include a dichroic element, which reflects the visible wavelengths to a beam comprising lens 4110, aperture stop 4120, and sensor. 4190 in the first channel 4100. The second beam splitter 4025 transmits the laser reflection and laser speckle ligh...

Abstract

An optical system for use with a multi-channel wide-field imaging system, the optical system comprising: an objective lens; a dichroic element for splitting light into a first wavelength range and a second wavelength range, the dichroic element being divided into positioned to receive nearly parallel chief rays from the objective lens; a first channel lens system for receiving light of a first wavelength range from the dichroic element; and a second channel lens system for receiving light of a second wavelength range from the dichroic element Two-channel lens system.

Description

technical field [0001] The present disclosure relates generally to the field of optical systems, and in particular to optical systems for use in imaging systems having multiple image sensors, wherein the detected image signal amplitude in certain wavelength ranges is greater than in other wavelength ranges The weaker ones are orders of magnitude weaker. Background technique [0002] In imaging systems such as cameras, light emissions are captured from an object scene and the captured light is used to construct a spatial and chromatic representation of the object scene at the image plane. Images can be recorded by detectors or photosensitive media. Such imaging systems can be characterized by their operating volume and their performance within the operating volume. [0003] The operating space of an imaging system may include, for example, angular field of view, working distance, and spectral bandwidth. Imaging system performance may include, for example, spatial resolutio...
